Cast Steel Globe Valves are engineered for optimal performance, ensuring leakage of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). Through extensive baseline laboratory testing, including static and cycle tests, critical design parameters have been established to achieve low-emission sealing in both the stem packing seal area and the bonnet gasket sealing area. An in-house testing procedure is regularly conducted to ensure that KOSEN Cast Steel Globe Valves consistently meet the stringent 100 ppm VOC leakage standard prior to shipment. This commitment to quality guarantees reliable, high-performance operation in various demanding applications.
