Proportional Directional Valve 4WRTE16E1-220P-4X/6EG24K31/A1M - Bosch Rexroth R901551078

Shorter cycle times call for more oil, not necessarily for a bigger manifold. The 4WRTE16E1-220P-4X stays with size 16 and the ISO 4401-07-07-0-05 pattern yet lifts nominal flow to 220 l/min at operating pressures to 350 bar.

Benefits

• 220 l/min nominal flow without moving up to size 25 or 32, range maximum flow 460 l/min.
• Internal position feedback keeps the relation of command to spool travel stable over service life.
• Plus or minus 10 V command into on-board electronics, 24 VDC supply at a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol E1 with a fine control range around centre, three switching positions, four ports.
• External pilot oil supply and external return, weight 11.8 kg, NBR seals.

Applications

The build sits on presses with short cycles, on lifting axes and on materials testing machines with high traverse speed. Higher nominal flow cuts the rapid traverse time while the fine control range stays available for positioning. Hydraulic fluid is mineral oil of class HL.
