Wafer high performance butterfly valve

high performance butterfly valve

Wafer high performance butterfly valve provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases the valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.

Disc:                  ASTM A536 65-45-12, WCB, CF8M
Seat:                   RPTFE,SS316+RPTFE,SS316
Connection:      Wafer
Size                      3″-24″
Pressure:            Class150,Class300
Flange standard: ASME B16.5 Class150,Class300; EN1092 PN16, PN25, PN40
