We offer a complete product range of MOTOR-OPERATED FUEL SHUTOFF VALVE, Aerospace Electrohydraulic Servo valve and BREAKAWAY VALVE
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.
These valves are a series of three- or four-way electrohydraulic servovalves (EHSVs) commonly used to control position, velocity, and force in a variety of hydraulic system, fuel system, and engine control applications. Driving aerospace hydraulic actuators or motors in closed-loop servosystems, the EHSVs provide flows to 10 GPM at 1000 psi drop across the valve. The first stage is driven by an efficient force motor that is balanced so that lateral accelerations have little effect on output flow. The electrohydraulic servovalves provide unparalleled performance due to the highly reliable jet-pipe first-stage and large second-stage spool design. The result is an exceptionally contamination-resistant, erosion-tolerant, and high-flow servovalve that's designed to last. With an ability to perform in a contaminated environment, the Parker EHSV allows particles as large as 208 microns (0.008") to pass through the first stage without difficulty. Because the first-stage fluid impinges on a receiver that is fixed to the second stage, the Jet-Pipe® motor has low first-stage noise. The integrity of the projector jet stream results in optimum hydraulic efficiency (first-stage pressureflow recovery) and better dynamic performance at low fluid temperatures.
Proven lifesavers, Stratoflex 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. Breakaway valves are typically used on fuel lines, main fuel tanks, extended range aircraft auxiliary fuel tanks, air-to-air refueling systems, and fall-away external tanks. Tank vent lines often use the single valve versions. The basic design incorporates a butterfly valve mounted to a cam shaft loaded by a coil spring. This design allows for a small envelope, lightweight, and minimum pressure drop across the coupling. The mechanism consists of two valve plates andor a single plate and detent post. These are held against each other by spring action until the fuse section separates to allow valve closure. An internal sealing sleeve is installed in between the interface joint of the two valve bodies and seals the fluid leakage from internal to external before valve bodies are totally separated. This construction permits a clean valve passage, minimizing ice formation and contamination. No parts are released to interfere with the valve operation during closure.
