Permutit® Multiport Valve 

The Permutit® Multiport Valve performs the function of five 

individual valves. Already proven in thousands of applications, the 

Permutit® Multiport Valve has been utilized on all types of filters, 

softeners and demineralizers within the industrial and municipal 

water treatment sectors. 

In addition to not requiring an air supply, many plant personnel 

prefer the Multiport Valve due to its long-term reliability, simplicity 

of operation and ease of maintenance. The Multiport is available 

for completely automatic operation requiring only electric power 

for operation or it can be ordered for manual operation. 

Features 

Only one valve needs to be maintained, while it replaces 

five valves 

Valve remains in position during an electrical outage and can 

be operated manually until the outage is over 

Instrument air is not required 

Streamlined waterways lower pressure loss 

Spare parts kits are available to upgrade from manual to 

automatic operation 

Multiport Valve Applications 

The Permutit® Multiport Valve can be applied in several ways: 

For systems with existing multi-ported valves from other 

manufacturers, the Permutit® Multiport Valve can be utilized to 

replace worn or obsolete models or models that are no longer 

available. We will work closely with your plant personnel and 

supply all the documentation and customer support you may 

require for a smooth transition. 

For installations with existing Permutit® Multiport Valves, our 

factory-reconditioning program can return your valves to optimum 

performance. Our personnel will completely disassemble your 

valves, submit a detailed list of recommendations and repair, 

repaint and return your valves to your plant for re-installation or to 

be put into your inventory as a spare. With reconditioned valves, 

we offer a one-year warranty. 

For systems with individual valves, one Multiport Valve can be 

utilized to replace up to five individual valves. Our customer 

support team can assist you in determining the optimum operating 

scheme for your operation and assist your personnel for a smooth 

changeover. 

For plants with new or increased water treatment needs, we can 

supply an entire water treatment system equipped with Multiport 

Valves.

Safety, Maintenance and Lubrication 

When working near or performing maintenance on any rotating 

equipment, extreme care should be taken to ensure maintenance 

personnel are adequately trained and protected with the 

appropriate safety equipment, such as safety glasses with rigid side 

shields or a face shield. Maintenance personnel should avoid 

wearing loose or dangling clothing, necklaces, rings, earrings or 

other items that could become entangled in the machinery. 

Slide Lubrication 

Multiport Valves must be lubricated on a regular basis with the 

silicone lubricant that is item 67 on the Parts List to ensure 

optimum, long-term performance. This is the only lubricant 

approved for use with the Multiport Valve. 

For normal operating conditions, the lubricant must be applied on 

a weekly basis at a minimum. For high temperature operating 

conditions, short service runs with frequent regenerations or other 

adverse conditions, the valve should be lubricated more 

frequently. To ensure the lubrication process is completed as based 

upon the operating conditions, a record should be maintained 

indicating when each valve is lubricated. Failure to apply the 

lubricant as required will result in excessive wear to the internal 

sliding parts and valve leakage. A hand operated, manual valve 

that no longer turns easily and an automatic valve that chatters are 

both indications the valve is long overdue for lubrication and 

excessive wear may have already occurred. 

For automatic valves, the power supply to the control box must 

first be disconnected before the lubrication process is begun. The 

following steps apply to both automatic and manual valves: 

1. Close the inlet and outlet isolation valves. 

2. Open a manual vent or sample valve to relieve the pressure on 

the valve. 

3. With the valve in the SERVICE position, use a grease gun to 

inject a small quantity of lubricant through each of the fittings 

located at the rear of the valve. The number of fittings 

will depend upon the size of the valve. 

4. Using the hand crank, rotate the valve to the WASH position 

and lubricate again, so the internal tubes direct the lubricant 

between the sliding surface of the rotating slide and the 

stationary port plate. 

5. Turn the valve several complete rotations to ensure distribution 

of the lubricant. 

6. Return the valve to the SERVICE position. 

7. For automatic valves, reconnect the power. 

8. Open the inlet and outlet isolation valves. 

Gear Case Lubrication 

On a monthly basis, the oil in the valve gear case should be 

checked to ensure it is at a level that will result in splash lubrication 

of gearing. The oil

Multiport Valve Operation 

Service 

During Service, raw water enters the valve and flows 

downward from the top of the vessel to the bottom. 

The treated water is collected and directed through 

the Multiport Valve to service. 

Backwash 

During the Backwash cycle, raw water enters the 

Multiport Valve and flows upward from the bottom to 

the top of the vessel. The water then returns to the 

valve and flows out to the drain. 

Regeneration 

During the Regeneration cycle, raw water enters the 

valve and draws in the regenerating solution using an 

external ejector (optional). The regenerant solution 

flows downward through the bed to the bottom of 

the vessel, returns to the valve and then flows out to 

the drain. 

Rinsing 

During the Rinse cycle, raw water enters the valve 

and flows downward from the top to the bottom of 

the vessel where the water is directed through the 

valve to the drain.

Notes: 

1.) Top and bottom flanges omitted for lined 

valves. 

2.) Lined valves do not have gauge or 

pilot connection. 

3.) All flanges are flat faced.

should be changed every six months using SAE 80W90 gear oil. 

Care should be taken so dirt or water does not enter the gear 

case, as this will contaminate the oil. Do not overfill as this will 

result in oil leakage. 

Replacement of Slide and Port Plate 

Note: The parenthetical numbers are the item numbers as 

shown in the exploded parts drawing. 

7. To replace the port plate gasket (3) in an unlined valve 

when the old port plate is in serviceable condition, 

completely clean the gasket side of the port plate using a 

flat tool. Apply fresh gasket cement (3M Scotch Grip 

2141or equivalent) to the gasket side of the port plate and 

to the port plate side of the port plate gasket and cement 

the surfaces together. Then install the port plate with the 

cemented gasket as outlined in Step 6. 

After extended operation, increased leakage may occur. This 

may manifest itself as flow out of the backwash and/or rinse 

ports or internal bypassing of hard water to service. It usually 

results from excessive wear to the sliding parts, damage to the 

port plate gasket (3) or scoring due to foreign matter being 

wedged between the slide surface (6) and the port plate (4). 

To replace these parts: 

1. Remove the packing nuts (46) and grease (46) fittings. 

2. Remove the cap screws (15). 

8. To replace the port plate (4) in a lined valve, the old sealant 

between the port plate and the body will need to be 

completely removed. Be extremely careful when cleaning 

the surfaces of the lined body, so the lining is not damaged. 

Apply new sealant (68) to the cleaned surfaces of the body 

that come in contact with the port plate. The sealant will 

serve as filler for any minor irregularities on the seating 

surfaces and make the port plate gasket unnecessary. 

Install the port plate, replace the fillister head screws (5) 

and remove any extraneous sealant. Then check and adjust 

for flatness using the techniques in Step 6. 

3. Using appropriate lifting equipment to support the weight 

of these parts, lift off the bonnet (8) from the body 

assembly. The slide assembly (6) will be removed with 

the bonnet. 

4. Examine the condition of the slide and port plate. If the 

slide assembly is worn, slip it off the slide shaft (11) and 

replace it with a new part. Note: The slide casting and 

facing are integral parts and must be replaced as an 

assembly. Before replacing the slide, lubricate the slide 

shaft with silicone lubricant (67). Be sure the slide shaft 

keys (83 and 84) are in place. For lined valves, ensure the 

valve packing rings (64) and retainers (63) are installed 

before the slide assembly (6) is placed on the slide shaft 

(11). One ring and one retainer should be placed on each 

side of the slide spring (7). 

9. Insert new bonnet gasket (2). 

10. Reassemble the remaining parts of the valve in reverse 

order from the disassembly procedure. Do not use the valve 

for at least one hour before admitting water to ensure 

the sealant cures properly. 

Multiport Valve Motor Couplings Note 

To ensure the motor couplings are ordered 

correctly, the bore and length should be 

measured. After the measurements have been 

verified, select the part number(s) from the

5. If the port plate (4) and/or the port plate gasket (3) are 

worn, remove the fillister head screws (5) and lift the port 

plate off the body (1). 

6. To replace the port plate (4) in an unlined valve, the old 

port plate gasket (3) will need to be completely removed. 

Using a flat tool, clean off the gasket seating surfaces of the 

body (1). When replacing the port plate and gasket with 

new parts, the port plate gasket will be shipped cemented 

in place to the port plate. Install the new gasket and port 

plate, replace and tighten securely the fillister head screws 

(5) and then back off the screws by ¼ turn. It is extremely 

important that the port plate, as installed, is flat at all 

locations to within 0.002”. To check this, use a machinist’s 

straight edge and a 0.002” feeler gauge to verify the 

flatness over the entire surface. If it is not flat, adjust the 

tightening of the fillister head screws (5) and recheck to 

achieve the specified flatness.
