JASC Three-Way Purge Valve Description
The three way purge valve offers a means to deliver fuel or purge air to the combustion chamber atomizers of a gas turbine engine. The valve operates at high pressure and temperature while maintaining essentially zero leakage between individual air and fuel sources. The inherent scraping action of the dynamic seals provide long life operation with contaminated fluids. Fuel recirculation for this unit is optional.
