Proportional Directional Valve 4WRTE16V220L-4X/6EG24EK31/A1M - Bosch Rexroth R901523832

Replacing a valve should not retire the existing control card as well. The 4WRTE16V220L-4X/6EG24EK31/A1M accepts the classic plus or minus 10 V command and sets 220 l/min nominal flow with it at operating pressures up to 350 bar. Pilot oil comes internally from the main channel, the return is routed externally.

Benefits

• A plus or minus 10 V command connects straight to existing analogue cards, no new signal wiring.
• 220 l/min nominal flow at 350 bar operating pressure, series maximum 460 l/min.
• Internal pilot supply with external return relieves the pilot circuit where tank pressure is high.
• Spool symbol V, 3 switching positions, mounting pattern ISO 4401-07-07-0-05 in size 16.
• On-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804, 11.08 kg.

Applications

Typical places are forming presses, lift tables and test cylinders whose control is already built around a voltage command. Internal pilot supply allows operation without an extra pump. NBR seals with HL fluid form the standard combination for mineral oil.
