to give on-off control of flows of 70 l/min (18.5 us gpm) and pressure up to 280 bar (4000 psi).
typical usage includes the control of actuators in a hydraulic system.
with the valve version and de-energised solenoid, the oil flow is free from port 2 to port 1 but port 1 to port 2 restricted.
when the solenoid is energised, the flow can be from port 1 to port 2, but stopped from port 2 to port 1.
rated flow :
max. pressure :
oil leaks from port 2 to port 1 :
0.30 ml/min (5 dpm) at 210 bar and oil viscosity of 46 cst when the solenoid is energised.
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 12-02
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.
