Maximize Recovery. Not Same Day. Now.

Weco ULT and DR plug valves are premium, quarter-turn valves designed for a wide range of standard and sour gas drilling, production, and well-servicing applications. These rugged valves are offered in single and dual-body designs in pressures to 20,000 psi. They range in size from 1 to 4-inches and come with threaded, Weco wing union, flanged, and clamp hub ends. Consult factory for configurations. Like all pressure containing products, Weco plug valves require special handling.

ULT Plug Valves-Benefits:

• Ultimate Seal-ability
  The key to the ULT plug valve’s unprecedented seal integrity is its proprietary floating plug and dual-seal design. When the valve is closed, the dual segment seal provides a redundant seal on the downstream side of the valve.

• Ultimate Valve Body Life
  When a ULT 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 the ULT plug valve, by forcing flow between the plug and segment interface, eliminates problem which is extrusion damage to the upstream and downstream segment seals.

• Ultimate Life Cycle Cost Savings
  Superior sealability, increased life of valve body, and elimi­nation of premature seal damage result in significant savings in life cycle costs of the ULT plug valve over traditional plug valves.
