Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901012982

A simple interface saves work in the cabinet: this valve handles the standard ±10 V command value directly and turns it into 360 l/min nominal flow.

Key benefits

• ±10 V command value straight from the controller analog output, with no intermediate module.
• 360 l/min nominal flow at a maximum flow of 1600 l/min.
• Internal pilot oil supply, external pilot oil return, which keeps the pilot valve independent of tank pressure.
• Spool symbol W8 in 3 switching positions on 4 ports to ISO 4401-10-09-0-05.
• 44.24 kg, integrated pressure reducing valve, operating pressure to 350 bar, HL hydraulic fluid.

Applications

Presses, hoisting gear and plastics machinery whose controllers provide standard analog outputs are the usual installation. Internal pilot pickup cuts piping work, while the external return safeguards operation against tank back pressure. Seals are made of NBR.
