Proportional Directional Valve 4WRPEH6C1B24L-3X/V/24F1 - Bosch Rexroth R901545003

There are often twenty metres of cable between cabinet and valve, and a voltage signal loses level over that distance. The 4WRPEH6C1B24L-3X/V/24F1 therefore accepts 4 to 20 mA and uses it to control 24 l/min nominal flow in size 6.

Benefits

• Command value 4 to 20 mA, the current loop is insensitive to voltage drop over long cables.
• Internal spool position feedback for a defined relation between command value and opening under load.
• 24 l/min nominal flow at 350 bar maximum operating pressure in size 6.
• Spool symbol C1, four switching positions, four ports on the ISO 4401-03-02-0-05 pattern.
• FKM seals, 3.2 kg weight, 24 VDC supply, directly actuated without a pilot stage.

Applications

The valve is used on feed and positioning axes whose amplifier sits far away in the control cabinet. The current signal also allows a broken wire to be detected from the loss of the standing current. Without a pilot oil circuit, the valve can run on small power units too.
