Proportional Directional Valve 4WRTE25V220L-4X/6EG24ETK31/A1M - Bosch Rexroth R900957471

A valve that routes its pilot circuit internally saves two fittings and two lines during assembly. The 4WRTE25V220L-4X/6EG24ETK31/A1M uses that layout and meters 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Internal pilot oil supply and internal return, the manifold needs no X and Y line.
• 220 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
• Internal spool position feedback for repeatable metering areas.
• Plus/minus 10 V command value, on-board electronics, 24 VDC supply voltage.
• Spool symbol V with a linear characteristic, three switching positions on four ports.
• 17.94 kg, NBR seals, ISO 4401-08-08-0-05 interface, 7-pole connector (6 + PE).

Application

The valve suits closed loop cylinder axes in presses, testing machines and machine tools. Its linear characteristic makes tuning the superimposed position controller easier. Plants with an external pilot pressure supply should use the matching variant.
