Iron Valves
Stockham iron body valves are proven performers in mechanical systems of commercial buildings throughout
America. Chemical plants, steel mills, shipyards, refineries, pulp and paper mills, and utilities have also found that
Stockham iron body valves do the job better and longer for their many general services.
QUALITY MANAGEMENT
Stockham is committed to a philosophy of total quality management.
It begins with design, to comply with pertinent MSS and ASME
Standards. Continuous improvement are applied in a process to
improve materials and services to meet or exceed customer needs.
DESIGN:
GATE VALVES-CLASSES 125 and 250

The iron used as the basic valve material conforms to the chemical
and physical requirements of the American Society of Testing and
Materials A-126 Class B for Cast Iron Valves.
Packing Gland Assembly—Glands and gland flanges have a
ball and socket joint which assures alignment. It provides for proper
packing compression without binding against the stem.

The temperature shown for a corresponding pressure rating is the temperature of
the pressure containing shell of the component. In general, this temperature is the
same as that of the contained fluid. Composition disc valves are excluded from these
ratings.

Stuffing Box—NRS valves have stuffing boxes assembled to
bonnets to accommodate the packing gland assembly.
Seat Ring—Buttress-type seat rings are bottom-seated with
accurately machined faces to match disc faces.
Handwheel or Operating Nut—Handwheels have large diameters
for good leverage. Operating nuts, 2" square may be furnished on
any NRS valve if specified.
Iron Valves
Yoke Bushing—Yoke bushings on OS&Y valves have Acme threads
for stem engagement, and handwheels fit snugly over bushings.
Handwheels are securely locked to yoke bushings with locknuts.
Bolted yoke cap secures the yoke bushing to yoke.
Body—Body sections are evenly distributed for maximum strength.
Dimensions and drilling of end flanges of cast iron valves conform to
the ASME Standard B16.1 for Classes 125 and 250 Cast Iron Flanges.
Face-to-face dimensions comply with ASME Standard B16.10.
DESIGN:
GLOBE AND ANGLE VALVES-OUTSIDE SCREW AND
YOKE-CLASSES 125 and 250
Stem—Stems are machined with Acme threads which fully engage
the yoke bushing threads at all times.
Handwheel—Handwheels have large diameters for ample
leverage.
Yoke Bushing—Accurate Acme threads engage stem threads. Set
screws fasten yoke bushings to yoke.
Body—Bodies are designed with uniform sections evenly distributed
for maximum strength. Dimensions and drilling of end flanges on
flanged valves conform to the ASME Standard B16.1 for Classes 125
and 250 Cast Iron Flanges. Face-to-face dimensions comply with the

• Valve designed for steam applications that operate between 100 and
250 psig.
• The Stop-Check feature of this valve requires a minimum of 50 psi
pressure differential between piping system and boiler to operate
properly.
• For installation between boilers suppling the same steam header, and
positioned with pressure under the disc. Straightway is for horizontal
or vertical line with upward flow. Angle valves are for "horizontaldownward" or "upward-horizontal" flow.
• These valves will perform the four following important functions:
1. Act as an automatic-non return valve applied as a containment device
to prevent gross backflow of steam from main header to boiler in case
the boiler fails.
2. Assist in cutting out boiler, when ceasing to fire. In this case, valve disc
automatically closes to restrict backflow of steam to the boiler.
3. Assist in returning boiler after a shutdown.
4. Restricts backflow of steam from header into boiler which has been
shut down and accidently opened. The check valve feature should not
be relied upon for primary shut-off.
• Cylindrical shaped disc is the only pressure-actuated part, light in
weight with ample guiding surface. It is specially designed to produce
a maximum lift at minimum velocities. There are no wing guides to
cause "spinning" with resultant rapid wear.
• Long throttling lip on disc retards flow when seating position is
approached. Disc chattering is prevented and wiredrawing of seating
surfaces is reduced.
• Flat Seats, accurately machined, facilitate true seating.
• Removable cast iron liner guides the disc throughout its full travel.
Being entirely independent of the body, it is not subject to distortion
by expansion strains.
• Piston Ring 6" and larger adds to dashpot's ability to avoid rapid disc
movements. Where pulsations are extremely severe, two rings can be
installed.
• Dashpot is self-contained in the liner. It provides an effective cushion
for the disc to prevent pipe line vibrations or hammering on the seat
at low velocities or on pulsating loads.
• Flanges conform to ASME B16.1. Flanges have 1/16" raised face with
concentric grooves.
• The body has integral bosses for drain connections. The bosses are
tapped and plugged.
• Determining the proper valve size needed is important. The size of a
stop check valve should be based on the boiler capacity and steam
flow through the valve, rather than on the size of the boiler outlet or
existing piping.

• Valve designed for steam applications that operate between 100 and
250 psig.
• The Stop-Check feature of this valve requires a minimum of 50 psi
pressure differential between piping system and boiler to operate
properly.
• For installation between boilers suppling the same steam header, and
positioned with pressure under the disc. Straightway is for horizontal
or vertical line with upward flow. Angle valves are for "horizontaldownward" or "upward-horizontal" flow.
• These valves will perform the four following important functions:
1. Act as an automatic-non return valve applied as a containment device
to prevent gross backflow of steam from main header to boiler in case
the boiler fails.
2. Assist in cutting out boiler, when ceasing to fire. In this case, valve
disc automatically closes to restrict backflow of steam to the boiler.
3. Assist in returning boiler after a shutdown.
4. Restricts backflow of steam from header into boiler which has been
shut down and accidently opened. The check valve feature should not
be relied upon for primary shut-off.
• Cylindrical shaped disc is the only pressure-actuated part, light in
weight with ample guiding surface. It is specially designed to produce
a maximum lift at minimum velocities. There are no wing guides to
cause "spinning" with resultant rapid wear.
• Long throttling lip on disc retards flow when seating position is
approached. Disc chattering is prevented and wiredrawing of seating
surfaces is reduced.
• Flat Seats, accurately machined, facilitate true seating.
• Removable cast iron liner guides the disc throughout its full travel.
Being entirely independent of the body, it is not subject to distortion
by expansion strains.
• Piston Ring 6" and larger adds to dashpot's ability to avoid rapid disc
movements. Where pulsations are extremely severe, two rings can be
installed.
• Dashpot is self-contained in the liner. It provides an effective cushion
for the disc to prevent pipe line vibrations or hammering on the seat
at low velocities or on pulsating loads.
• Flanges conform to ASME B16.1. Flanges have 1/16" raised face with
concentric grooves.
• The body has integral bosses for drain connections. The bosses are
tapped and plugged.
• Determining the proper valve size needed is important. The size of a
stop check valve should be based on the boiler capacity and steam
flow through the valve, rather than on the size of the boiler outlet or
existing piping.

Y-Pattern Stop Check Valve
Selecting the Proper Size –
Determining Pressure Drop
Since stop-check valves have a floating disc member, it is important the valve
be sized to provide full disc lift under flow conditions prevailing during the
major portion of the service life. If the valve is too large, the disc will float in a
partially open position and may cause fluttering of the disc and rapid wear.
2. From that point, draw another line through the valve size, for example
the 8-inch size, and establish a point on Index 2. Now move horizontally
to the diagonal pressure drop line on the right side. Where these lines
intersect, the pressure drop is 7.5 psi for the 8-inch, Class 250 globe
valve and 8.5 psi for the 8-inch Class 250 angle valve.
Conversely, if the valve is too small, pressure drop will be excessive.
The chart on the following page is a graphic presentation of flow data
determined by test. Its use offers a simple method of determining the best
size stop-check valve, as well as the pressure drop under varying conditions
of flow, without any computation.
Chart solutions resulting in a point on Index 2 that falls below the Line A-A
for Class 250 valves indicate the disc will not be fully lifted under the flow
conditions used. Operation under such conditions is not recommended but,
at times, must be tolerated for short periods during the low loads.
3. Enter the chart where Line A-A intersects Index 2 for Class 250 valves.
Move diagonally upward through the size being investigated (8-inch) and
establish a second point on Index 1. From this point, extend a line to the
specific volume established in Step 1 and at its intersection with the flow
rate line, read 48,000 Lb/H as the minimum flow rate at which the disc
will be in the fully lifted position. The pressure drop at this flow rate is
1.9 psi for globe and 2.1 psi for angle valves.
How to Use the Chart
Shown on the Following Page
Given: Steam Pressure-Temperature...250 psig 450°F
Flow Rate...Typical Daily Demand Curve
Typical Daily Load-Demand Curve
4. Repeat Steps 2 and 3 for other possible valve sizes, tabulate results, and
make size selection on basis of pressure drop and duration of partial disc
lift considerations.

Find: Valve Catalog No. and the best size for above installation.
Solution:
1. Enter the Temperature chart at 450 °F. Move vertically upward to the
curved line for 250 psi, then horizontally to the right to establish a
point on the specific volume scale. From this point, draw a line through
the flow rate being investigated (100,000 Lb/H) and establish a point
on Index 1.

Dotted lines on Demand Curve indicate minimum flow rates for wide open
8" and 10" valves.
5. The best choice for this example would be the 10" size because pressure
drop is much lower and duration of partially lifted disc is only slightly
greater than for the 8" size.
6. Pressure drop for any intermediate flow condition can be determined as
outlined in Steps 1 and 2.
7. Valves require a minimum of 50 psi differential pressure to seat the
valve.
