The China Class 2500 LB Globe Valve Factory specializes in manufacturing high-pressure valves that adhere to the ASME B16.34 standard. These valves are crafted from cast carbon steel, specifically ASTM A216 WCB, ensuring exceptional strength and durability. With a 6-inch size (DN150) and a pressure rating of Class 2500 LB (PN420), they are designed for high-pressure applications. The valves feature RTJ (Ring-Type Joint) flanged ends for secure and leak-tight connections. They are operated by a bevel gear mechanism, providing smooth and reliable operation.

The Cast Steel Globe Valves are meticulously designed and manufactured to achieve an exceptionally low leakage rate of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). To ensure this level of performance, extensive baseline laboratory testing, including both static and cycle tests, has been conducted. This testing has established the critical design parameters required to achieve low-emission sealing in both the stem packing seal area and the bonnet gasket sealing area. Additionally, an in-house testing procedure has been developed and is regularly executed to confirm that the standard product design and manufacturing criteria consistently result in Cast Steel Globe Valves meeting the maximum VOC leakage limit of 100 ppm prior to shipment.
