Our Cast Steel Gate Valves are engineered to achieve a VOC leakage of less than 100 ppm (parts per million). Extensive baseline laboratory tests, including both static and cycle testing, have been conducted to establish the critical design parameters needed for effective low-emission sealing in the stem packing and bonnet gasket areas. A dedicated in-house testing procedure is regularly performed to verify that the valve's design and manufacturing standards consistently ensure that each KOSEN Cast Steel Gate Valve meets the 100 ppm VOC leakage limit before shipment.
