Butterfly Valve:

 

 

 Butterfly Valves is closed parts (disc or disc) the disk around the valve axis to achieve the opening and closing a valve in the pipeline from the off and throttling the main use. Valve opening and closing is a disc-shaped piece of the disc, the valve body around its own axis of rotation, or adjustments to achieve the purpose of opening and closing. Valve fully open to fully closed is usually less than 90 °, Butterfly Valves and butterfly stroke itself is not self-locking capability, in order to position the disc to install the valve stem on the worm gear reducer. With worm reducer, not only can make the disc with self-locking capability, so that the disc stops at any position, but also to improve the operational performance of the valve.

 

 Industry-specific characteristics of butterfly Valves to high temperature, for higher pressure range, the valve nominal diameter of large, carbon steel valve body, valve plate rubber seal with metal ring instead of ring. Large-scale manufacture of high temperature valve welded with steel plate, the main medium for high-temperature air duct smoke and gas pipelines.
