Cast Steel Gate Valves are engineered and manufactured to limit leakage to less than 100 ppm (parts per million) of volatile organic compounds (VOCs). Extensive baseline laboratory testing, including both static and cycle tests, has been conducted to define the critical design parameters required for low-emission sealing at the stem packing and bonnet gasket areas. A dedicated in-house testing procedure is routinely applied to ensure that the standard design and manufacturing processes consistently deliver Cast Steel Gate Valves that meet the strict 100 ppm VOC leakage threshold before shipment.
