ASTM A217 WC6 Wedge Gate Valve, API 600, 16 IN, CL600, OS&Y

The ASTM A217 WC6 Wedge Gate Valve Plant produces high-performance wedge gate valves designed in accordance with API 600 standards. These valves feature an alloy steel body, providing excellent strength and durability. With a 16-inch diameter (DN400) and a pressure class of 600 LB (PN100), they are suitable for demanding industrial applications. The outside screw and yoke (OS&Y) design allows for easy operation and maintenance. The raised face (RF) flanged ends ensure secure and reliable connections, making these valves ideal for critical systems requiring high reliability and performance.

Cast Steel Gate Valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). Extensive baseline laboratory testing—both static and cycle testing—has been conducted to establish the critical design parameters required to achieve low-emission sealing in the stem packing area and bonnet gasket area. An in-house testing procedure has been developed and is regularly performed to ensure that the standard product design and manufacturing criteria consistently result in Cast Steel Gate Valves meeting a maximum of 100 ppm VOC leakage prior to shipment.
