Proportional Directional Valve 4WRZ25E325-7X/6EG24N9K4/D3M - Bosch Rexroth R900712186

In densely populated manifolds the P and T channels cannot always be tapped for pilot control as well. The 4WRZ25E325-7X/6EG24N9K4/D3M therefore takes pilot oil externally, drains it externally and controls 325 l/min nominal flow.

Benefits

• Pilot control led fully outside, the P and T channels stay reserved for the remaining functions of the manifold.
• Pressure reducing valve inside the valve, the external source does not have to be set to pilot pressure.
• 325 l/min nominal flow, flow up to 870 l/min, spool symbol E in size 25.
• 20.45 kg weight, 350 bar maximum operating pressure, ISO 4401-08-08-0-05 pattern.
• Concealed auxiliary actuation, 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

This version is used on collective manifolds that combine several axes and auxiliary functions. The external X and Y ports relieve the internal channels of the block. The axis itself is controlled through an external amplifier.
