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.

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.
