Proportional Directional Valve 4WRZ16E180-7X/6EG24N9ETK4/D3M - Bosch Rexroth R901478665

If system pressure fluctuates, the behaviour of the pilot stage changes with it unless a reducing stage is present, and control quality suffers. The pilot-operated proportional directional valve 4WRZ16E180-7X/6EG24N9ETK4/D3M therefore includes a pressure reducing valve and delivers a nominal flow of 180 l/min in size 16.

Benefits

• Version with pressure reducing valve, constant pilot pressure even when system pressure varies.
• Nominal flow 180 l/min, maximum flow 460 l/min, operating pressure up to 350 bar.
• Spool symbol E, three switching positions on four ports.
• Internal pilot oil supply and internal pilot oil return, concealed auxiliary actuation.
• Electrical control with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804, weight 15.68 kg.

Technical data

Application

The valve controls feed and positioning axes in presses, test rigs and forming machines with continuous setpoints. External amplifier electronics are needed for control. The concealed auxiliary actuation allows movement during commissioning without an electrical signal.
