Proportional Directional Valve 4WRZE25E220-7X/6EG24N9TK31/A1M - Bosch Rexroth R901313532

When pilot pressure arrives from its own circuit while the pilot oil may return internally, one line can be dropped. The 4WRZE25E220-7X/6EG24N9TK31/A1M is laid out that way and meters 220 l/min nominal flow at an operating pressure of up to 350 bar.

Benefits

• External pilot oil supply with internal return, the Y line on the manifold is dropped
• 220 l/min nominal flow in size 25, up to 870 l/min with the corresponding pressure drop
• Version without pressure reducing valve in the pilot stage, for an already controlled pilot pressure
• Spool symbol E with three switching positions across four ports, concealed manual override
• 20.73 kg weight, command value ±10 V, NBR seals for HL hydraulic fluid

Applications

The version suits power units with a central pilot circuit, for instance in press lines and test rigs. Internal return assumes a tank channel with low back pressure. UKCA conformity to SI2016/1091 is stated in the manufacturer catalogue.
