Proportional Directional Valve 4WRTE16E150P-4X/6EG24K31/A1M - Bosch Rexroth R901551264

Accumulator circuits run at strongly varying system pressure, yet the pilot stage still needs a steady supply. The 4WRTE16E150P-4X/6EG24K31/A1M is therefore fed from outside and drained to the outside, metering 150 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• External pilot oil supply and external pilot oil return, constant pilot pressure as accumulator pressure falls.
• 150 l/min nominal flow, maximum flow 460 l/min in size 16.
• Linear characteristic curve with a fine control range for smooth transitions between rapid traverse and positioning.
• Spool symbol E, operating pressure up to 350 bar, connection diagram ISO 4401-07-07-0-05.
• ±10 V command value, 24 VDC through a 7-pole (6 + PE) connector to EN 175201-804, 11.8 kg weight.

Applications

The valve is used in accumulator hydraulics of presses, shears and emergency lowering equipment. Because pilot pressure comes from its own circuit, loop gain stays the same throughout accumulator discharge. At 150 l/min even large cylinder areas move briskly.
