40 Inch Wedge Gate Valve, API 600, ASTM A216 WCB, 300 LB, RF

This 40-inch (DN1000) flexible wedge gate valve from a leading China manufacturer is built to API 600 standards and features a durable ASTM A216 WCB carbon steel body. Designed for high-pressure applications, it is rated for Class 300 LB (PN50) and comes with RF flanged ends for secure, leak-resistant connections. The flexible wedge design ensures tight sealing even under varying temperature and pressure conditions, while the handwheel operation allows for reliable manual control in large-diameter pipelines.

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