Water Cooled Liquid Fuel Check Valve

JASC has manufactured and shipped more than 10,000 Water-Cooled Liquid Fuel Check Valves for dual-fuel gas turbine engines used in power generation applications. This state-of-the-art Water-Cooled Liquid Fuel Check Valve is a modified version of JASC’s proven Liquid Fuel Check Valve design and incorporates active internal cooling without requiring any changes to existing fuel lines.
JASC’s Water-Cooled Liquid Fuel Check Valves maintain a Class 6 seal in both the check and reverse-flow directions, effectively preventing reverse flow from the hot gas path to the hot gas path. The integrated water-cooling system maintains internal valve temperatures below the diesel fuel coking threshold (approximately 250 °F), even when operating in ambient environments exceeding 500 °F.
Laboratory testing has demonstrated successful operation with cooling water temperatures up to 150 °F, water pressure of 40 psig, and flow rates as low as 0.25 GPM, while consistently maintaining internal check valve temperatures below the coking threshold.
