Butterfly valve contain self-cleaning, suitable for the regulation of suspended particles in the fluid and thick, turbid fluid paste, also used in fields of large diameter, large flow, low pressure difference. Simple structure, convenient operation, light weight, large diameter. Widely used in power station, chemical, petroleum, papermaking industrial process for automatic regulation and remote control

Structure principle

Pneumatic butterfly valve, made up of ZMW(with hand wheel) or ZMA(without hand wheel) pneumatic actuator and butterfly valve, connected by connecting rod

Electric butterfly valve, made up of DKJ electric actuator and butterfly valve, connected by connecting rod, also can be direct connected with flange. Air on(power on) type, is that when be with signal, valve plate open, indicate with ”K” . when air off(power off), then negative, indicate with “B”
