Rotary Select Valves Isolating Hydraulic Pressure

Canyon Engineering Products has developed a line of manual rotary select valves which enable aircraft operators to isolate hydraulic pressure from other specific systems, to permit ground maintenance of aircraft.


The manual rotary select valves come with dual or multiple ports, and are qualified for aerospace hydraulic systems up to 5,000 psi.


Canyon Engineering Products’ Rudder Isolation Valve has operating pressures of 5,076 psig, with a 7.92 gpm flow rate at 7.25 psid max. The lightweight housing is made of titanium and results in overall unit dry weight of 1,050 lb. When in use, the valve isolates the rudder actuator from the main hydraulic system during aircraft ground maintenance, thereby preventing movement of the aircraft rudder.
