A subplate drilled with only four holes leaves no room for pilot lines. The 4WRZ25E220-7X/6EG24N9ETK4/V still fits it, because pilot oil is taken internally and returned internally, and it meters 220 l/min nominal flow.

Total price
Older subplates often provide only P, T, A and B, without bores for X and Y. The 4WRZ25E220-7X/6EG24N9ETK4/V manages with that, routes its pilot oil internally and meters 220 l/min nominal flow in size 25.
Benefits
- Pilot oil supplied and returned internally, four ports on the plate are enough.
- 220 l/min nominal flow within a maximum flow of 870 l/min.
- Spool symbol E, 3 switching positions, ISO 4401-08-08-0-05 interface, 350 bar operating pressure.
- 19.96 kg weight, FKM seals, rated for HL hydraulic fluid.
- No internal pressure reducing valve, with concealed auxiliary actuation for setup work.

Applications
Replacement pays off on existing machines whose manifold should not be re-drilled. Since the pilot stage feeds from the main channel, system pressure has to stay inside the permitted range of the series. The amplifier card remains in the cabinet and connects through the 7-pole plug.
