Proportional Directional Valve 4WRTE25W8-220L-4X/6EG24EK31/F1M - Bosch Rexroth R901005994

Around the centre position it becomes clear how finely a valve really works, because the load moves only a few millimetres per second there. Thanks to internal position control this 4WRTE keeps the opening stable in that range while providing 220 l/min nominal flow at 350 bar overall.

Benefits

• Internal position control stabilises the opening even at small commands near centre.
• 220 l/min nominal flow for the fast phase, up to 870 l/min maximum.
• Internal pilot supply with external return keeps the spring chamber free of pressure.
• Linear characteristic with a 4...20 mA current command and on-board electronics.
• 350 bar operating pressure, weight 18.1 kg, ISO 4401-08-08-0-05 connection diagram.

Applications

The valve is used on axes with a gentle approach and heavy load, for example lifting tables, mould clamping units and testing machines with slow ramps. Three switching positions and four ports give the standard size 25 function. The operating medium is HL hydraulic fluid.
