This solenoid-operated 3-way, 2-position cartridge is a direct-acting, poppet-style directional valve. The valve is
normally open between port 1 and port 2 with port 3 blocked. Energizing the valve connects port 2 to 3 and blocks
port 1. All flow paths are bidirectional and blocked paths are blocked in both directions. Due to the poppet style
construction, this valve has extremely low leakage.
This valve is designed to be used with 740 and 747 Series coils.
