Proportional Directional Valve 4WRZ25E325-7X/6EG24N9EK4/V - Bosch Rexroth R900955196

If the manifold lacks a pilot pressure port, the valve has to branch its own pilot oil. The 4WRZ25E325-7X/6EG24N9EK4/V does so internally and returns pilot oil through a dedicated outlet, at a weight of 19.86 kg.

Benefits

• Pilot oil taken internally, drained externally, no pilot pressure port needed on the manifold.
• 325 l/min nominal flow within a maximum flow of 870 l/min.
• 19.86 kg weight, FKM seals, spool symbol E with 3 switching positions.
• 350 bar maximum operating pressure, subplate mounting ISO 4401-08-08-0-05 in size 25.
• No internal pressure reducing valve, with concealed auxiliary actuation for setup work.

Applications

The version is used when retrofitting existing manifolds where only the drain path is free. Pilot pressure comes from the main channel, so system pressure has to stay inside the permitted range. The amplifier card sits in the cabinet and connects through the 7-pole plug.
