Circor Aerospace

Hydraulic solenoid valves and manifolded sub-systems are used on primary and secondary flight control systems, landing gear deployment, door detection, braking systems and other pressure and flow controls sub-systems. Industria fuel valves are employed throughout the fuel delivery and control system for main propulsion turbine engines and auxiliary power turbine systems. Complete rescue power systems, including solenoid valves, accumulators, pressure indicators and fill valves are provided for helicopter and drone landing gear applications. Pressure switches are used on numerous platforms, including aircrafts, helicopters, radars and submarines, and are designed to resist the most hostile vibration and temperature environments and pressures up to 525 bar (7600 psig). 1e Hydraulic Fuel Valves By utilizing proven state-of-the-art designs, CIRCOR Aerospace's Motor-operated Valves meet or exceed the demanding requirements of today's high-performance turbine powered aircraft. The product line includes a full size range of gate valves and a full size range of ball valves, plug, spool, and butterfly valves. The electric motor actuator is designed and manufacturered using well-established methodology to provide a reliable, long cycle life, no maintenance acutator for electrical operation of valve mechanisms. These valves are qualified in accordance with the requirements of MIL-STD-810C and have been test proven to handle 10,000 cycles minimum at a torque of 45 lb/inch (capabilities to 50,000 cycles and greater). Units have been designed and tested in accordance with MIL-V-8608 an MIL-M-8609. Emission of radio frequency interference has also been controlled. The units have been qualified and can be manufactured to meet the requirements of RTCA document DO-160A, Category A (equivalent to Boeing document D6-16050-2, Category 3A).
