Wedge Gate Valve is a fundamental fluid control component widely utilized in pipelines carrying water, oil, and gas, with its design and performance adhering to core standards like API 600, API 6D, and ASME B16.34. Available in sizes ranging from 2″ to 60″ and pressure ratings of 150LB to 4500LB, Wedge Gate Valve accommodates design temperatures from -196℃ to 800℃, making it adaptable to extreme industrial environments. Its structural options, including solid disc, OS&Y, BB, and FB designs, paired with pressure seal and welded bonnet variants, enhance operational flexibility, while F-to-F dimensions comply with API 6D and ASME B16.10 to ensure pipeline compatibility. Wedge Gate Valve’s robust construction enables reliable on-off control, positioning it as a staple in oil and gas transmission and water treatment systems.
Wedge Gate Valve integrates seamlessly with Flexible Gate Valve, a variant engineered for improved sealing and adaptability to pipeline misalignment
Flexible Gate Valve shares the same size and pressure range as Wedge Gate Valve, adhering to API 6D and ASME B16.34 norms, and features a flexible gate design that compensates for minor pipeline deviations. This valve adopts compatible connection standards such as ASME B16.5 and RTJ, ensuring easy integration with existing Wedge Gate Valve systems, and excels in applications where pipeline stability is compromised, such as offshore and underground installations.
Wedge Gate Valve serves as the base for Flexible Wedge Gate Valve, a hybrid design that combines the wedge structure with flexible gate properties to optimize performance
Flexible Wedge Gate Valve retains the Wedge Gate Valve’s temperature range of -196℃ to 800℃ and pressure rating up to 4500LB, while its flexible wedge minimizes thermal expansion impacts and improves sealing under fluctuating pressure. It follows the same design norms as Wedge Gate Valve and offers BW and RTJ connections, making it suitable for high-temperature oil and gas pipelines where thermal cycling is common.
Wedge Gate Valve’s sealing capabilities are enhanced in Resilient Wedge Gate Valve, which incorporates a resilient seating material to achieve leak-tight performance
Resilient Wedge Gate Valve aligns with Wedge Gate Valve’s core specifications, including size range and API/ASME standards, and is particularly suited for water and low-pressure gas systems. Its resilient wedge design complements the Wedge Gate Valve’s structural integrity, preventing medium leakage and extending service life in municipal water supply and light industrial applications.

Wedge Gate Valve is commonly manufactured as Cast Steel Wedge Gate Valve, leveraging cast steel’s durability to meet high-pressure and high-temperature requirements
Cast Steel Wedge Gate Valve adheres to the same pressure rating (150LB~4500LB) and temperature range as standard Wedge Gate Valve, with connections complying with ASME B16.47 A&B and EN 1092. The cast steel construction enhances corrosion resistance and mechanical strength, making Cast Steel Wedge Gate Valve ideal for harsh oil, gas, and petrochemical environments where reliability under extreme conditions is critical.
In summary, Wedge Gate Valve is the cornerstone of the product series, with its versatile specifications and compliance with global standards influencing all variants. Flexible Gate Valve, Flexible Wedge Gate Valve, Resilient Wedge Gate Valve, and Cast Steel Wedge Gate Valve all inherit the core parameters of Wedge Gate Valve while adapting to specific operational needs. From pipeline alignment compensation to leak-tight sealing and extreme condition resistance, these valves cater to diverse water, oil, and gas applications. Their adherence to unified design norms ensures interchangeability and reliability, solidifying their role as essential fluid control components in industrial pipelines worldwide.
