Performance in Any 

Application 

Gate Valves 

Globe Valves 

In any fluid handling system, valves are the controlling element: starting or stopping flow, regulating or throttling flow, 

preventing backflow, or relieving and regulating pressure. 

Since Stockham valves are used in a variety of applications, the following descriptions may provide a basic guideline in 

the selection of steel valves. 

Gate valves serve as efficient stop valves with flow in either direction. They are commonly used where a minimum pressure 

drop is important. Throttling is not recommended because partially open gate valves exhibit flow characteristics not 

conducive to accurate and consistent flow control. Also, the valves may be damaged by the high velocity across the seats. 

They function best fully open or fully closed. 

Globe valves are ideal for throttling service. Their flow characteristics permit accurate and repeatable flow control. However, 

caution must be exercised to avoid throttling close to the seat or when pressure drop exceeds 20% of the valve’s upstream 

pressure. This creates excessive noise, vibration, and possible damage to valves and piping. When these conditions are 

anticipated, consult Stockham sales personnel for recommendations. 

Swing Check Valves 

Swing Check valves prevent reversal of flow through pipe lines. Most Stockham swing check valves can be installed in 

horizontal or vertical, upward flow, piping. They offer low resistance to flow and are particularly suited to low velocity 

service. 

How to Specify and Order the Correct Valves 

Size 

Nominal size of the pipeline into which the valve will be placed must be determined. 

Comprehensive data on flow characteristic and pipe properties are contained in the 

Engineering Data Catalog. 

Valve Material 

The following facts should be considered in determining the correct valve body, 

trim, and packing material. 

• The media to be controlled. 

• The temperature of the media. 

• The possible extraordinary stresses affecting the valve. 

• Safety standards and/or piping codes. 

Type of Valve 

A few minutes spent in reading some simple valve facts on pages 3 and 4 will 

prove helpful. 

Pressure/Temperature Rating 

Please pay careful attention that the PRESSURE/TEMPERATURE RATINGS are in 

keeping with the requirements of the application. 

Valve End Connections 

Considerations as to pipeline integrity, future maintenance, corrosion factors, field 

assembly, weight and safety should be given in determining the method of connecting 

the valve in the pipeline. 

CAUTION: When servicing, disassembling, or disposing of valves containing asbestos gaskets or packing, avoid breathing dust or fibers from these parts. Disposal of 

asbestos and asbestos related products should comply with local, state and federal laws and regulations. 

NOTE: In keeping with our policy of continuous product improvement, we reserve the right to institute changes in design, material, dimensions, 

and specifications without notice and without incurring any obligation to make such changes and modifications on the product previously 

or subsequently sold.

Installation, Marking, and 

Identification 

When purchasing valves, reference should also be made to MSS SP-92, “Valve User Guide.” Inquires relating specifically to 

Stockham products may be referred to our factory or customer service department. 

Marking and identification of Stockham steel valves conforms to ASME 16.34 Standard Marking System for Valves, Fittings, Flanges, and Unions (MSS 

SP-25) as well as the appropriate BS valve standard. 

It is important to properly identify valves in service to allow for the ordering of replacement parts or address questions or concerns relating to our 

products. Body markings and information shown on the identification plate helps to properly identify valves, allowing timely and accurate responses to 

such inquiries. 

Integrally cast body marking data includes the following information and helps to provide traceability: 

• Stockham name 

• Pressure class 

• Valve size 

• “Steel” symbol for the grade of material (i.e. WCB for carbon steel) 

• Heat number casted on body and bonnet 

The body markings are supplemented by an identification plate which, depending on valve type and size, is mounted in the most practicable position. Tag 

location for gate and globe valves is typically on the valve yoke. Check valve tags are typically mounted on the rim cap. 

Identification plates bear the following information: 

• Catalog number 

• Valve size 

• Body material 

• Disc material 

• Stem material 

• Seat and trim material 

• Pressure and temperature rating

Typical Bolted Bonnet Gate Valve Features 

Stockham gate valves offer the ultimate in dependable service for steam, air, gas, oil, oil vapor, and high pressure installations. 

All have straight-through ports to assure minimum turbulence, erosion, and resistance to flow. The valves are available in a 

wide variety of trims. 

1. Body: Body is cast to provide liberal strength to meet operating 

conditions and to permit unobstructed flow. Turbulence, erosion, and 

pressure drop are minimized. 

Cast steel gate valves are available in flanged ends designed to conform 

to ASME B16.5 standards. 

2. Integral Yoke and Bonnet: Some designs incorporate a two- 

piece bonnet and yoke. All bonnet assemblies are cast and 

finished to the same exacting tolerances as the bodies for 

accurate alignment of stems and ease of sealing. Bonnet 

joint varies from flat face gasket-joint to ring-type bonnet 

joint, depending on class. 

3. Seat Rings: Seat rings are seal welded to eliminate leak 

path behind rings and for long, trouble-free service. The 

surfaces are precision ground to fit accurately to the disc. 

4. Wedge: The one-piece flexible wedge provides accurate 

alignment of mating seating surfaces so the valve can 

absorb piping stress without leakage. Also, it avoids any 

tendency to stick in the seated position. 

5. Stem: The T-head disc stem connection prevents lateral 

strain on the stem for smooth, easy operation. Accurately 

cut threads engage the yoke sleeve for positive control of 

disc position. 

6. Yoke Sleeve 

7. Handwheel Nut 

8. Yoke Sleeve Retaining Nut 

9. Packing: Packing contains corrosion inhibitor to avoid 

stem pitting. Stuffing box is deep, assuring long packing life 

10. Gland: Gland is two-piece ball-type which exerts even 

pressure on the packing without binding the stem. 

11. Gland Flange 

12. Gland Eye Bolts: Eyebolts swing aside for ease in repacking 

the stuffing box.

Typical Globe Valve Features 

Stockham globe valves are highly efficient for services requiring frequent operation and throttling when pressure drop across the valve is 

about 20% of inlet pressure. Closer throttling, creating higher pressure drops, may cause cavitation or excessive velocities which could 

cause high noise levels, vibration, and possible damage to the valve or adjacent piping. Globe valves can be equipped with optional operators 

and are available with a variety of trims to match service requirements.

Typical Swing Check Valve Features 

Swing check valves are used to prevent reversal of flow in horizontal or vertical pipelines. In vertical lines, or for any angle 

from horizontal, they can be used for upward flow only. 

Check valves are automatically actuated. They are opened and sustained in the open position by the force of velocity pressure, 

and they are closed by the force of gravity. Seating load and resultant tightness is dependent upon back pressure. 

The disc and associated moving parts may be in a constant state of movement if the velocity pressure is not sufficient to 

hold the valve in a wide open and stable position. Premature wear and noisy operation or vibration of the moving parts can 

be avoided by selecting the size of check valve on the basis of flow conditions. The minimum velocity to hold a swing check 

valve in the wide open and stable position is expressed in the formula: 

The value for ν is equal to flow in feet per second and ν is the specific volume of fluid in cubic feet per pound. Sizing swing 

check valves on this basis may often result in the use of valves that are smaller than the pipe in which they are used, 

necessitating the use of reducers for installation. The pressure drop will be no greater than that of the larger valve that is 

only partially open, and the valve life will be greatly extended. An added bonus is the lower cost of the smaller valve. 

There is no tendency for the seating surfaces of swing check valves to gall or score because the disc meets the flat seat 

squarely without rubbing contact upon closing. 

Stockham cast steel swing check valves can be furnished with outside lever and adjustable weight if desired. With the lever 

and weight mounted so that the weight assists the disc in closing, the valve closes more rapidly when flow stops, thus 

minimizing reversal of flow and resultant surge and shock. With the lever and weight mounted to balance the weight of the 

disc, the valve becomes more sensitive to low inlet velocities. 

1. Body: Strong construction assures maximum 

safety over the recommended pressure and temperature 

range. Available in Flanged End body 

configuration. 

2. Cap: Cap permits access to hinge and disc 

without removing valve from line. 

3. Disc: Disc is designed to close on its own 

weight to stop backflow from gaining sufficient 

velocity to create damaging shock.
