Electric high temperature Ventilation Butterfly Valve

Electric Control Smoke Damper

The High temperature ventilation butterfly valve refers to a kind of valve whose closing part (disc or disc) is a disc and rotates around the valve shaft to open and close. It is mainly used for cutting off and throttling on the pipeline.

The opening and closing part of high temperature ventilation butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting. High temperature ventilation butterfly valve is usually less than 90 ° from full opening to full closing. Butterfly valve and butterfly rod have no self-locking ability. In order to locate the butterfly plate, worm gear reducer should be installed on the valve rod. The use of worm gear reducer can not only make the butterfly plate have self-locking ability, make the butterfly plate stop at any position, but also improve the operation performance of the valve.

The industrial high temperature ventilation butterfly valve is characterized by high temperature resistance, large nominal diameter, carbon steel valve body and metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, which is mainly used for flue gas duct and gas pipeline with high temperature medium.
