Total price
An axis that should be unloaded at standstill needs the right spool symbol and a pilot stage that still works at low working pressure. The 4WRZE25E1-220-7X/6EG24TK31/A1D3M combines symbol E1 with external pilot oil supply at 220 l/min nominal flow.
Benefits
- Spool symbol E1 gives the axis defined behaviour when it is unloaded in centre position.
- External pilot oil supply keeps the valve able to shift even when working pressure is unloaded.
- Internal pilot oil return cuts piping work at the valve manifold.
- 220 l/min nominal flow, up to 870 l/min maximum flow, 350 bar operating pressure.
- Integrated pressure reducing valve plus on-board electronics with spool position feedback.
- UKCA conformity including electromagnetic compatibility to SI2016/1091.
