Pressure Seal Gate Valves Class 2500 are specially developed for extreme pressure and temperature applications where conventional bolted bonnet valves may not provide the required sealing performance. The pressure seal bonnet design utilizes internal line pressure to increase the sealing force between the bonnet and gasket, ensuring superior leak-tight operation under severe service conditions. Featuring a full-port design, flexible wedge gate, and heavy-duty construction, these valves provide reliable shut-off, low pressure drop, and extended service life. They are ideally suited for power generation plants, high-pressure steam lines, refineries, petrochemical facilities, and critical industrial process systems.
