Directional Spool Valve 4WEH16E7X/6EG24N9K4QM0G24/P4,5 - Bosch Rexroth R901421187

The 4WEH16E7X/6EG24N9K4QM0G24/P4,5 directional spool valve draws its pilot oil externally and drains it externally. In size 16 it switches up to 300 l/min at a maximum operating pressure of 280 bar following spool symbol E.

Benefits

• External pilot oil supply and external pilot oil return, independent of the working circuit
• Flow up to 300 l/min at operating pressure up to 280 bar
• Spool symbol E, three switching positions, four ports
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• ISO 4401-07-07-0-05 hole pattern in size 16, weight 10.54 kg

Application

The version suits circuits where system pressure can drop below the minimum pilot pressure, for example in accumulator or idle-circulation operation. A separate pilot pressure source then keeps the valve able to switch. Mounting is by a subplate to ISO 4401-07-07-0-05.

Manufacturer

Bosch Rexroth lists this valve under material number R901421187. The manufacturer datasheet states the required pilot pressure.
