Wedge Gate Valves are engineered to meet stringent environmental standards, designed to ensure leakage of volatile organic compounds (VOCs) remains below 100 ppm (parts per million). Comprehensive laboratory testing, including static and cycle testing, has established critical design parameters to ensure low-emission sealing in both the stem packing and bonnet gasket areas. A robust in-house testing procedure verifies that each valve meets this low-emission benchmark prior to shipment, ensuring consistent quality and performance in the field.
