Proportional Directional Valve 4WRPDH6C4B02L-2X/M/24TD6S - Bosch Rexroth R901573182

A cylinder meant to travel a few millimetres per second overwhelms a large valve. The 4WRPDH6C4B02L-2X therefore works at 2 l/min nominal flow and resolves the command range across that small volume, at operating pressures to 350 bar.

Benefits

• 2 l/min nominal flow spreads the entire command range over a very small volume of oil.
• Direct actuation without a pilot stage, so the valve works without a pilot circuit of its own.
• Four switching positions with spool symbol C4, plus internal spool position feedback.
• Command signal either plus or minus 10 VDC or 4...20 mA, 24 VDC supply, 12-pole connector (11 + PE).
• Mounting pattern ISO 4401-03-02-0-05, operating pressure to 350 bar, weight 3.58 kg.

Applications

The valve sits on fine infeed units of grinding machines, on test cylinders and on clamping axes with short stroke. Being direct actuated, it needs no minimum pilot pressure and stays controllable at low system pressure. NBR seals match mineral oil of class HL.
