Proportional Directional Valve 4WRTE16V220L-4X/6EG24EK31/F1M - Bosch Rexroth R901562790

In large presses and power units there are often twenty metres of cable between the control card and the valve. The 4WRTE16V220L-4X/6EG24EK31/F1M therefore accepts a 4...20 mA command and uses it to meter 220 l/min nominal flow at operating pressures up to 350 bar. Pilot oil is supplied internally, the pilot return is led away externally.

Benefits

• A 4...20 mA command stays immune to voltage drop and pickup over long cable runs.
• 220 l/min nominal flow in size 16, the series carries up to 460 l/min.
• Internal pilot oil supply saves a separate pilot pump, the return goes externally to tank.
• Spool symbol V with 3 switching positions and 4 ports, mounting pattern ISO 4401-07-07-0-05.
• On-board electronics at a 7-pole connector (6 + PE) to EN 175201-804, 24 VDC supply, weight 11.26 kg.

Applications

The valve controls advance and retract on medium duty presses, lifting gear and clamping cylinders. Because the command travels as a current, it suits installations with long cable routes or heavy electrical interference. The NBR seals match mineral oil of class HL.
