Special Features:

Pneumatically actuated; servo pressure is modulated by the flow control sensor; air pressure is directed to thesmall actuator piston to provide the valve opening force. A valve-open position switch is provided as part of thebuilt in test system. The valve operates in conjunction with the flow control sensor to regulate engine bleed air flow to the airconditioning pack; schedule air flow to control avionics cooling capacity

Properties:

A valve having two or more ports with valve stem or pilot needle in a normally open or closed position. It is specifically designed to stop or start or change the flow of fluid by means of the magnetic action of an electric coil on a moveable core or plunger. The valve may be equipped with a manual opening or closing device. For items with three or more ports that utilize a reciprocating slide with recess areas which mate with ports in an integral or replaceable ported sleeve, see valve (1), linear, directional control. It may be inline or cartridge (manifold) design. Excludes valve (1), butterfly.
