ASTM A351 CF8 Globe Valves, ASME B16.34, 2 Inch, CL900, RTJ

The China ASTM A351 CF8 Globe Valves Factory produces high-quality valves in compliance with ASME B16.34 standards. These valves feature a stainless steel body made from ASTM A351 CF8 material, ensuring durability and corrosion resistance. With a 2-inch (DN50) diameter and a Class 900 LB pressure rating, equivalent to PN150, they are designed for demanding industrial applications. The valves have RTJ flanged ends for secure connections and are handwheel operated for easy control.

Cast Steel Globe Valves are engineered to ensure minimal leakage, with a target of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). Through extensive baseline laboratory testing, including both static and cycle testing, we have identified and optimized critical design parameters to achieve low emission sealing, specifically in the stem packing and bonnet gasket sealing areas. We employ a rigorous in-house testing procedure, conducted periodically, to verify that each valve consistently meets the stringent 100 ppm VOC leakage standard before shipment, ensuring reliability and environmental compliance.
