What Is an Alloy Steel Pressure Seal Gate Valve?
An Alloy Steel Pressure Seal Gate Valve is an isolation valve that uses a pressure-assisted bonnet sealing arrangement.
As internal pressure increases, the pressure-seal mechanism increases the sealing force between the bonnet sealing components. This design is particularly useful for demanding high-pressure and high-temperature services.
The gate moves vertically to open or close the pipeline.
When fully open, the gate is removed from the primary flow passage, providing relatively low flow resistance.
