Proportional Directional Valve 4WRZE25E220-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954670

Symbol E at 220 l/min produces a combination for axes that must hold position accurately without being oversized. The 4WRZE25E220-7X/6EG24ETK31/A1D3M is piloted internally and controls up to an operating pressure of 350 bar.

Benefits

• Nominal flow 220 l/min, matched to medium cylinder areas in size 25.
• Spool symbol E, centre position closed according to the associated switching symbol.
• Internal pilot oil supply and internal return without a separate control circuit.
• Operating pressure up to 350 bar, up to 870 l/min possible through the valve.
• On-board electronics, analog ±10 V command value, 24 VDC supply.
• 7-pole connector (6 + PE) to EN 175201-804, mass 20.52 kg.

Applications

The variant suits test rigs and presses whose axes travel short distances precisely. Limiting nominal flow to 220 l/min improves resolution in the lower command range. Internal piloting requires permanent pressure in the main circuit.
