Catalogue excerpts

This type of valve is used on many APUs and engines. APUs can use multiple valves ganged together, for engine starting, running, and purging the fuel manifolds. These valves can also be used as firewall shutoff, deicing, and pilot valves for larger valves on commercial or military aircraft. This Valcor valve is a two way, (normally closed or normally open), solenoid-operated shut-off valve used to control the flow of aviation fuels, non-corrosive gases, or non-aeromatic hydraulic fluids. The flow through the valve is controlled by the action of the plunger and the coil assembly. Energizing the coil causes an electromagnetic field which pulls the plunger and operates the valve. The magnetic force overcomes the mechanical force of the spring in the plunger and lifts the plunger from the coil stop. The seal disc is lifted out of the path of flow. Deenergizing the coil releases the magnetic force holding the plunger and the mechanical force of the spring pushes the plunger and seal disc back to its de-energized position. • Available in Normally Open and Normally Closed • Temperature: -65°F to +250°F • Operating Pressure: 0-1200 PSIG • Proof Pressure: 1500 PSIG Max • Burst Pressure: 3000 PSIG Max • Flow: ESEO between 0.0850.185, Cd=0.65 • Low Current: 0.68 amps max. @ 30 vdc @ 72°F (30 Ohms) • 1.07 amps max @ 30 vdc @ 72°F (47 Ohms) • Lightweight: 0.34 lbs approx. • Low internal leakage: Liquid — 0.5 cc/hr max.
