Canyon Engineering Products has also developed and qualified a 3-port, 2 position valve. This valve is used for 3000psi hydraulic systems with 6.08 GPM flow rate at 58 PSID max. The overall weight of this valve is 1.90lb. This valve is also used for aircraft ground maintenance, so that the nose door is isolated from the hydraulic system, for servicing.
Another 3-way, 2-position valve developed and qualified by Canyon Engineering Products is rated for 4000psi hydraulic service. Manually operated, the valve controls hydraulic flow to the accumulator, as it distributes pressure from the aircraft’s hand pump to the accumulator bottles. This valve is manufactured with a lightweight titanium housing, resulting in unit weight of 2.5 lb., with flow rate of 1 GPM at 50 PSID max.
Canyon also developed and qualified a 4-way, 3-position select valve which is used to control hydraulic pressure to multiple hydraulic systems. The valve is used to distribute hydraulic pressure from a hand pump to one of three discrete hydraulic systems. This valve operates at 300 psig and flows at 1.5GPM at 30PSID and weighs 4.0lbs.
