Proportional Directional Valve 4WRZE25E220-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901031159

A standard axis at 220 l/min is easiest to build around a valve that asks for neither pilot lines nor a voltage interface. The 4WRZE25E220-7X/6EG24ETK31/F1D3M brings both, works with spool symbol E and withstands operating pressures up to 350 bar.

Benefits

• Internal pilot oil supply and internal return keep the connection down to four lines.
• Spool symbol E with a fine control range, 220 l/min nominal flow and 3 switching positions.
• A 4...20 mA command works with the current outputs of common controllers.
• A built-in pressure reducing valve holds pilot pressure constant despite internal extraction.
• UKCA conformity to SI2016/1091, mounting pattern ISO 4401-08-08-0-05, weight 20.58 kg.

Applications

The valve controls medium feed, infeed and lifting axes in machinery and plant construction. Since pilot feed and return sit inside, piping stays limited to P, T, A and B. NBR seals suit mineral oil of class HL.

Manufacturer

Bosch Rexroth, material number R901031159. In the type code 4WRZE25E220-7X/6EG24ETK31/F1D3M the letter E marks the spool symbol, ET the internal pilot routing and F1 the 4...20 mA current command. The characteristic curves and installation dimensions are given in data sheet RE 29115 and RE 07600-B.
