PNEUMATIC VALVES

The Fluid Systems Division designs and manufactures a wide range of pneumatic controls designed to operate in the extreme environments of aerospace and derivative applications.

 

Our products combine reliable, proven designs with the latest position indication technologies to deliver cost-effective high levels of performance. Our pneumatic systems and valves are available with a variety of actuators that employ advanced designs and materials--including the first application of composite bleed air valves on an aircraft engine. We also provide a wide range of robust, pneumatically actuated poppet and butterfly shut-off and pressure reducing valves.

 

Pneumatic actuation is accomplished by either using electrical solenoid valves controlling upstream duct pressure or external pressure sources. If ambient temperatures and vibration are too extreme for solenoid operation, solenoids can be remotely located. Our valves are often supplied with electrical position indication, visual position indication, manual override control and other specific customer requirements. Our pedigree includes valves that perform reliably at temperatures above 1150° F (620º C).

 

Market Applications

  • Commercial transports
  • Business and regional jets
  • Helicopters
  • Tiltrotor aircraft
  • Unmanned aerial vehicles
  • Commercial and military aircraft engines
