Proportional Directional Valve 4WRPEH6CB12L-3X/M/24L1 - Bosch Rexroth R901478983

Small feed and clamping axes need an unambiguous rest state in a fault. The 4WRPEH6CB12L brings one along as a fourth switching position for safety shut-down, working at 12 l/min nominal flow, up to 22 l/min maximum flow and 350 bar. Its digital IO-Link port carries command value and diagnostics on the same line, so a 5-pole M12 connector with A coding is enough.

Benefits

• Fourth switching position as a fail-safe, the axis moves to a defined state in a fault
• 12 l/min nominal flow, up to 22 l/min maximum flow at 350 bar
• IO-Link instead of an analogue signal, command value and diagnostic data run digitally over one 5-pole M12 connector, A coding
• Spool symbol C with four ports, hole pattern ISO 4401-03-02-0-05 for size 6
• On-board electronics with internal spool position feedback, 24 VDC supply
• Only 2.96 kg unit weight, NBR seals, HL hydraulic fluid, RoHS conformity to 2011/65/EU

Application

The valve fits compact handling axes, clamping fixtures and test set-ups where space is short and the controller already has an IO-Link master. Parameters can be read and changed over IO-Link during operation without removing the valve. In many circuits the fail-safe position replaces an extra shut-off valve.
