Three-Way Purge Valve offers a means to delivery fuel or purge air to the combustion chamber atomizers of a gas-turbine. The three-way purge 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 provides long-life operation with contaminated fluids. Fuel recirculation for this unit is optional. This unit can be refurbished or upgraded to the new water-cooled three-way purge valve.
