Cavitating Pintle Valve

JASC's Cavitating Pintle Valve

JASC’s Cavitating Pintle Valve is a high-speed motor driven pintle valve with electronic control for metering of high-pressure gaseous hydrogen or silane. These valves form the heart of NASA’s Hyper-X Hypersonic Experimental Research Vehicle Fuel System. Pintle Valves, considered the key elements of the vehicle’s propulsion system, are designed for accurate metering of gaseous hydrogen (fuel) and a mixture of gaseous hydrogen and silane (a pyrophoric igniter) to the engine’s combustor for the duration of the flight. JASC’s Pintle Valves have accurate fuel metering, excellent pressure recovery throughout the operating range and meets or exceeds the environmental requirement of HX-279 for shock, vibration, and acceleration.
