Proportional Directional Valve 4WRTEM16W6-150L-4X/6EG24K31/A1M - Bosch Rexroth R901509622

For an axis with a medium cylinder the next larger flow rating is often too coarse. The 4WRTEM16W6-150L-4X/6EG24K31/A1M therefore controls 150 l/min nominal flow in size 16 and takes its control oil from a separate circuit through X.

Benefits

• 150 l/min nominal flow, graded finely enough for medium piston areas in size 16.
• External pilot oil supply and external return for a constant control pressure over the cycle.
• Spool symbol W6 blocks in mid position and holds the axis without an extra valve.
• Plus or minus 10 V command at the on-board electronics with spool position feedback.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.5 kg, operating pressure up to 350 bar.

Technical data

Applications

The valve is found on clamping axes, on infeed movements of machine tools and on test cylinders. Because the pilot stage is fed externally, step response is kept even when system pressure falls. The series maximum flow is 460 l/min.
