Parker Aerospace 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.... 

Highly engineered valve installed within fluid conveyance systems to prevent the loss of reservoir fluid in the event of loss of system pressure.... 

派克航空航天自動排氣閥在閉式液壓系統中自動檢測和排出空氣，無需維護人員的介入。設備可以通過飛機的計算系統直接控制。 ... 

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.... 

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.... 

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.... 

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.... 

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.... 

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.... 

Parker 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....
