The DIN 3352 Wedge Gate Valve Factory specializes in manufacturing high-quality wedge gate valves with a flexible wedge design. These valves are constructed from EN 1.0619 carbon steel, providing robustness and durability. They have a large DN400 (16-inch) size and a PN16 pressure rating, equivalent to Pressure Class 150 LB. The valves feature raised face (RF) flanged ends for secure and reliable connections, and a bare stem for easy maintenance and inspection.

Wedge Gate Valves are designed and manufactured to ensure volatile organic compound (VOC) leakage is less than 100 ppm (parts per million). Extensive baseline laboratory testing, including static and cycle tests, has been conducted to establish critical design parameters for achieving low-emission sealing in both the stem packing and bonnet gasket areas. Additionally, an in-house testing procedure is regularly performed to verify that the Wedge Gate Valve consistently meets the maximum 100 ppm VOC leakage standard before shipment.
