On a new build the number of pipe runs decides the build time. This valve needs no pilot line, because pilot supply and pilot return run internally, and still provides 520 l/min nominal flow with spool symbol E at up to 350 bar.

Total price
When a valve station is built from scratch, every additional pipe run costs time and material. The 4WRZ32E520-7X/6EG24N9ETK4/V feeds and drains pilot oil internally, so assembly is limited to the four working ports, at 520 l/min nominal flow.
Key benefits
- Internal pilot oil supply and internal return, no additional piping at the manifold.
- 520 l/min nominal flow in size 32, maximum flow 1600 l/min.
- Spool symbol E with 3 switching positions and 4 ports, connection pattern ISO 4401-10-09-0-05.
- Operating pressure up to 350 bar, FKM seals, HL hydraulic fluid.
- Concealed manual override, version without pilot pressure reducing valve.
- 43.16 kg weight, external electronics, 24 VDC, 3-pole connector (2 + PE).

Applications
Intended for newly built power units in which the valve station is to stay compact. Doing without external pilot lines shortens commissioning and later fault finding. At 520 l/min nominal flow the valve suits main axes on presses, shears and hoists.
