3. Length of extended bonnet/stem according to Shell standard or upon request
4. Floating ball and trunnion mounted ball type are for option
Standard
Design and manufacture to API 6D, BS 5351, API 608
Face to face to API 6D or ASME B 16.10
Flange Ends to B 16.5
Test and Inspection to API 6D or API 598
Metal Seated Ball Valve
Features
1. Maximum temperature: 400℃
2. Low pressure reliable sealing
The metal to metal ball valve adopts spring seat structure, which can push upstream seat tightly against the ball surface creating a reliable seal even if extremely low pressure.
3. Valve stuck under high temperature prevented
In case of high temperature working condition, the valve seat and ball would possibly get stuck due to heat expansion, and the valve could not be open. Our metal to metal seated ball valves employ the design of beveling spring loading, which would absorb the heat expansion of parts caused by the beveling spring. Then, it is ensured that the valve would not get stuck and realize easily open and close in case of high temperature condition.
