Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9K31/F1V - Bosch Rexroth R901064066

A voltage command loses accuracy over long cable runs, a current command does not. The 4WRZE32W8-360-7X/6EG24N9K31/F1V is therefore driven by 4 to 20 mA and controls 360 l/min nominal flow in size 32 at 350 bar operating pressure, with external pilot oil supply and external pilot oil return.

Benefits

• 4 to 20 mA command value into the on-board electronics - immune to long line runs, and a broken wire shows up in the signal.
• 360 l/min nominal flow with up to 1600 l/min maximum and 350 bar operating pressure.
• External pilot oil supply and external pilot oil return for systems with their own pilot station.
• Spool symbol W8, three switching positions, four ports, ISO 4401-10-09-0-05 mounting pattern.
• 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804, FKM seals, weight 43.1 kg.

Applications

A good fit for spread-out installations where valve and controller sit tens of metres apart: metallurgical plant, water engineering, large test rigs. The 360 l/min rating serves axes smaller than the 520 l/min variant of the same series while sharing the identical manifold interface.
