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).
