Pressure Seal Construction (Fig. 2)is used for high pressure service. The feature about the pressure seal bonnet :
The higher the internal pressure, the better the sealing force.
Pressure Seal Construction is suitable for 170 bar and above
Pressure Seal Valve proven their capability to handle increasingly demanding forsil and steam isolation application
Bolted Bonnet Valve(Fig. 1)
The body flange and bonnet flange are connected with studs and nuts with a gasket.The system pressure increased, the potential for leakage also increased.
One of the important components in Pressure Seal Valve is pressure seal gasket.
