Proportional Directional Valve 4WRZE32W9-520-7X/6EG24N9K31/A1D3V - Bosch Rexroth R900975768

When main pressure drops during the cycle the pilot stage should not notice. This size 32 4WRZE therefore takes its pilot oil from an external source and, independently of the main circuit, meters 520 l/min nominal and up to 1600 l/min at operating pressures to 350 bar.

Benefits

• External pilot oil supply and return keep pilot pressure independent of load pressure in the main circuit.
• 520 l/min nominal flow and up to 1600 l/min maximum flow.
• 350 bar operating pressure with FKM seals for HL hydraulic fluid.
• ±10 V voltage command into the on-board electronics, 24 VDC supply.
• Concealed manual override and an integrated pressure reducing valve in the pilot stage.

Applications

It makes sense in systems with strongly varying load pressure such as forging presses, plastics machinery and cyclic test rigs. A dedicated pilot circuit with sufficient supply is a prerequisite. The valve weighs 44 kg and mounts on an ISO 4401-10-09-0-05 subplate.
