Pressure Seal valves are used primarily, but not limited, to power generation plants with fossil, coal, thermal, gas, nuclear power plants, steam power stations, etc.
Pressure seal valves are excellent in the following conditions: high pressure, high temperature, steam, oxidizing environments, among others. One of the most important features of MICRONE Pressure Seal Cast Steel Valves is it ability to use the pressure line to assist in the seal of the valve with a preloaded metallic or graphite pressure seal gasket placed between body and bonnet which reduces weight for easy installation and maintenance increasing safety and seal of the body-bonnet joint.
Pressure Seal Valves are designed in accordance ASME B16.34. Pressure Classes 600, 900, 1500 & 2500 # and sizes from 2” up to 24” nominal diameter.
