Pressure seal gate valves are used for high pressure service, typically for pressures above 100 bar. The unique feature of the pressure seal bonnet is that the body-bonnet joints seal improves as the internal pressure within the valve increases.
The main applications are: petrochemical industry, steam circuits, boiler circulation, oil and gas applications, power stations
Common used types of medium encountered are: steam, condensate, boiler feedwater
Typical pressure rating of the valve is 900, 1,500 and 2,500 pounds.
