Description
Technical data
3/2-way solenoid valves are suitable to supply lubricant in different
lubrication circuits and also are used as release valves. Each lubrica- Function principle 3/2-way solenoid valve

switching on separately. Thereby, the pressure inlet is connected Operating temperature –20 to +60 °C
either to one or to the other circuit. Solenoid valves are equipped –4 to +140 °F
Operating pressure 0–400 bar;
with a dry magnetic rotor and a conical seat valve. In their initial 0–5 800 psi
state, the valves always are open to the return line and are activated Flow rate max. 2 400 cm 3 /min
by a return spring. The current switching positions remain as long as max. 146.5 in3/min
current is switched on. Solenoid valves are switchable and resistant Supply voltage 24 V DC, 110 V AC, 50 Hz
230 V AC, 50-60 Hz
to compression in both flow directions. Current draw 0,83 A; 0,2 A; 0,1 A
Rated power 20 W
Pressure connection G 3 /8
