Proportional Directional Valve 4WRZ25E325-7X/6EG24N9TK4/D3M - Bosch Rexroth R900709344

When tuning an axis it helps to be able to set and measure pilot pressure from outside. The 4WRZ25E325-7X/6EG24N9TK4/D3M permits that through its external supply and additionally limits pressure inside the valve, at 325 l/min nominal flow.

Benefits

• External supply for pilot pressure, measuring point and adjustment sit outside the valve.
• Additional limiting by the built-in pressure reducing valve, a supply pressure set too high does not reach the pilot stage.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol E in size 25.
• 20.4 kg weight, 350 bar maximum operating pressure, internal return, NBR seals.
• Concealed auxiliary actuation, commanded at 24 VDC through an external amplifier.

Applications

This combination is meant for test rigs and for plants that are measured during commissioning. Pilot pressure can be changed on the external branch without touching the working circuit. The return uses the tank channel of the connection pattern.
