Cast Steel Gate Valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds (VOC). Extensive baseline laboratory testing, including both static and cycle testing, has been conducted to establish the critical design parameters necessary for low-emission sealing. These tests focus on the stem packing seal area and the bonnet gasket sealing area. In-house testing procedures are periodically performed to ensure that the standard product design and manufacturing criteria consistently result in the KOSEN Cast Steel Gate Valve meeting a maximum of 100 ppm VOC leakage prior to shipment.
