Proportional Directional Valve 4WRZE32E1-360-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R901223363

A large volume cylinder should start smoothly and stop without a pressure surge. This 4WRZE32E1-360-7X handles that task with 360 l/min nominal flow and internal pilot supply, so the power unit needs no separate pilot pump.

Key benefits

• 360 l/min nominal flow with a permitted flow of 1600 l/min leaves headroom for short rapid strokes.
• Internal pilot oil supply and internal pilot oil return save two external control lines.
• The built-in pressure reducing valve keeps the pilot pressure steady even when working pressure varies up to 350 bar.
• On-board electronics process the 4 to 20 mA current command, so no separate amplifier is needed in the cabinet.
• Concealed auxiliary actuation allows the axis to be moved if the 24 VDC supply fails.

Applications

The valve is used on hydraulic presses, injection moulding machines and lifting axes where a single cylinder takes several hundred litres per minute. The 4 to 20 mA current command stays insensitive to interference over long cable runs. FKM seals allow higher oil temperatures than NBR.
