The Wedge Gate Valves are meticulously engineered and produced to achieve 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 identify the critical design parameters required for effective low-emission sealing in both the stem packing seal area and the bonnet gasket sealing area. Additionally, an in-house testing procedure has been established and is regularly executed to ensure that the standard product design and manufacturing processes consistently result in a maximum VOC leakage of 100 ppm before the valves are shipped.
