Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9ETK31/A1M - Bosch Rexroth R900975771

If the control signal fails, a heavy axis still has to reach a safe position. The 4WRZE32W6-520-7X/6EG24N9ETK31/A1M carries a concealed auxiliary actuation for that case and meters 520 l/min at 350 bar from a ±10 V command in normal service.

Benefits

• Concealed auxiliary actuation for fault cases, protected against accidental adjustment while running.
• 520 l/min nominal flow at 350 bar, the size 32 body permits up to 1600 l/min.
• Internal pilot oil supply and internal return keep piping simple.
• ±10 V command with on-board electronics on 24 V DC through a 7-pole connector (6 + PE).
• 43.6 kg, W6 spool, NBR seals, HL hydraulic fluid.

Applications

The valve controls lifting, feed and clamping axes in presses, steel plants and large handling equipment. Internal pilot routing keeps assembly work low. With the ISO 4401-10-09-0-05 interface it fits subplates already installed in size 32.
