Pressure Seal Gate Valve -- Flexible Wedge WC9 High Pressure
Engineered pressure seal gate valves in WC9 Cr-Mo steel with flexible wedge design for main steam and hot reheat isolation in thermal power and high-pressure process plants. The pressure seal bonnet tightens under line pressure, eliminating large diameter body-bonnet bolting at elevated temperatures. Full port design ensures minimal pressure drop and pigging compatibility.
