Proportional Directional Valve 4WRTE16E220L-4X/6EG24ETK31/A1M - Bosch Rexroth R901418231

Every additional pilot line means another fitting on the manifold. The 4WRTE16E220L-4X/6EG24ETK31/A1M routes pilot oil supply and return internally and therefore manages with the four main ports, at 220 l/min nominal flow.

Benefits

• Internal pilot oil supply and return, no X and Y fittings required.
• 220 l/min nominal flow in size 16, up to 460 l/min maximum.
• Command value ±10 V, on-board electronics at 24 V DC inside the valve.
• Spool symbol E with a linear characteristic and internal spool position feedback.
• 11.04 kg weight, 350 bar maximum operating pressure, connection diagram ISO 4401-07-07-0-05.

Applications

The internally piloted version is the usual choice in circuits whose system pressure stays above the minimum pilot pressure. It shortens assembly time at the manifold and reduces the number of possible leak points. The intended hydraulic fluid is HL and the seals are NBR.
