Cast Steel Gate Valves are precision-engineered to deliver reliable shut-off performance while minimizing environmental emissions. Designed to meet stringent leakage standards, each valve ensures volatile organic compound (VOC) leakage of less than 100 ppm. Extensive baseline testing, including both static and cycle evaluations, has defined critical design parameters at the stem packing and bonnet gasket sealing areas. In-house quality control procedures are routinely conducted to verify compliance, ensuring each valve meets emission and performance targets prior to shipment.
