High Temperature Hot Air Metallurgy Damper Butterfly Valve

High Temperature Hot Air Metallurgy Damper Butterfly Valve 

The opening and closing part of High Temperature Hot Air Metallurgy Damper 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 disc, worm gear box should be installed on the valve rod. The use of worm gear reducer can not only make the butterfly disc have self-locking ability, make the butterfly disc stop at any position, but also improve the operation performance of the valve. 

High Temperature Hot Air Metallurgy Damper Butterfly Valve  has the characteristics of high temperature resistance, high pressure range and large nominal diameter. The valve body is made of stainless steel, and the sealing ring of valve plate adopts 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.
