Jacketed Gate Valve, API 600, ASTM A351 CF8, 3 IN, CL300, BW

This Jacketed Wedge Gate Valve is built to ANSI B16.34 and API 600 standards, offering robust flow control for process systems requiring thermal insulation. Constructed from cast stainless steel ASTM A351 CF8, it comes in a 3-inch (DN80) size with a pressure rating of Class 300 LB (PN50). Designed with butt weld ends for secure, leak-proof connections, the jacketed body allows for efficient media temperature maintenance, making it ideal for viscous or temperature-sensitive fluids.

Cast Steel Gate Valves are engineered to ensure VOC (volatile organic compound) leakage of less than 100 ppm (parts per million). This performance is achieved through extensive baseline laboratory testing—including static and cycle testing—which has helped define the critical design parameters necessary for low-emission sealing at both the stem packing and bonnet gasket areas. KOSEN also implements an in-house testing procedure that is periodically performed to confirm that each valve consistently meets the 100 ppm VOC leakage standard before shipment.
