Wedge Gate Valves are engineered to limit volatile organic compound (VOC) leakage to less than 100 parts per million (ppm). Comprehensive baseline laboratory testing, including both static and cycle testing, has been conducted to define the critical design parameters required for achieving low-emission sealing in both the stem packing and bonnet gasket areas. To maintain this standard, KOSEN has developed an in-house testing procedure that is regularly performed, ensuring that every valve meets the VOC leakage limit of 100 ppm before shipment.
