Proportional Directional Valve 4WRTE16E1-220L-4X/6EG24K31/F1M - Bosch Rexroth R901505349

In port and waterway engineering a hundred metres of cable soon separate the control room from the valve, while the pilot station sits in the machine house. The 4WRTE16E1-220L-4X/6EG24K31/F1M matches that layout, accepts 4...20 mA and meters 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• 4...20 mA command value, low loss transmission over very long cable routes.
• External pilot oil supply and external pilot oil return, matched to a central pilot station.
• 220 l/min nominal flow, maximum flow 460 l/min in size 16.
• Spool symbol E1 with a linear characteristic curve, operating pressure up to 350 bar.
• Connection diagram ISO 4401-07-07-0-05, 11.04 kg weight, NBR seals.
• On-board electronics, 24 VDC through a 7-pole (6 + PE) connector to EN 175201-804.

Applications

The valve moves weir flaps, lock gates and crane equipment whose operating station lies far from the hydraulics. The current interface stays unambiguous along the whole cable route. At 220 l/min even large lifting cylinders reach usable travel speeds.
