Proportional Directional Valve 4WRPDH6C3B40P-2X/M/24SD6U - Bosch Rexroth R901157481

Raising a load plus holding it are two entirely different operating states for a lifting axis. The 4WRPDH6C3B40P-2X/M/24SD6U serves both, releasing up to 50 l/min while raising, working inside the fine control range of its characteristic while holding.

Benefits

• 40 l/min rated flow for the lift, 50 l/min maximum, operating pressure up to 350 bar.
• Fine control range on a linear characteristic for quiet holding of the position.
• Internal spool position feedback corrects the opening as load at the cylinder changes.
• Spool symbol C3 with 4 switching positions across 4 ports, directly actuated without pilot oil.
• Command value plus minus 10 V DC or 4 to 20 mA, 24 V DC, ISO 4401-03-02-0-05, NBR seals, 3.56 kg.

Technical data

Applications

Duties run from lift tables, scissor platforms, through to adjusting cylinders in plant engineering where load hangs on the valve permanently. Safety functions such as a load holding valve remain the task of a separate component in the circuit. This control valve shapes the motion, it does not secure the load.
