What Is a Pressure Seal Gate Valve?
A pressure seal gate valve is designed for high-pressure and high-temperature industrial applications where conventional bolted bonnet valves may not provide sufficient sealing reliability.
The pressure seal bonnet structure utilizes internal pressure to improve sealing performance, making these valves ideal for demanding power generation and steam service environments.
