Weco® Plug Valves

Back to Products

Weco sour gas plug valves are reliable, quarter-turn valves designed for services to 15,000 psi cold working pressure. These rigged valves range in size from 1 to 3 inches and come with integral Weco wing union ends. The union ends add considerable strength to connection, reduce turbulence, and minimize corrosion and stress concentration sites. Weco sour gas plug valves are available with manual, handwheel, and hydraulic actuators.

Model DR Plug Valves
  • Floating segments insure positive seal

    Dual seal segments float slightly to offset possible micro-expansion of the valve body and to insure a positive seal in sour gas applications.

  • Easy operation under pressure

    The cylindrical plug fits between a set of precision machined seal and side segments for ultra low operating torque under pressure.

 

Model ULT Plug Valves
  • Exclusive patented seal design extends service life

    Seal design forces line fluid between the plug/seal interface when the valve is closed to eliminate body erosion and limit wear to replaceable components, extending service life 3 to 5 times over other plug valves while reducing maintenance costs.

  • Two-piece floating plug/stem

    FMC’s proprietary floating plug and stem uniformly distribute load against the downstream seat to improve sealing and reduce operating torque.

  • Bottom entry for fast, easy repair

    The Model ULT valve features bottom entry design for ease of inspection and repair without removal of operator or actuator.
