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.
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.
A series of three- or four-way electrohydraulic servovalves (EHSVs) that drive actuators or motors in closed-loop servosystems used to control position, velocity, and force in hydraulic systems, fuel systems, and engine control applications.
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.
Parker's park brake valves are designed for long, reliable service life while holding the aircraft stationary in the closed (locked) position. Valve models range from fairly simple devices to more complex models with additional features.
Parker’s reservoir type master cylinders are designed for long, reliable service life and feature a reservoir integrated into the housing. This eliminates the need for a separate, remotely mounted reservoir.
The Parker Aerospace automatic bleed valve provides automatic detection and bleeding of air in a closed-hydraulic system without input from maintenance personnel. The device may be controlled directly through the aircraft's computing system.
Parker’s push-type master cylinders utilize hardened steel rods, aluminum housings, and pistons that have low seal friction, which means they are designed for long, reliable service life.
Master cylinders are located in the cockpit on each of the pilot’s rudder pedals, using pressure to actuate the brakes on an aircraft. Parker’s pull-type master cylinders have been designed for long, reliable service life.
The shimmy damper is a hydraulic fluid-filled cylinder that prevents rapid movement of the nose or main landing gear without interfering with slower operations.
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.
Incorporates a number of solenoid valves (two to six) that are used to control pneumatic valves. The solenoid bank is designed to be located in zone two of the engine. The solenoid valves are connected, via servo pipes, to individual pneumatic valves.
Parker Aerospace's shutoff valve/volume compensator is a multi-function hydraulic valve. Its main purpose is to increase aircraft efficiency and provide pedal feedback to the pilot.
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.
The motor-operated fuel shutoff valve is spar-mounted and is driven by a 28 VDC brush-type motor actuator to open and close when electrically commanded.
When the aircraft is connected to a ground refueling source, the fuel management system commands the refuel shutoff valve to close when the selected fuel quantity is reached in conjunction with the refuel control solenoid or pilot-operated float valve.
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.
Highly engineered valve installed within fluid conveyance systems to prevent the loss of reservoir fluid in the event of loss of system pressure.
