Electric butterfly valve

Electric motorized butterfly valve introduction

Electric motorized butterfly valve is composed of butterfly valve and on-off type, regularing type or intelligent type electric actuator with voltage AC110V AC220V AC380V or others.
Specific categories of electric motorized butterfly valves are: stainless steel 
electric motorized butterfly valve,carbon steel electric motorized butterfly valve, PTFE FEP PFA lined electric motorized butterfly valve,Flanged end electric motorized butterfly valve,Wafer end electric motorized butterfly valve,Lug end electric motorized butterfly valve,concentric electric motorized butterfly valve,eccentric electric motorized butterfly valve and other butterfly valves.

Electric 
motorized butterfly valve can according to the sealing performance into metal seal and soft seal with compact structure、small volume、reliable operation、good sealing、easy maintenance installation convenient and the adoptability is strong advantages. Electric motorized butterfly valve can be widely used in petroleum、chemical industrylight industry、papermaking industrial、pharmaceutical、car automatic control system on a remote concentrated or local control.

Electric motorized butterfly valve working principle

Electric motorized butterfly valve is composed of an electric actuator and a soft seal or metal seal butterfly valve. The butterfly valve is opened or closed by the power drive of the electric actuator. The butterfly valve stem drives the disc to rotate back and forth within the range of 0-90 degrees.It can also be assembled according to the working conditions of intelligent multi-rotary electric actuators or intelligent regulating actuators can realize unlimited automatic switch of butterfly valve disc and arbitrary adjustment of butterfly valve butterfly disc opening size, so as to control the temperature, flow, pressure, liquid level and other parameters control.
