Wedge Gate Valves are meticulously designed and manufactured to achieve ultra-low leakage rates, specifically less than 100 ppm (parts per million) of volatile organic compounds (VOCs). This stringent emission control is a result of extensive baseline laboratory testing, which includes both static and cycle testing. These tests have been instrumental in establishing critical design parameters that ensure low-emission sealing in key areas such as the stem packing seal and the bonnet gasket sealing area. To maintain the highest standards of quality and performance, an in-house testing procedure has been developed. This procedure is periodically executed to verify that the standard product design and manufacturing criteria consistently result in the Wedge Gate Valve meeting the maximum allowable leakage rate of 100 ppm VOCs prior to shipment. This rigorous approach guarantees that each valve is reliable, efficient, and environmentally friendly, making it suitable for a wide range of demanding applications.
