R900597132 DR10-5-5X/315YM German Rexroth stacked pressure reducing valve

Frequently Asked Questions (FAQ) for Rexroth DR 10-5-5X/315YM (R900597132)

Q1: What is the main function of this valve?

A:​ It is a proportional pressure reducing valve. It electronically controls and maintains a lower, stable pressure in a specific branch of a hydraulic circuit, independent of the main system pressure.

Q2: What does "315YM" in the model number mean?

A:​ 315​ indicates the maximum adjustable reduced pressure​ is 315 bar. Y​ means it has a proportional solenoid, and M​ specifies the type of solenoid coil/electronics (typically 24V DC with onboard electronics for PWM control).

Q3: How is this valve controlled?

A:​ It is controlled by a Pulse-Width Modulation (PWM)​ signal, typically 24V DC, from a compatible proportional amplifier or programmable logic controller (PLC) output card.

Q4: How is it installed into a system?

A:​ It is a sandwich or stacked valve. It mounts between a NG10 subplate​ (e.g., Rexroth RE 10-5 series) and another valve or cover plate, forming a modular manifold block.

Q5: What is the nominal flow rate?

A:​ The nominal flow is approximately 80 liters per minute. The actual usable flow depends on the pressure drop across the valve. Refer to the performance curves in the datasheet for details.
