Value Elements

• In Stock and Ready to Ship
• GWC valves are stocked and ready to ship, helping reduce lead times on critical valve requirements. This makes them a strong fit for projects where availability, scheduling, and quick replacement matter.
• Proven API 6D Pipeline Valve Design
• The Model F & FF is designed for demanding pipeline and station applications, with API 6D construction and a trunnion-mounted design built for reliable isolation in natural gas transmission, distribution, and process applications.
• Wide Size and Pressure Class Range
• Available from 2" to 24" and ANSI Class 150 to 2500, this valve family can cover a broad range of station and pipeline requirements with one trusted product platform.
• Highly Configurable for Application Needs
• With full or reduced bore options, 2-piece or 3-piece body configurations, multiple body materials, and single or double piston effect seat designs, the GWC bolted body valve can be configured to suit a wide range of service conditions.
• Multiple Seat and Material Options
• Available in carbon, alloy, and stainless steel materials, the valve can be specified for general service, sour service, low-temperature applications, cryogenic service, abrasive service, and high-temperature applications.
• Built-In Safety and Reliability Features
• Standard features such as double block and bleed, spring-loaded seats, anti-blowout stem, anti-static device, fire-safe design, and NACE compliance help support safe, dependable performance in critical gas infrastructure.
• Flexible Actuation Options
• The trunnion-mounted design is well suited to manual, pneumatic, electric, or hydraulic actuation, making it a practical choice for both standard isolation service and automated station control.

Comparison vs. Next Best Alternative

• Stock Availability vs. Long Lead Times
• Many comparable API 6D trunnion valves are project-built or subject to longer manufacturing lead times. GWC’s stocked availability gives customers a faster path to delivery, replacement, and project completion.
• Widely Used, Approved, and Proven
• GWC bolted body valves are widely used across Canada and approved by many transmission and distribution companies, giving utilities and contractors confidence in a product that is already familiar in the market.
• Highly Customizable Without Moving to a Specialty Valve
• Instead of jumping to a custom-engineered valve for every application, the GWC Model F & FF offers a broad range of configurations, seats, materials, trims, and actuation options within a proven API 6D platform.
• Strong Fit for Low-Temperature Canadian Applications
• With low-temperature material and seat options available, the GWC bolted body valve is well suited for Canadian gas infrastructure where cold-weather performance is a key consideration.
• Reliable Isolation for Critical Stations
• Compared with lighter-duty floating ball valves, the trunnion-mounted design is better suited for larger sizes, higher pressures, and critical isolation points where lower operating torque, seat reliability, and actuation compatibility matter.

Where Do I Use This Product and Why?

• Transmission and Distribution Systems
• Use the GWC bolted body trunnion valve in natural gas transmission and distribution systems where a proven API 6D isolation valve is required.
• Small to Large City Gate Stations
• This valve is a strong fit for city gate stations where reliable shutoff, double block and bleed capability, and compatibility with actuation are important for safe operation and maintenance.
• Large District Stations
• For district stations with higher flow rates or higher pressure requirements, the trunnion-mounted design provides the strength, stability, and operating reliability needed for critical isolation service.
• Large Customer Receipt Points
• Use this valve at large customer receipt points where dependable isolation, pressure class flexibility, and utility-approved equipment are important.
• Pipelines, Pumping, and Compression Stations
• The Model F & FF is designed for pipeline, pumping, and compression station applications where full-port or reduced-port options, fire-safe construction, and API 6D compliance are required.
• Low-Temperature and Severe-Service Applications
• With configurable materials and seat options, the valve can be applied in low-temperature, cryogenic, abrasive, high-temperature, sour, or other demanding service conditions.
