Cast Steel Globe Valves are meticulously engineered to limit the leakage of volatile organic compounds (VOCs) to less than 100 parts per million (ppm). Comprehensive baseline laboratory testing, encompassing both static and cycle tests, has been conducted to identify the critical design parameters required for achieving low-emission sealing in the stem packing and bonnet gasket areas. An in-house testing protocol has been established and is regularly executed to ensure that the standard design and manufacturing processes consistently result in our Cast Steel Globe Valves meeting the maximum allowable VOC leakage of 100 ppm before shipment.
