1/2" 316 STAINLESS STEEL GATE VALVE BB RF CLASS150 TR12
Stainless steel valve are utilized in the chemical, petrochemical, food, paper, and pharmaceutical processing industries all over the world. Investment casting shall be manufactured up to 1 1/2" for class 150 and 300. Shell materials shall be in accordance with ASTM A351 Grade CF8M & CF8 and the others are optional. Stainless steel valve are designed and manufactured in conformity with API, ANSI, BS and other standards recognized with quality meeting the stringent requirements for such industrial applications. Stainless steel valve are specialized products through the processes of design, material selection, manufacturing, quality control, and experiences to final product.
Investment casting shall be manufactured up to 1 1/2" for class 150 and 300.
Shell materials shall be in accordance with ASTM A351 Grade CF8M & CF8 and the others are optional.
- PK adopts an H-shaped flexible wedge of which the size is 3" and larger for Class 150 and 2" and higher for Class 300/600.
- The H-shaped flexible wedges are featured with mechanical flexibility to be able to adjust to the shape of body seat for secure mutual contacts.
- It has a particular importance when large gate valve is applied to extremely high pressure and temperature that temporary deformation may occur in valve all the time.
- If the H-shape wedge is provided, operating torque would get smaller, seat wear less, and valve closing tighter.
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
