Cast Steel Globe Valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). Extensive baseline laboratory testing, including static and cycle testing, has been conducted to establish the critical design parameters required for achieving low-emission sealing in the stem packing seal area and the bonnet gasket sealing area. An in-house testing procedure has been developed and is periodically performed to ensure that the standard product design and manufacturing criteria consistently result in Cast Steel Globe Valves meeting the maximum 100 ppm VOC leakage limit prior to shipment.
