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.

Technical data

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.
