Introduction video of Butterfly Valve : 

Butterfly valve is a valve that used disc-type butterfly plate reciprocates by 90 °to open,close or throttle the flow of media

GZP butterfly valves are manufactured and modified to the latest edition of API609,BS5155,ASME B 16.34 .And passed the fire resistance inspection standards of API 607, API6FA and BS6755.All valves from GZP valves are strictly 100% tested before shipment to guarantee zero leakage.

The range of GZP butterfly valve design is as follows:
1.Size : 2” ~ 96”   DN 50 ~DN 2400
2.Pressure : 150lb ~2500lb   PN6~PN420
3.Material : carbon steel , stainless steel ,etc and other special material.
           Especially in NACE standard 
4.Connection ends: ASME B 16.5 in raised face (RF),Flat face (FF) , Ring Type(RTJ) ,wafer and lug.
                  ASME B 16.25 in butt welding ends
5.Face to face dimensions :ASME B 16.10
6.Temperature : -29℃ to 425 ℃

GZP valves can be equipped with gear operator, pneumatic actuators, Hydraulic actuators, Electric actuators,bypasses,locking devices,chainwheels,extended stems and many others are available to meet the customers’ requirements.
