Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901208584

Selecting a valve for a large cylinder axis starts at nominal flow paired with the command interface: this size 32 unit converts ±10 V into 360 l/min at operating pressures up to 350 bar.

Key benefits

• 360 l/min nominal flow inside a body rated for 1600 l/min maximum flow, which leaves headroom for rapid traverse phases.
• ±10 V command value wired straight to a controller analog output, no signal converter required.
• External pilot oil supply plus external pilot oil return keep the pilot circuit clear of the main circuit, useful where the tank line carries back pressure.
• Integrated pressure reducing valve holds pilot pressure steady across the whole working range to 350 bar.
• 44.26 kg on an ISO 4401-10-09-0-05 interface, so the subplate has to be sized accordingly.

Technical data

Applications

Presses, forging lines and large test rigs are the usual home for this class, wherever one cylinder has to be controlled at high flow. The external pilot supply suits machines that already run a dedicated pilot pressure circuit. Hydraulic fluid is HL, seals are made of NBR.
