Proportional Directional Valve 4WRZE32W9-360-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R901194990

A separate pilot circuit costs a pump, piping and space. This pilot-operated size 32 4WRZE proportional directional valve draws pilot oil internally from the main circuit and includes the pressure reducing valve. It meters 360 l/min nominal, passes up to 1600 l/min and works to 350 bar.

Benefits

• Internal pilot oil supply with an integrated pressure reducing valve removes the need for a separate pilot pump, pilot return is external.
• 360 l/min nominal and up to 1600 l/min maximum flow at 350 bar operating pressure.
• ±10 V command straight into the on-board electronics from an axis controller or analogue card.
• FKM seals instead of NBR, rated for HL hydraulic fluid.
• Concealed manual override supports commissioning and fault finding without power.
• ISO 4401-10-09-0-05 connection pattern, UKCA conformity under SI2016/1091.

Applications

Intended for presses, hydraulic power units and test rigs with high flow where no dedicated pilot circuit is to be built. The valve weighs 44.04 kg and is mounted on a subplate. Characteristic curves and pilot pressure limits are given in the data sheet.
