Shanghai Hegong Disc Spring Manufacture Co.,Ltd

Disc Springs for Valves, also be known as Belleville Springs for Valves, Belleville Washers for Valves ... Disc springs are widely used in various types of valves such as Ball Valves, Regulating Valves, Globe Valves, Pigging Valves, and Sea Valves. The load of Disc Springs is large with small deflection, they can provide sufficient valve seat sealing force.
The role of the Disc Spring inside the valve is to maintain sufficient contact pressure on the joint. Using Hegong Disc Springs Stacks either in series or parallel, obtain the required force and stroke, to meet the needs of each valve. Disc Springs Stacks apply a pressure and absorb the contraction and expansion that may occur due to pressure, temperature, or relaxation.
Depending on the working environment, Belleville Springs for Valves can be produced by material such as Inconel750, Inconel718, 17-7PH. These materials have good corrosion resistance and high temperature resistance, can also provide adaptable working loads under harsh conditions and high temperature environments.
