DIN 3352 F7 Gate Valve, EN 1.0619, DN100, PN40, BB, OS&Y, RF

Our China DIN 3352 F7 Gate Valve Plant offers high-quality wedge gate valves designed for reliable on-off control. These valves feature a carbon steel body made from EN 1.0619 material, ensuring durability and strength. With a diameter of DN100 (4 inches) and a pressure rating of PN40 (Class 300 LB), the bolted bonnet design provides easy maintenance and inspection. The outside screw and yoke (OS&Y) mechanism ensures smooth operation and precise control. The raised face (RF) flanged ends facilitate secure and leak-free connections.

The 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 tests, 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 the standard product design and manufacturing criteria consistently result in the Wedge Gate Valve meeting a maximum of 100 ppm VOC leakage prior to shipment.
