The triple offset butterfly valve is used in industrial pipelines such as metallurgy, electric power, petrochemical, water supply and drainage, and municipal construction. Its high-grade alloy and advanced design allow it to withstand various temperature fluctuations, corrosion resistance, and pressure management.Learn more:shiphamvalves.com
The Geometric Design of the Sealing Components
Triple-offset butterfly valves offer several advantages over conventional valve types. They feature a geometry design that makes the disc and seat conform to each other to ensure an effective seal and a low operating torque. This reduces wear and extends the life of the valve.
In contrast to other valve types, the geometry of triple-offset valves allows the seat to contact the disc only at the very end of the stroking cycle. This minimizes the impact of tiny solid particles in the medium and prevents seal surface bite caused by thermal expansion. In addition, it also protects the valve body from damage and extends its service life.
Triple eccentric valves also have an oblique sealing arrangement that provides a bubble-tight shutoff in high-pressure and high-temperature applications. This is a significant advantage over other types of valves that use friction in the sealing mechanism, which may deteriorate due to the high temperature or corrosive media.
In addition to this, triple eccentric butterfly valves are designed with a seat that can be replaced without disassembling the valve. This eliminates the need to transport the entire valve to a factory and significantly reduces maintenance costs.
