Double Check Valve 


DC-4A Series 

TOP ENTRY DOUBLE CHECK VALVE ASSEMBLY 

The Apollo MODEL DC4A Double Check Valves are designed to prevent contamination of the 

potable water supply due to back-siphonage or backpressure from substances that are 

objectionable, but non-health hazards. The modular check valve cartridges have replaceable 

seats and reversible silicone seat discs. Apollo ball valve shut-offs with stainless steel handles 

and nuts are 

standard. 

Sizes 1/2", 3/4”, 1", 1-1/4", 1-1/2", 2" 

OPERATION 

During normal flow conditions, the two check valves are held off their seats, supplying water 

downstream. Each check valve is designed to maintain a minimum of 1 psi across the valve 

during normal operation. Should the downstream pressure increase to within 1 psi of supply 

pressure, both check valves will close to prevent a backflow condition.

DC-40 Series 


The Apollo DC-40 Series Top Entry Double Check Valve Assembly is designed to 

protect against backflow from a cross-connection of non-health hazard pollutant. Within the 

assembly are two mechanically independent, spring-loaded poppet type check valves set in 

an integral cast bronze body. Both check valves are designed at an inclined angle upward from 

horizontal centerline of the assembly, and all test cocks are mounted at the top to assure easy 

access during repair and maintenance when unit is installed in a pit or tight places. 

Sizes 3/4", 1", 1-1/4", 1-1/2", 2" 

OPERATION 

During normal flow conditions, the two poppet check valves are held off their seats, supplying 

water downstream. Each check valve is designed to maintain a minimum of 1 psi across the 

valve during normal operation. Should the downstream pressure increase to within 1 psi of 

supply pressure, both check valves will close to prevent a backflow condition.

Double Check Detector 


DCDA-4S SERIES (Previously Model DCDA) 

DOUBLE CHECK DETECTOR ASSEMBLY 

The Apollo Model DCDA-4S Double Check Detector Assembly is designed to provide double check 

protection against cross-connection of non-potable (non-hazardous) water into the safe drinking 

water system; and at the same time offers precise monitoring capability to detect leakage or unauthorized 

use of water from fire or automatic sprinkler systems. The unit consists of two independently 

acting, spring loaded check valves with inlet and outlet resilient wedge gate valves and a by-pass 

assembly consisting of a water meter, double check valve assembly with shut-off valves and test 

cocks. 

Size 10" 

OPERATION 

During normal conditions, if the downstream pressure of the assembly increases above the supply 

pressure or there is a reverse direction of flow; the line and by-pass double check valves will close 

to prevent backflow. If the second check valve of either the line or by-pass is prevented from 

closing tightly, the first check valves will still provide protection from a backflow condition. The line 

and by-pass double check valves will remain closed during the no flow condition. If there is a low 

flow demand (up to a minimum of 3 gpm) of water downstream, which may be caused by a system 

leak or unauthorized use, the flow is routed through the water meter to monitor such consumption. 

Higher flow will cause the main line double check valve to open while water continues to 

flow at the by-pass at a rate below capacity.

N AND Z FLOW REDUCED PRESSURE PRINCIPLE 

The Apollo Series RP-40 Reduced Pressure Principle Backflow Preventer is designed to give 

maximum protection against backflow caused by either back-pressure or back-siphonage. The 

durable, but economical, device is easily maintained in the line without any special tools. It 

consists of two independently acting spring-loaded poppet check valves with an automatic 

differential relief valve located between the check valves. The diaphragm and the sensing 

passage are built into the all bronze body to eliminate possible damage. The assembly offers 

installation flexibility by providing inlet and outlet bronze elbows to meet space requirements, 

adaptability and lower installation cost. The No. 3 and No. 4 test cocks are mounted at the top to 

assure easy access during repair and maintenance when unit is installed in tight places. 

OPERATION 

During normal flow conditions, the two check valves are held off their seats, supplying water downstream. 

The relief valve is held shut by supply pressure acting through the internal sensing passage, 

on the relief valve diaphragm. In the area between the check valves, called the zone, the pressure is 

maintained at approximately 7 psi lower than supply pressure. Should a back-pressure or backsiphonage 

condition occur, the second check valve will seal, prohibiting the backflow of water. Should 

the second check valve become fouled, the pressure in the zone will increase causing the differential 

relief valve to open to atmosphere. This will maintain the pressure in the zone at least 2 psi lower 

than supply pressure.

RP-40 Series 


The Apollo Series 40-RP Reduced Pressure Backflow Preventer consists of two 

independently acting, spring-loaded center stem guided check valves with a differential 

pressure relief valve located between the check valves. The all bronze relief valve module is 

easily removed from the ductile iron check valve body. Pressure sensing passages are built 

into the bronze relief valve module to prevent possible damage from mishandling or 

vandalism. The unit is available with inlet and outlet shutoff valves. Four test cocks, three on 

the backflow preventer valve body and one on the inlet shutoff valve, complete the assembly. 

OPERATION 

During normal flow conditions, the two check valves are held off their seats, supplying 

water downstream. The relief valve is held shut by supply pressure acting through the 

internal sensing passage, on the relief valve diaphragm. In the area between the check 

valves, called the zone, the pressure is maintained at approximately 7 psi lower than 

supply pressure. Should a back-pressure or back-siphonage condition occur, the second 

check valve will seal, prohibiting the backflow of water. Should the second check valve 

become fouled, the pressure in the zone will increase causing the differential relief valve to 

open to atmosphere. This will maintain the pressure in the zone at least 2 psi lower than 

supply pressure.

RP-40 Series 




The Apollo Series RP-40 Reduced Pressure Backflow Preventer consists of two independently 

acting, spring-loaded center stem guided check valves with a differential pressure relief valve 

located between the check valves. The relief valve module is easily removed from the ductile 

iron check valve body. Pressure sensing passages are built into the relief valve module to 

prevent possible damage from mishandling or vandalism. The unit is available with inlet and 

outlet shutoff valves. Four test cocks, three on the backflow preventer valve body and one on 

the inlet shutoff valve, complete the assembly.

downstream. The relief valve is held shut by supply pressure acting through the internal sensing 

passage, on the relief valve diaphragm. In the area between the check valves, called the 

zone, the pressure is maintained at approximately 7 psi lower than supply pressure. Should a 

back-pressure or back-siphonage condition occur, the second check valve will seal, prohibiting 

the backflow of water. Should the second check valve become fouled, the pressure in the zone 

will increase causing the differential relief valve to open to atmosphere. This will maintain the 

pressure in the zone at least 2 psi lower than supply pressure.

RP-4D Series DEFENDER ® 

RP-4D SERIES REDUCED PRESSURE PRINCIPLE ASSEMBLY 

The Apollo Valves RP-4D Reduced Pressure Backflow Preventer Defender provides maximum 

backflow protection in a lead free, short lay length, compact package. The assembly consists of 

two independently acting, spring loaded, poppet type check valves with a differential pressure relief 

valve located in the zone between the checks. The all stainless steel check valve modules are 

easily removed from the ductile iron body via a large access cover. The stainless steel relief valve 

module is also accessible and removable. The Defender is available with monitored butterfly 

valves. Ninety-degree elbows are also available within the shut-off valve envelope for compact 

installations. 

OPERATION 

During normal flow conditions, the two poppet style check valves are held off their seats, supplying 

water downstream. The relief valve is held shut by supply pressure acting through the sensing 

tube. Should a back-pressure or back-siphonage condition occur, the second check will seal, 

prohibiting the backflow of water. Should the second check become fouled, the pressure in the 

zone will increase causing the differential relief valve to open to atmosphere, discharging the contents 

of the zone.

RPDA-40 Series 

40 - 7 0 X - X X 



REDUCED PRESSURE DETECTOR ASSEMBLY 

The Apollo Series RPDA-40 Reduced Pressure Detector Assembly is designed to provide 

reduced pressure principle protection against cross-connections that present a health hazard, 

and at the same time detect leakage or unauthorized use of water from fire or automatic sprinkler 

systems. The mainline unit consists of two independent spring-loaded, poppet type check valve 

assemblies with a diaphragm actuated and spring-loaded, relief valve assembly located between 

check valves. Two resilient wedge gate valves and four test cocks complete the mainline unit. The 

by-pass consists of an approved reduced pressure assembly, four test cocks, two shut-off valves 

and a water meter. 

OPERATION 

During no flow conditions, the mainline and by-pass check valves will remain closed. Also, both 

mainline and by-pass relief valves stay closed due to the pressure differential between supply and 

zone pressure. If there is a low flow demand (up to a minimum of 3 gpm) of water downstream, 

which may be caused by a system leak or unauthorized use, the flow is routed through the water 

meter to monitor such consumption. Higher flow will tend to open the mainline check valves at 

which point water continues to flow at the by-pass at a rate below capacity. In the event pressure 

increases downstream, tending to reverse direction of flow, both check valves in the mainline and 

by-pass are closed to prevent backflow. If the second check valve in either the mainline or by-pass 

is prevented from closing tightly, leakage into the reduced pressure zone increases pressure and 

will cause the relief valves to open. If the supply pressure drops to atmosphere or lower than the 

reduced pressure zone, the relief valves will open creating an internal air gap in both assemblies. 

Contact local water authorities for installation/service requirements.

4D SERIES REDUCED PRESSURE DETECTOR ASSEMBLY 

The Apollo model RPDA-4D Series is designed to provide reduced pressure principle protection 

against cross-connections that present a health hazard; and at the same time offers precise 

monitoring capability to detect leakage or unauthorized use of water from the fire or automatic 

sprinkler system. The RPDA-4D Series is available in sizes 2-1/2” - 10”. The unit consists of a 

mainline 4D Series Reduced Pressure Principle assembly with two independently acting poppet 

type check valves with a diaphragm actuated and spring loaded relief valve assembly located 

between the checks. A bronze by-pass line by-passes the 2nd check. The by-pass line consists of 

a meter, a single check, shut-off isolation valves, and test cocks. The relief valve on the mainline 

device maintains high hazard protection, as the by-pass is downstream of the reduced pressure 

zone. 

OPERATION 

During normal conditions, the mainline device provides normal reduced pressure backflow 

protection against back-siphonage or backpressure. If a backflow condition should occur the two 

mainline poppet style checks along with the by-pass single check will close tight. If there is a low 

flow demand (up to a minimum of 2 gpm) of water downstream, which may be caused by a system 

leak or unauthorized use, the flow is routed through the water meter to monitor such consumption. 

Higher flows will open the mainline checks as required. 

FEATURES

OPERATION 

During flow conditions, the flow of water lifts the float disc and seals the atmospheric vent at all rates 

of flow, preventing leakage. When a negative pressure is created at the supply line or when the water 

supply valve upstream of the device is closed, the float disc will fall, thus opening the atmospheric vent. 

This prevents back-siphonage and creation of vacuum at the discharge line.

Spill Resistant Vacuum Breaker 


SVB-4W Series 

SPILL RESISTANT VACUUM BREAKERS 

The Apollo Series SVB-4W Spill Resistant Vacuum Breaker is designed to prevent 

contamination of the potable water supply due to back-siphonage. The SVB is ideally suited for 

continuous pressure, indoor applications where water spillage is undesirable. The device has a 

straight through flow path for minimal head loss. All components are easily accessible for easy 

repair and maintenance. All components are made of corrosion resistant materials for years of 

reliable service. Should be installed 6” above all downstream piping. 

Sizes 1/4", 3/8", 1/2" 

OPERATION 

During normal flow conditions, the check valve remains open and the atmospheric vent seals in 

the bonnet assembly. As the line pressure falls to 1 psi, the spring loaded atmospheric vent 

opens and the check valve closes, breaking the vacuum and thereby preventing backsiphonage. 

Water is not allowed to spill at any time during operation.

Dual Check w/ Atmospheric Port 


DCAP Series 

DUAL CHECK WITH ATMOSPHERIC PORT BACKFLOW PREVENTER 

The Apollo DCAP Series Backflow Preventer is designed to protect residential and commercial water 

supply lines from back-siphonage or back-pressure of non-potable (non-hazardous) substances. It 

has an intermediate atmospheric vent to insure protection from backflow conditions. It consists of two 

independently acting and spring-loaded check valves in a corrosion resistant material. 

Sizes 1/2", 3/4" 

OPERATION 

During normal flow operation, the vent valve is closed, and the two check valves are open allowing 

flow of water through the unit. Each check valve is designed to hold at least 1 psi in the direction of 

flow. When a back-siphonage condition occurs, both check valves close and the atmospheric vent 

opens to permit air to enter the intermediate zone. In the event of back-pressure and if the second 

check valve is prevented from closing tightly, leakage will be vented to the atmosphere through the 

vent port.

OPERATION 

Each of the two spring-loaded check valves is designed to open at 1 psi differential in the 

direction of flow. The check valves will remain tightly closed until there is a demand for water 

downstream. If the downstream pressure of the device increases above the supply pressure or 

there is a reverse direction of flow, the check valves will close to prevent backflow. If the second 

check valve is prevented from closing tightly, the first check will close to provide protection 

from a backflow condition.

CARBONATED BEVERAGE BACKFLOW PREVENTER 

The Apollo CBBP Series Carbonated Beverage Backflow Preventer (CBBP) is designed to prevent 

the contamination of the potable water supply due to backflow when installed on water 

distribution lines serving beverage dispensing equipment. The device consists of two independently 

acting check valves biased to a normally closed position. A normally open atmospheric port 

is located between the check valves. During backflow conditions, the port vents gases and/or liquids. 

Additionally, the CBBP is equipped with a 100 mesh integral strainer screen at the inlet. All 

wetted areas of the device are non-toxic, corrosion resistant, and approved for use with potable 

water. The CBBP is suitable for supply pressures to 150 psig and water temperatures from 33˚ to 

130˚ F. 

OPERATION 

Under static (non-flowing) conditions, the check valves remain in the closed position. When a 

valve is opened downstream (i.e. a drink is delivered from the beverage dispensing unit), the 

check valves open and permit the flow of water. Under backflow conditions, the diaphragm seat 

on the first check lifts and permits flow through the atmospheric port located between the two 

check valves. The strainer insures debris does not enter the carbonator. 

FEATURES 

• Compact Design 

• Lowest head loss 

• Atmospheric vent provides indication 

of problems 

• Integral strainer for equipment protection 

• Available in SAE & NPT connections 

• Repairable check assemblies 

• Non-metallic body for corrosion resistance 

• CSA Certified to ANSI/NSF-61 

• ASSE1022

Hose Connection Dual Check 


HBV2 SERIES 

3/4" HOSE CONNECTION VACUUM BREAKERS 

Apollo’s HBV Hose Connection Vacuum Breakers are designed to prevent cross-connection caused by 

back-siphonage. They consist of a single check valve with atmospheric vacuum breaker vent. They feature 

a break-away set-screw for tamper-proof protection. They are not suitable 

for continuous pressure applications. 

OPERATION 

At no flow situations, the check disc seats against the diaphragm with the atmospheric vent open. This 

prevents back-siphonage or backflow of water. At flow conditions, the spring-loaded check disc opens, thus 

allowing flow of water through the device and at the same time the diaphragm seals the atmospheric vent.

HBDUC SERIES 

3/4" HOSE CONNECTION DUAL CHECK 

The Apollo Series HBDUC is designed to provide an in-line testable hose connection that will prevent 

backflow due to back-siphonage or low head back-pressure. Each device consists of two independent 

checks, forced loaded in the closed position with an atmospheric vent between the checks. The device is 

threaded for hose connection at both the inlet and outlet with a break-away set screw on the inlet for 

tamper proof installations. These devices are not suitable for continuous pressure applications. 

OPERATION 

During initial pressurization, the inlet check shuttles forward to close the atmospheric vent. As flow is 

established, both the inlet and outlet check open to allow flow through the device. If a backflow condition 

is present, then both checks will close and the atmospheric vent opens to introduce air and break the 

siphon.

LFDUC Series 

LABORATORY FAUCET DUAL CHECK BACKFLOW PREVENTER 

The Apollo Series LFDUC is designed to provide protection against back-siphonage wherever a hose is connected 

to a faucet. The device consists of two independently acting checks with an intermediate relief port or 

vent. It is suitable for supply pressure up to 150 psig and a temperature range of 33°F-180°F. Not suitable for 

constant pressure conditions. 

Sizes 1/4", 3/8" 

OPERATION 

During normal flow conditions, the two checks are held off their seats, supplying water downstream. The vent 

is held shut by supply pressure acting on the diaphragm. If the supply pressure should fall below atmospheric, 

the second check will close due to internal spring pressure and the vent will open to introduce air into the supply 

line and break the siphon. 

NOTE: This device should only be installed where spillage of water could not cause water damage.

EXV Series 

THERMAL EXPANSION RELIEF VALVES 

The Apollo EXV Thermal Expansion Relief Valves are designed primarily to relieve excessive water 

pressure build-up caused by thermal expansion. 

In a closed hot water piping system, as water is heated, thermal expansion occurs. The increase of 

pressure will exert unwarranted stress on the system components, which may reach harmful levels 

well before the emergency setting of the main relief valve is reached. By installing the Series 

EXV, it will control any amount of expanded water without causing pressure increase to exceed 

maximum setting. 

FEATURES 

• Prevents excessive pressure build-up 

• Protects plumbing fixtures 

• Extends water heater life 

• Compact and lightweight design 


• Easy to install and requires no special tool

in place of any IBBM gate valve or plug valve. 

With their full port design, these valves assure an unobstructed, turbulence-free flow that gate and 

butterfly valves can’t match. Low profile handle for easy installation in tight places. Sizes from 21/2" 

to 8". Rated 125 WSP, 200 WOG, with maximum operating temperature of 140°F.
