Parker Aerospace anti-draindown valves prevent the draining of lubricating oil from the tank or reservoir through lubrication system components (like pumps) into the gearbox.
Parker Aerospace anti-ice pressure regulating shut-off valve controls the application of HP3 air to the downstream anti-ice pressure relief valve to maintain the engine intake (nacelle) free from ice under fault-free operation.
The auxiliary power unit (APU) feed shutoff valve is a ball valve operated by a 28 VDC motor actuator. The valve is installed in the APU feed fuel line to prevent fuel from flowing into the APU compartment during an APU shutdown.
Proven lifesavers, Stratoflex’s breakaway valves separate under high loads on fluid lines exceeding a predetermined value. Upon separation, the valves automatically seal the fluids in the lines to effectively prevent spills.
The climb and dive valve controls tank-to-ambient and ambient-to-tank pressure differentials during ground and flight operations. When an aircraft climbs, ambient air pressure decreases; during aircraft descent, ambient pressure increases.
Parker's dual flow shutoff valve (DFSOV) is used on the inert gas generation system of an aircraft to control the nitrogen enriched air (NEA) flow to the fuel tanks.
Engine feed shutoff valves are ball valves operated by 28 vdc motor actuators. Each valve is installed in an engine feed fuel line to prevent fuel from flowing into wing fire zones during an engine shutdown.
Parker Aerospace filter bypass valve provides emergency flow of lubricating oil to turbine engines when the filter is clogged or missing.
The wing tank is divided into a number of semi-sealed compartments that allow easy fuel migration inboard while minimizing fuel migration outboard. The compartments contain check valves that are the boundaries between compartments.
Parker Aerospace fuel manifolds provide fuel distribution to multiple injectors (nozzles) on gas turbine engines and can offer single or multiple circuits for staged flows.
The fuel swing check valve is an inline, swing flapper check valve that has many uses; one of which is to prevent reverse fuel flow from the ejector pumps to the engine feed subsystem.
Handling bleed valves (HBVs) control the outlet of bleed air from the engine and into other aircraft systems. They are primarily used for engine starting, transient bleed, and surge control.
