The New Concert For Matal Seated Valve

  • This product is of heavy load designed for high pressure flow application.
  • Excellent durability of seats area and low operating torque by non-rubbing characteristic with triple offset construction.
  • Achieved bi-directional zero leakage service by the action of resilient metal seal and torque seating.
  • The seat rings both of body and disc are solid and real metal, can’t be finished away as lamellar seat.

Design Features

Soft Seated(-45°C~+180°C)

The RTFE seat ring is well-suited for extremely corrosive chemical solutions and high-temperature fluids of up to +210°C .

APPLICATIONS
Pharmaceuticals, water, jet fuel, Saturated steam, chlorine, ammonia, natural gas vacuum, oxygen, nitrogen, air-conditioning chilled, exhaust gas, town gas, hot water.
Abrasives, suspended solids, scaling mediums

Metal Seated(up to 450°C)

The metal seat ring allows control of extremely high-temperature fluids, thereby replacing conventional gate valves, and ball valves.

APPLICATIONS
High temperature, low temperature, abrasives, fly ash, slurries, steam, air, combustion gas, exhaust gas, netroten gas, sulfurousacid gas.

Fire Seated(-45°C~+210°C)

PTFE-metal-seat system
- Bidirectional sealing and fire safe design.

Bidirectional
- The primary PTFE : seat ring will be replenished with a secondary metal back-up ring. This metal seat provides a mechanical load to energies the PTFE-seat. In combination with the line pressure a bidirectional sealing against the design pressure is obtained.

Fire safe design
- After a fire, when the PTFE-seat ring has burned away, the secondary metal seat gives bidirectional sealing. This sealing systems meets the fire test requirement

APPLICATIONS
Fire-safe installations, abrasives, slurries, steam

Operations
The following operation of the valves are possible, the choice is depending upon the valve location and the type of work and service for which the valve is used.

Bare stem type valve only valve with gear operated valve with pneumatic actuator
valve with 10position lever operated valve with electric actuator valve with hydraulic actuator
