Cast Steel Gate Valves are meticulously designed and manufactured to ensure minimal leakage of volatile organic compounds (VOCs), with a stringent limit of less than 100 parts per million (ppm). Extensive baseline laboratory testing, encompassing both static and cycle testing, has been conducted to establish critical design parameters. These parameters are essential for achieving low-emission sealing in both the stem packing seal area and the bonnet gasket sealing area. To maintain this high standard, an in-house testing procedure has been developed and is periodically performed. This ensures that the standard product design and manufacturing criteria consistently result in Cast Steel Gate Valves meeting the maximum allowable leakage of 100 ppm VOCs prior to shipment.
