to give on-off control of flows of 20 litres/min (5.3 us gpm) and pressure up to 350 bar (5000 psi). 

typical usage includes the control of actuators in a hydraulic system.

with the valve version and de-energised solenoid, the oil flow is stopped from port 2 to port 1 and is free from port 1 to port 2. 

when the solenoid is energized, the flow is free from port 2 to port 1 but port 1 to port 2 restricted.

rated flow :
20 l/min 

max. pressure :
350 bar

oil leaks from port 2 to port 1 :
0.30 ml/min (5 dpm) at 210 bar and oil viscosity of 46 cst

working temperature : 
min. -20鈩?, max. 90鈩?, with standard bunan gaskets
min. -20鈩?, max. 120鈩?, with optional viton gaskets on request

fluid :
best use mineral oil with viscosity ranging between 10 and 200 cst

filter :
25 micron or better

cavities :
see cavity data 08-02

installation :
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.
