the electric directional control valve, 4-way, 2-position direction control of flows.

typical usage includes the transmission device of the hydraulic system.

with the valve version and de-energized solenoid, the oil flow can be from port 3 (p) to port 2 (a), port 4 (b) to port 1 (t).

when the valve version energized, the oil flow can be from port 3 (p) to port 4 (b), port 2(a) to port 1(t).
