ASME B16.34 Globe Valves, BS 1873, A216 WCB, 4 Inch, 300 LB

The ASME B16.34 Globe Valves Factory in China produces high-quality globe valves adhering to BS 1873 standards. These valves are made from cast carbon steel ASTM A216 WCB, ensuring durability and reliability. The 4-inch (DN100) valves are rated for Class 300 LB (PN50) and feature RF flanged ends for secure and easy connections. They are manually operated, providing precise control over fluid flow.

Cast Steel Globe 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, including static and cycle testing, has been conducted to establish the critical design parameters necessary to achieve low emission sealing in the stem packing seal area and 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 Cast Steel Globe Valves meeting a maximum VOC leakage of 100 ppm prior to shipment.
