Wedge Gate Valves are engineered to limit the leakage of volatile organic compounds (VOCs) to less than 100 parts per million (ppm). Comprehensive baseline laboratory tests, including static and cycle testing, have been conducted to identify the critical design parameters required for achieving low-emission sealing in both the stem packing and bonnet gasket areas. Additionally, an in-house testing procedure has been established and is regularly executed to ensure that the standard design and manufacturing processes consistently result in a maximum VOC leakage of 100 ppm for Wedge Gate Valves before they are shipped.
