API 600 Gate Valves, ASTM A216 WCB, 12 IN, 300 LB, DN300, RF

The API 600 Gate Valves Factory in China specializes in producing high-quality gate valves designed to meet stringent industry standards. These valves feature a cast carbon steel body made from ASTM A216 WCB material, ensuring durability and reliability. With a 12-inch diameter (DN300) and a pressure rating of Class 300 LB (PN50), they are engineered for robust performance in demanding applications. The valves are equipped with a gearbox-operated mechanism for smooth and efficient operation, and they come with raised face (RF) flanged ends for secure and leak-free connections.

Cast Steel Gate Valves are engineered to limit volatile organic compound (VOC) emissions to under 100 parts per million (ppm). Comprehensive baseline laboratory tests, including both static and cycle evaluations, have been conducted to pinpoint the crucial design parameters required for achieving low-emission sealing in both the stem packing and bonnet gasket areas. Additionally, an in-house testing protocol has been established and is regularly executed to verify that the standard design and manufacturing processes consistently yield valves with VOC leakage below 100 ppm before they are shipped.
