1/4" NPT 5 Port 4 Way 3 Position Solenoid Valve Exhaust Center (24VDC Grommet) 200C Coil
This is a pneumatic directional solenoid valve with a four-way operation & five ports (P = Pressure, A = Outlet, EA = Exhaust for port A). Four-way, three-position valves are generally used to fully extend a double acting (air return) cylinder, or in applications with similar operation. The center position is configured as Exhaust Center - to allow the cylinder to freely move, i.e. be hand-adjusted.
