Proportional Directional Valve 4WRPEH10CB100L-3X/V/24F1 - Bosch Rexroth R901558020

Long signal lines in a machine environment argue for a current signal rather than a voltage. The 4WRPEH10CB100L-3X/V/24F1 therefore works with a 4 to 20 mA setpoint and passes 100 l/min nominal flow at a maximum of 350 bar operating pressure.

Benefits

• Analogue setpoint 4 to 20 mA, a broken wire shows up as a signal value of zero.
• 100 l/min nominal flow at 350 bar maximum operating pressure, size 10.
• Spool symbol C with four switching positions and four ports.
• On-board electronics with internal spool position feedback, supply 24 VDC.
• FKM seals, HL hydraulic fluid, 6.7 kg, mounting pattern ISO 4401-05-04-0-05.

Applications

The valve is used on axes whose controller sits some distance away and connects over longer cables. The current signal stays stable across that run and reports a cable fault as a value below 4 mA. Connection is through a 7-pole connector (6 + PE) to EN 175201-804.
