Proportional Directional Valve 4WRKE10E1-50L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R900744115

In cyclic material testing what matters is that every load cycle looks the same. The 4WRKE10E1-50L-3X/6EG24ETK31/A1D3M supports that with internal position feedback, 50 l/min nominal flow and a ±10 V command.

Benefits

• ±10 V command with a linear characteristic curve, the sign sets the direction of travel.
• 50 l/min nominal flow, up to 170 l/min, spool symbol E1.
• Pilot oil supplied and drained internally, the setup stays free of additional lines.
• 315 bar maximum operating pressure, ISO 4401-05-05-0-05 pattern, size 10.
• 8.33 kg, NBR seals, connected through a 7-pole (6 + PE) plug.

Applications

The valve works on material and component testing machines, oscillating cylinders and simulation rigs. Spool feedback keeps the amplitude even across many cycles. For a replacement the A1 voltage input is the decisive detail.
