DIN 3352 Wedge Gate Valves, GS-C25, DN200, PN40, RF Flanged

Our China DIN 3352 Gate Valves are designed for reliable on-off control in various industrial applications. These flexible wedge gate valves feature a carbon steel GS-C25 body, ensuring durability and strength. With a diameter of DN200 (8 inches) and a pressure rating of PN40 (Class 300 LB), they are suitable for high-pressure systems. The raised face (RF) flanged ends provide secure and leak-free connections. Manual operation via a handwheel allows for precise control and ease of use. These valves are ideal for applications requiring robust and reliable gate valve solutions.

Wedge Gate Valves are meticulously designed and manufactured to ensure a leakage rate of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). Extensive baseline laboratory testing, including both static and cycle testing, has been conducted to establish the critical design parameters necessary for achieving low-emission sealing in the stem packing seal area and the bonnet gasket sealing area. An in-house testing procedure has been developed and is periodically performed to ensure that our standard product design and manufacturing criteria consistently result in a maximum of 100 ppm VOC leakage prior to shipment.
