Proportional Directional Valve 4WRTE16E220P-4X/6EG24K31/A1M - Bosch Rexroth R901540678

A cylinder of 200 mm bore needs flow, otherwise the working stroke turns into a test of patience. The 4WRTE16E220P-4X/6EG24K31/A1M delivers 220 l/min nominal flow at operating pressures up to 350 bar and keeps positioning accurate through its fine control range.

Benefits

• 220 l/min nominal flow, maximum flow 460 l/min in size 16.
• Linear characteristic curve with a fine control range, high resolution close to null.
• External pilot oil supply and external pilot oil return.
• Spool symbol E, 3 switching positions and 4 ports, connection diagram ISO 4401-07-07-0-05.
• Operating pressure up to 350 bar, ±10 V command value, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.
• NBR seals for HL hydraulic fluid, 11.1 kg weight.

Applications

The valve moves press rams, die cushions and large lifting cylinders in steel construction and forming technology. High nominal flow shortens rapid and return strokes while the fine control range keeps the approach to the end position smooth. External pilot supply suits power units with their own pilot pump.
