Proportional Directional Valve 4WRTE16V1-150L-4X/6EG24K31/A1M - Bosch Rexroth R901443976

When a servo axis is overhauled, the control loop is usually the expensive part and should be kept. The 4WRTE16V1-150L-4X/6EG24K31/A1M therefore keeps the plus or minus 10 V command and sets 150 l/min nominal flow with it at operating pressures up to 350 bar, with spool symbol V1.

Benefits

• A plus or minus 10 V command preserves the existing control loop, only the valve is replaced.
• 150 l/min nominal flow in size 16, series maximum 460 l/min.
• Spool symbol V1, 3 switching positions, 4 ports to ISO 4401-07-07-0-05.
• External pilot oil supply and external return for power units with a pilot pump.
• On-board electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804, 11.04 kg.

Applications

The valve replaces aged control valves in positioning axes, clamping units and test cylinders. At 150 l/min the response stays fine enough in the small signal range for smooth travel. NBR seals match mineral oil of class HL.
