Flexible Wedge Gate Valves

Flexible wedge gate valve is a key valve widely used under the American standard system. Its core is to add elastic structure design on the basis of traditional rigid gate to solve the problems of high temperature deformation, jamming and sealing compensation.

Features:
Reliable sealing performance: The flexible wedge gate increases the auxiliary sealing load through the wedging action, ensuring good sealing effect under both high and low pressure conditions.
Long service life: The sealing surface is made of stainless steel and carbide materials, which has a long service life.
Light and flexible operation: The use of flexible graphite filler ensures the lightness and flexibility of the valve operation.
Various drive modes: Supports manual, electric, pneumatic and gear transmission and other drive modes.
Wide range of application: Widely used in oil and steam pipelines in petrochemical, thermal power plants, etc., suitable for harsh working conditions such as high temperature and high pressure, low noise, cavitation and vaporization.

 Advantages ‌
‌High temperature anti-stuck ‌
The elastic gate can absorb thermal expansion deformation and avoid the gate from getting stuck in the valve seat under 425℃ working conditions.
‌Seal self-compensation ‌
The annular groove provides elastic preload to automatically compensate for valve seat wear or processing errors.
‌Low operating torque ‌
Elastic contact reduces friction, and the opening and closing torque is ≈30% lower than that of rigid gate valves.
‌Long life design ‌
The carbide sealing surface is erosion-resistant, and the service life is increased by more than 50% compared with traditional gate valves.
