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.

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.
