The Cast Steel Globe Valves are meticulously designed and manufactured to achieve an exceptionally low leakage rate of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). To ensure this level of performance, extensive baseline laboratory testing, including both static and cycle tests, has been conducted. This testing has established the critical design parameters required to achieve low-emission sealing in both the stem packing seal area and the bonnet gasket sealing area. Additionally, an in-house testing procedure has been developed and is regularly executed to confirm that the standard product design and manufacturing criteria consistently result in Cast Steel Globe Valves meeting the maximum VOC leakage limit of 100 ppm prior to shipment.
