Bellows Sealed Gate Valves, DIN 3352, A216 WCB, DN80, PN25

The Bellows Sealed Gate Valves Manufacturer produces high-performance valves designed according to DIN 3352 standards. These valves feature a cast carbon steel body made from ASTM A216 WCB material, ensuring robustness and durability. With a DN80 (3-inch) size and a pressure rating of PN25 (Class 300 LB), they are suitable for demanding industrial applications. The valves are equipped with RF (Raised Face) flanged ends for secure and reliable connections. They are manually operated via a handwheel, providing easy control.

Wedge Gate Valves are engineered and produced to guarantee volatile organic compound (VOC) leakage below 100 ppm (parts per million). Extensive baseline laboratory testing, including both static and cycle tests, has established essential design parameters to achieve effective low-emission sealing in the stem packing and bonnet gasket areas. Additionally, a rigorous in-house testing procedure is regularly conducted to ensure that the standard design and manufacturing processes consistently deliver Wedge Gate Valves with VOC leakage not exceeding 100 ppm before shipment.
