Belleville disc springs are an important design component and serve a critical purpose in various types of flow control valves.

The production team at Belleville International is continually involved in the manufacturing of specialty bellevilles used to provide seating pressure for a wide size of range severe service and zero leakage ball valves.  Our products are found throughout the world in nuclear and other power generation facilities as well as within petroleum refining and petrochemical production facilities.

Stacked arrangements of smaller diameter Belleville spring washers are used to “live-load” valve stems and glands. The stored spring force compensates for valve packing wear, helping to reduce potentially dangerous leaks and emissions thus maintaining the valve’s operating efficiency while reducing maintenance costs.  We also produce other valve components such as body seals and seat locking rings and will quote on similar components you may need to outsource.
