Proportional Directional Valve 4WRTE16V220L-4X/6EG24ETK31/F1M - Bosch Rexroth R901404221

The fewer pipe runs a power unit needs, the faster it is built. The 4WRTE16V220L-4X/6EG24ETK31/F1M routes pilot supply and pilot return internally and therefore needs only the working ports of the subplate, at 220 l/min nominal flow and up to 350 bar.

Benefits

• Pilot oil supplied internally and returned internally, no additional pilot line required.
• 220 l/min nominal flow in size 16, series maximum 460 l/min.
• Spool symbol V, 3 switching positions, 4 ports to ISO 4401-07-07-0-05.
• 4...20 mA command, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals, HL fluid, weight 11.24 kg.

Applications

The valve suits presses, hoists and feed axes whose power unit runs without a pilot pump. A nominal flow of 220 l/min covers cylinders of larger area at moderate speed. The current interface simplifies connection to programmable controllers with an analogue output.
