Liquid Fuel Check Valve

The JASC Liquid Fuel Check Valve enhances fuel system reliability in dual-fuel turbine engines. Designed for high-flow, zero-leak performance, the valve operates reliably with a wide range of fluids, including Stoddard solvent, jet fuels, hydraulic oil, synthetic oil, and air.
The valve incorporates fluid dampening to ensure stable operation from initial cracking through full flow. Its inverted spool design utilizes a Helmholtz resonator to dampen fuel pressure imbalances, delivering significantly greater operational stability than traditional ball-and-spring check valves. By metering fuel and maintaining a controlled delta pressure across the valve, the inverted spool enables uniform, simultaneous valve opening.
To meet each customer’s specific performance requirements, every JASC Liquid Fuel Check Valve undergoes rigorous testing. The valves are contamination-tolerant, resistant to chatter, and provide an ANSI Class 6 zero-leak seal in the check direction.
The valve is fully refurbishable, allowing it to be restored to original operating condition indefinitely. This capability significantly reduces the total cost of ownership compared with non-refurbishable liquid-fuel check valves.
