VLV GATE RF 150# 316 6". BB TRIM 12 CF8M
Stainless steel gate valves are utilized in the chemical, petrochemical, oil & gas, food, paper, and pharmaceutical processing industries worldwide. This valve is manufactured with a forged body construction suitable for Class 150 service, with a 6-inch size. Shell materials are in accordance with ASTM A351 Grade CF8M, with other stainless steel grades available upon request. Stainless steel valves are designed and manufactured in conformity with API, ANSI, BS, and other recognized standards, ensuring quality that meets the stringent requirements of industrial applications.
Design Features:
-
The valve incorporates an H-shaped flexible wedge for sizes 3" and larger in Class 150 service.
-
The H-shaped wedge provides mechanical flexibility, ensuring secure contact with the body seat, reducing seat wear, lowering operating torque, and achieving a tighter closure.
-
This design is particularly important for large gate valves operating under high pressure and temperature, where temporary deformation may occur.
End Connections:
-
R.F. Flanged Ends to ASME B16.5
-
B.W. Ends to ASME B16.25
-
R.T.J. Flanged Ends to ASME B16.5
