Proportional Directional Valve 4WRPDH6C4B25P-2X/V/24TD6T - Bosch Rexroth R901440453

Where a feed or clamping axis in size 6 has to travel smoothly, control quality decides the result. The 4WRPDH6C4B25P-2X/V/24TD6T works direct actuated, measures spool position internally and provides 25 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Direct actuated in size 6, so no separate pilot circuit is required and response depends on the on-board electronics alone.
• Internal spool position feedback keeps the characteristic curve repeatable even when load changes.
• 25 l/min nominal flow, 41 l/min maximum, operating pressure up to 350 bar.
• Symbol C4 with four switching positions, linear characteristic with a fine control range for slow starts.
• Command value either ±10 V DC or 4 to 20 mA, supplied with 24 V DC through a 12-pole connector (11 + PE).
• FKM seals, HL hydraulic fluid, weight 3.3 kg, mounting pattern ISO 4401-03-02-0-05.

Technical data

Applications

The valve suits test benches, clamping fixtures and small feed axes where the envelope allows size 6 only. Its fine control range permits creep speeds without the axis jerking. Four switching positions additionally provide a defined intermediate state.
