Proportional Directional Valve 4WRTE25E1-220L-4X/6EG24EK31/F1V - Bosch Rexroth R901460553

The 4WRTE25E1-220L-4X/6EG24EK31/F1V uses the E1 spool, which brings its own port assignment in the centre position. At 220 l/min nominal flow and up to 870 l/min at peak the pilot stage takes its oil internally but releases it through a dedicated Y line, so back pressure in the tank cannot disturb position control.

Benefits

• Spool symbol E1 with its own port assignment in the centre position.
• 220 l/min nominal flow with a maximum flow rate of 870 l/min.
• Internal pilot oil supply with an external return, so only one additional line on the manifold.
