OUWEI VENTILATION BUTTERFLY VALVE

◆ Product Overview
Ventilation butterfly valve with manual lever mechanism or electric actuator butterfly plate to the valve opening and closing,in the case of does not stop the fan to reduce to the blast furnace air supply,excess gas into the atmosphere.a short structure size,light weight,easy installation,etc.The valve drive torque is small,easy,easy to operate.Set on the valve body sealing ring,seal,no visible gap between leak rate is small.Between the butterfly plate and the valve body expansion gap is big,can effectively prevent because of heat bilges cold shrink card death phenomenon.This valve can be equipped with a variety of device drivers,such as manual gear,worm gear drive,pneumatic device and electric device.

◆Use
