Valves shall meet the requirements of MSS SP-68, High Pressure Butterfly Valves with Offset Design. hard seal butterfly valve suitable for bi-directional end of line service (dead end) at full rated pressure, . ANSI Class 150 or 300, Carbon Steel Body, Stainless Steel Disc, Stainless Steel or Duplex Steel Stem, PTFE or Graphite Seals. Permanently lubricated bearings of 316 Stainless Steel with Graphite.

Butterfly valve is a kind of valve that uses disc type opening and closing parts to rotate about 90 ° to open, close or regulate medium flow.

Butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, simple and rapid in

operation, but also has good flow regulation function and closing sealing characteristics at the same time. It is one of the fastest developing valve varieties in the past ten years. Butterfly valves are widely used. The variety and quantity of its use is still expanding, and it is developing to high temperature, high pressure, large diameter, high sealing, long life, excellent regulating characteristics, and multi-function of one valve. Its reliability and other performance indexes have reached a high level performance.
