Proportional Directional Valve 4WRDE16E220L-6X/MPTWG/24A5 - Bosch Rexroth R901479145

The 4WRDE16E220L-6X/MPTWG/24A5 is the E spool version with the fewest ports: pilot supply and pilot return run inside the valve, so the manifold needs only P, T, A and B. At 220 l/min nominal flow with peaks of up to 460 l/min the on-board electronics correct the spool position through the transducer.

Benefits

• Only four main ports are needed on the manifold, since pilot oil enters and leaves internally.
• 220 l/min nominal flow with a maximum flow rate of 460 l/min.
• Spool symbol E with three switching positions at an operating pressure of up to 350 bar.
• Closed loop main spool with an internal position transducer and a ±10 V command value.
• Valve weight 10.5 kg on an ISO 4401-07-07-0-05 mounting pattern.

Application

The variant fits series power units whose working pressure stays reliably above pilot pressure, for example in presses and lifting equipment. The NBR seals are rated for mineral oil HL. Connection is via a subplate to ISO 4401-07-07-0-05.
