Design
VERVO 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.
Ranges 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.
Available Modifications For VERVO Steel Valves
Trim changes End connection modifications Packing and gasket changes Operator mounting Handwheel extensions |
Pressure equalizing By-pass Customer specified coatings Weld end bore changes Oxygen & chlorine cleaning & packaging |
A)Operation Large handwheels for easy operation. alsoavaliable 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 maintenance periods by requiring less stments. Belleville springs are employed to provide constant packing gland stress. |
C)OS&Y Outside screw and yoke. Cast steel globe valve yoke integral with bonnet for 10 & and smaller. |
||
D)BB 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 leak-off fitting connection and double packing stack is optionally avaliable for critical services |
H)Body-to-Bonnet Joint A flat face gasket joint is used in the 150lb valves. A male and female joint is used in 300lb to 600lb valves.ring joint is used in the body to bonnet connections in 900lb & higher rated valves. |
I)Disc Plug disc is stem guided on all 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 Ring Separate heavy duty, full ported rings for easy maintenance. Screwed or welded connection into body. |
