Cast Steel Gate Valves are engineered to ensure minimal leakage, with a strict limit of less than 100 ppm (parts per million) of volatile organic compounds (VOCs). These valves undergo extensive baseline laboratory testing, including static and cycle tests, to establish the necessary design parameters for achieving low-emission sealing in both the stem packing seal and bonnet gasket areas. A comprehensive in-house testing procedure is regularly performed to ensure that the standard product design and manufacturing criteria consistently meet the required VOC leakage standards before shipment.
