High quality electrical butterfly valve Product introduction

 High quality electrical butterfly valve turns multi-turn rotational motion into partial rotational motion (90°±5%) through reducer by electromotor. Provided with features of starting and closing steadily, large output torque, and the labor intensity of the operator can be greatly reduced, Especial for high pressure, heavy caliber Valves; It is suitable for being installed at the place can not be manual manipulation or hard to access, the Electric wafer butterfly valves are unlimited by height of installation, easy for remote control, make for the overall system automation; power source could be obtained easier than pneumatic or hydraulic source, the establish of electric wire is simpler than pneumatic or hydraulic line. But the structure is complicated, should be taken protection against the moisture and explosion. Normally used in the environment temperature under 50℃, and the relative humidity less than 80%.
