Proportional Directional Valve 4WRTEM16E220L-4X/6EG24K31/F1M - Bosch Rexroth R901583896

Where an axis has to reach a position and hold it under load, spool feedback decides the result. The 4WRTEM16E220L works with internal spool position feedback, releases up to 460 l/min and withstands 350 bar operating pressure. On-board electronics process the 4...20 mA command value and close the loop on spool position, so a separate amplifier card is not needed.

Benefits

• Internal spool position feedback gives closed-loop spool travel instead of plain current control
• 460 l/min maximum flow in size 16 at up to 350 bar
• On-board electronics at the valve, 4...20 mA command value through a 7-pole connector (6 + PE) to EN 175201-804
• Spool symbol E with three switching positions and four ports
• Subplate mounting to ISO 4401-07-07-0-05, external pilot oil supply and external return
• NBR seals for HL hydraulic fluid, 16.94 kg unit weight

Technical data

Application

The valve is intended for position-controlled axes on forming machines, test rigs and injection moulding machines where the cylinder has to follow a path or a force profile. A 4...20 mA current signal stays unaffected by voltage drop over longer cable runs. Pilot oil is supplied and drained externally.
