GS-C25 Wedge Gate Valve, DIN 3352, DN200, PN16, Bolted Bonnet

The GS-C25 Wedge Gate Valve Plant in China specializes in producing high-quality wedge gate valves that meet DIN 3352 standards. These valves feature a carbon steel body with a DN200 (8-inch) size and a PN16 pressure rating, equivalent to Class 150 LB. They are designed with a bolted bonnet, outside stem and yoke (OS&Y) mechanism, and a handwheel for easy operation. These features ensure reliable performance and durability, making them suitable for a wide range of industrial applications.

Wedge Gate Valves are engineered to meet stringent emission standards, ensuring leakage of volatile organic compounds (VOCs) remains below 100 ppm (parts per million). Extensive laboratory testing, including both static and cycle tests, has established critical design parameters to achieve low-emission sealing at the stem packing and bonnet gasket areas. An in-house testing procedure has been developed and is regularly conducted to ensure all valves meet design and manufacturing standards, guaranteeing VOC leakage does not exceed 100 ppm before shipment.
