Plug valves are made of high quality forged alloy steel with heat-treatment, and can provide dependable service for applications such as cementing, fracturing, acidizing, coiled tubing and sand control. Plug valves are premium, quarter-turn valves designed and come with threaded, Weco wing union, for plug valves with flanged ends, contact the manufacturer. plug valve consist of valve body, sealing segments, support sealing, plug, plug sealing, body cap, greasing fitting, handle, and etc., and can be available in three primary models in 1"×2", 2"×3" and 3", with cold working pressure range from 6,000 to 15,000 psi in both Standard and H2S service, plug valves are primary used as isolation valves and can isolate flow from either direction, different components or parts with deferent pressure ratings of plug valves cannot be mismatched, repair kits for plug valves are available, each plug valve is stamped with API monogram and tracing number.

Plug Valves Characteristics:

Ultimate Seal-ability

Plug valve’s ultimate seal integrity is its floating plug and dual-seal design, when plug valve is closed, the dual segment seal provides a redundant seal on the downstream side of the valve.

Ultimate Valve Body Life

When plug valve is closed, the only available flow path is between the seal segment and plug interface. This flow path eliminates body erosion and limits any potential wear to replaceable components.

Ultimate Seal Life

The dual-seal design of plug valve, by forcing flow between the plug and segment interface, eliminates problem which is extrusion damage to the upstream and downstream segment seals.
