Cast steel globe valves are designed and manufactured to provide maximum service life and dependability. All globe valve are full ported and meet the design requirements of American Petroleum Institute standard API600& 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34 .Valves are available in a complete range of body/bonnet materials and trims.
- Trim changes
- End connection modifications
- Packing and gasket changes
- Operator mounting
- Handwheel extensions
Ranger of Materials
Standard body/bonnet materials include nine grades of carbon, low alloy and stainless steel, for special applications they can be supplied in other grades of alloy and stainless steel, there’s a full range of trim materials to match any service optional packing and gasket materials are available for a full range of service conditions.
- Pressure equalizing
- Customer specified coatings
- Weld end bore changes
- Oxygen & chlorine cleaning & packaging
Large handwheels for easy operation. Also available with gearing, motor actuators, pneumatic or hydraulic actuators for more difficult services.
B Live Load Packing
In services requiring frequent cycling or with high pressure/ temperature variations, live loading extends the service life between maintenanceperiods packing gland adjustments. Belleville spring are employed to provide constant
C OS & Y
Outside screw and yoke. Cast steel globe valve yoke integral with bonnet for 10 & and smaller.
Bolted bonnet welding bonnet and pressure seal bonnet in services requiring frequent cycling or with high pressure/ temperature variations.
E End Connections
A choice of flanged, RTJ flanged or buttwelding end for piping flexibility.
F Yoke sleeve
Furnished in aluminum bronze to reduce operating torque. Most size furnished with ball bearing yoke sleeves.
G Lantern Ring And Double Packing Set
Lantern ring with leak-off fitting connection and double packing stack is optionally available for critical services.
H Body-to-Bonnet Joint
A male and female joint or tongue and groove joint is used 150Lb to 600Lb valves, ring joint is used in the body to bonnet connection in 900Lb&higher rated valves. Body-to-Bonnet Joint
Plug disc is stem guided on al l size. Disc has a differential angle front the seat to provide a line contact for maximum sealing. The bottom of v-port disc is fuided by the body seat ring for maximum disc stability in throttling applications, the soft teflon ring is excellent for lower temperature service where tight shut off required.
J Seat Rings
Separate heavy duty, full ported rings for easy maintenance. Screwed or welded connection into body.
