Water Cooled Three-Way Purge Valve delivers fuel or purge air to the combustion chamber atomizers of a gas-turbine engine. This valve can upgrade existing three-way purge valves to water cooled during refurbishment Unlike the standard water cooled version this Water Cooled Three-Way Purge Valve provides gas turbine owners operational capability and reliability to 95% or better and benefit from maintenance intervals that coincide with hot gas path inspections. With water cooling the gas turbine engine, the owner seeking reliability improvement can now enjoy the same benefits as a turbine owner whose machine is equipped with standard liquid fuel check valves and upgrades to Water-Cooled Liquid Fuel Check Valves.
