RED POINT®
Pressure Seal Bonnet Gate Valves
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.
