Improvement of the hydraulic butterfly valve

Hydraulic butterfly valve early years of the safety shield, butterfly valve is actually a combination valve linkage, its structure is a disc valve and a vent valve.electric solenoid valve
The role of the damper is closed between the two valve with pressure residual gas through the vent let go, play a role in ensuring safety.
Due to its special importance, are known as "safety butterfly valve, the valve directly affects the reliability of production safety. The tightness and reliability requirements must have original design defects in the high failure rate.air cylinder manufacturers
Easily out of stock, broken off, the trip is not enough, loose relationship. The problem is that the original design of the main disc axis is the two axle fixed on both sides of the disc, the structural strength of the result of a lack of high failure rate. Often appear normal external part of the work, the disc does not move air into the furnace, and the reason is not easy to find.pilot valves
