Full-Port Design:
Eliminates flow turbulence and energy loss, ideal for oil, gas, and water transmission pipelines.
Wedge gates (flexible, solid, or split) compensate for thermal expansion and seat wear.

Robust Sealing Performance:
Parallel or tapered sealing faces (metal-to-metal or resilient seated) for leak-proof operation up to ASME Class 2500.
Bi-directional sealing capability for versatile installation.

Industrial Durability:
Bodies in cast steel (WCB/WCC), stainless steel (CF8M/CF8), or alloy steel (WC6/WC9).
Compliant with API 600/603 standards for refinery, petrochemical, and power generation applications.

Common Applications:

• Oil & Gas: Crude oil trunk lines, wellhead isolation.
• Water Treatment: Mainline shutoff in distribution networks.
• Steam Systems: Boiler isolation, turbine bypass control.
