Proportional Directional Valve 4WRPDH6C4B25P-2X/M/24SD6U - Bosch Rexroth R901450732

Between the fine 15 l/min stage plus the fast 40 l/min stage lies the band where many axes actually work. The 4WRPDH6C4B25P-2X/M/24SD6U covers it with 25 l/min rated flow, controlling up to 350 bar.

Benefits

• 25 l/min rated flow, 41 l/min maximum, a middle ground between resolution as well as speed.
• Spool symbol C4 with 4 switching positions across 4 ports, internal spool position feedback, linear characteristic.
• Directly actuated, hence independent of a pilot circuit, operating pressure up to 350 bar.
• Command value either plus minus 10 V DC or 4 to 20 mA, 24 V DC on the 12-pole connector (11 + PE).
• ISO 4401-03-02-0-05, NBR seals for HL fluid, 3.56 kg, UKCA with EMC SI2016/1091.

Applications

The band around 25 l/min suits medium feed axes, clamping cylinders running a force ramp, infeed drives on forming tools. The axis travels briskly yet stays controllable at the end stop. Since the mounting pattern matches the other stages, a later spool change needs no rework.
