Large cylinders fill only as fast as the valve lets oil through. The 4WRZE32E1-520-7X is therefore rated at 520 l/min nominal flow, up to 1600 l/min maximum flow and 350 bar operating pressure.
Benefits
- 520 l/min nominal flow with up to 1600 l/min peak flow in size 32.
- 4 to 20 mA command value through the on-board electronics, resistant to interference on long signal runs.
- Internal pilot oil supply and internal return, so no extra pilot lines are needed on the manifold.
- 350 bar operating pressure with NBR seals, connection diagram ISO 4401-10-09-0-05.
- 43.92 kg weight, three switching positions, four ports, version without a pressure reducing valve in the pilot circuit.
