motorized butterfly valve for power plant

Minimum Order

Electric actuator regulating telescopic butterfly valve

It is consist of pneumatic actuators and telescopic butterfly valve, they supporting using with solenoid valve, pressure reducing valves (the air dealing parts), accept the 0-20madc voltage control signal, medium in the pipeline could be properly control



The products is using in the working conditions of medium like general corrosion , no corrosive gas, liquid suspending liquid medium for intercepting and adjusting control, also can make the old pipeline renovation, maintenance and supporting use valve




Application of the industry:

chemical industry 

oil refining industry

pesticide industry

Water conservancy industry

Municipal industry
