Proportional Directional Valve 4WRPDH6C4B25P-2X/M/24ND6T - Bosch Rexroth R901561087

An axis switching between rapid traverse plus fine infeed needs both from the same spool. The 4WRPDH6C4B25P-2X/M/24ND6T provides 25 l/min rated flow, opens to 41 l/min at peak, controls through internal spool position feedback.

Benefits

• 25 l/min rated flow with headroom to 41 l/min maximum flow in size 6.
• Spool symbol C4 across 4 switching positions with 4 ports, linear fine control range from the position feedback.
• Directly actuated, which removes every demand on a minimum pilot pressure in the system.
• Command value either plus minus 10 V DC or 4 to 20 mA, 24 V DC supply through the 12-pole connector (11 + PE).
• Operating pressure up to 350 bar, ISO 4401-03-02-0-05, NBR seals, HL fluid, 3.5 kg.

Technical data

Applications

Typical duties are infeed axes on grinding machines, milling machines, clamping circuits under controlled force, feed drives on special purpose machinery. The 25 l/min spool hits the band where a 40 l/min stage already resolves too coarsely in part load. Stages of 15 as well as 40 l/min are available in the range for the same subplate.
