Proportional Directional Valve 4WRPDH6C4B15P-2X/M/24SD6U - Bosch Rexroth R901358982

In joining work it is the steady force profile over travel that counts, never the speed. The 4WRPDH6C4B15P-2X/M/24SD6U caps flow at 15 l/min rated, keeping the spool quiet through internal feedback.

Benefits

• 15 l/min rated flow with 30 l/min maximum, so the axis stays slow even at full command.
• Internal spool position feedback steadies the opening as counterforce at the workpiece rises.
• Spool symbol C4 with 4 switching positions across 4 ports, linear fine control range.
• Command value plus minus 10 V DC or 4 to 20 mA, 24 V DC supply on the 12-pole connector (11 + PE).
• Directly actuated without pilot oil, 350 bar, ISO 4401-03-02-0-05, NBR seals, 3.57 kg.

Applications

Applications are press-fit axes, riveting axes, welding guns with controlled electrode force, calibration stations. Limited flow prevents the axis from slamming through as it touches the workpiece. A switching valve can be added in the same circuit for a rapid return stroke.
