Proportional Directional Valve 4WRTE16W8-220L-4X/6EG24K31/A1M - Bosch Rexroth R901516188

Running two cylinders in step only works if both axes have identical actuators and identical pilot conditions. The 4WRTE16W8-220L-4X/6EG24K31/A1M is fed from a shared external pilot circuit and meters 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• External pilot oil supply and external pilot oil return, the same conditions for every axis in a group.
• 220 l/min nominal flow, maximum flow 460 l/min in size 16.
• Spool symbol W8 with a linear characteristic curve, 3 switching positions and 4 ports.
• ±10 V command value on the on-board electronics, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.
• Operating pressure up to 350 bar, connection diagram ISO 4401-07-07-0-05, 11.1 kg weight.

Technical data

Applications

The valve serves synchronised axes on gantry presses, lifting platforms and lock gates. A shared pilot rail supplies every pilot stage at the same pressure and keeps the axes behaving alike. At 220 l/min large piston areas move in step.
