Proportional Directional Valve 4WRKE32E1-600L-3X/6EG24K31/A1D3M - Bosch Rexroth R901102982

Large press and forging axes call for a flow rate that a direct-operated valve can no longer deliver. This pilot-operated 4/3 proportional directional valve in size 32 converts a ±10 V command value into 600 l/min of nominal flow and allows peaks of 1600 l/min, at a maximum operating pressure of 350 bar.

Benefits

• Nominal flow of 600 l/min with peaks to 1600 l/min, no change of subplate required
• Spool symbol E1 with a linear characteristic curve gives even acceleration ramps
• Operating pressure to 350 bar covers the upper performance range of industrial hydraulics
• Internal spool position feedback plus on-board electronics on 24 VDC replace an external control amplifier
• External pilot oil supply with external pilot oil return keeps the pilot circuit clear of the main circuit
• Connection diagram ISO 4401-10-09-0-05 at 37.2 kg fits any standard NG32 mounting plate

Application

Main cylinder axes on hydraulic presses, forging manipulators and rolling mill adjustments are the typical fit. Wherever 600 l/min has to be metered accurately, the valve replaces a pilot stage plus external controller. The separate pilot circuit also suits installations where main pressure fluctuates strongly.
