the electric directional control valve, 4-way, 3-position direction control of flows.
typical usage includes the transmission device of the hydraulic system.
with the valve version and de-energized solenoid, port 2 (a), port 4 (b), port 1 (t) and port 3(p) are closed.
when the valve version energized coil a, the oil can be from port 3 (p) to port 4 (b), port 2 (a) to port 1 (t).
when the valve version energized coil b, the oil can be from port 3 (p) to port 2 (a), port 4 (b) to port 1 (t).
rated flow :
max. pressure :

working temperature :
min. -20鈩?, max. 90鈩?, with standard bunan gaskets
min. -20鈩?, max. 120鈩?, with optional viton gaskets on request
best use mineral oil with viscosity ranging between 10 and 200 cst
25 micron or better
see cavity data 10-04
before screwing the cartridge on the valve body, ascertain to provide suitable gasket lubrication with clean oil and also be sure to screw the cartridge manually in to reach against the gaskets in the valve body.
