Disc Springs for Valves

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.
Disc springs are the key part to fix Ball Valve, its performance will
directly affect the sealing effect of the valve.
When we design and manufacture Disc Springs for Ball Valves, we should pay
attention to the following points.
