Proportional Directional Valve 4WRZE10W9-25-7X/6EG24N9ETK31/A1V - Bosch Rexroth R901179154

On axes with a small cylinder, fine resolution decides positioning accuracy. The 4WRZE10W9-25-7X/6EG24N9ETK31/A1V passes 25 l/min nominal flow in size 10, works up to 315 bar and can be checked by hand through the concealed auxiliary actuation without any control signal.

Benefits

• 25 l/min nominal flow, fine resolution against a 170 l/min maximum rating
• Concealed auxiliary actuation allows a function check without an electrical signal
• FKM seals, suitable for higher oil temperatures and demanding media
• Supplied without pressure reducing valve, pilot pressure comes from the main circuit
• Spool symbol W9, internal pilot oil supply and internal return

Applications

Typical in test rigs, clamping devices and rotary table drives with small cylinders. The ISO 4401-05-05-0-05 interface corresponds to size 10. Technical details are given in the data sheet for pilot-operated proportional directional valves RE 29115.
