Twin seal plug valve manufacturers in India

Speciality Valve is a leading Twin seal plug valve manufacturers in India, providing top-quality valves for zero-leakage performance in high-temperature and high-pressure operations. Our valves are carefully designed to provide excellent sealing, long lifespan, and reduced maintenance, which suit them for applications in various industries.

What is it?

A twin seal plug valve is a double-block and bleed valve that gives a positive shut-off in each flow direction. It employs a plug with two sealing elements that isolate both the upstream and downstream sides, creating a tight seal and enabling safe bleeding of the cavity.

Why Required?

Twin seal plug valves play a vital role in applications requiring absolute shut-off and zero leakage. They make it unnecessary to have individual isolation and bleed valves, thus making the piping system simpler. They are vital in safety-critical operations like pipeline maintenance, tank storage, and chemical processing.

Major Components of Twin Seal Plug Valve:

Valve Body: Constructed from long-lasting materials such as carbon steel, stainless steel, or alloy steel for corrosion and pressure resistance.

Plug: Central revolving component with two metal or resilient seats for sealing.

Seals/Seats: Shut-off bubble-tight on each side.

Bleed Port: Enables safe venting or draining of the central cavity.

Actuator or Handwheel: For hand or automatic operation.

Working of Twin Seal Plug Valve:

As the plug is turned, it will be in alignment with the ports of the valve to permit flow. In a closed position, the twin seal surfaces are against the seats closing off both the inlet and the outlet sides. The seal cavity can be bled through the bleed port so that the total isolation can be checked.
