Frequently Asked Questions (FAQ) for DR 20-5-5X/100YM (Order Code: R900597283)
Q1: What is the main application of this valve?
A: This valve is a medium-flow proportional pressure reducing valve. It is primarily used to provide precise, electronically controlled lower pressure in a specific branch of a hydraulic system, independent of the main system pressure. Common applications include machine tool clamping circuits, tension control systems, and as a pilot pressure source for other control valves.
Q2: What does the "100YM" designation mean?
A: The designation breaks down as follows:
100: The maximum adjustable reduced pressure is 100 bar.
Y: The valve is operated by a proportional solenoid.
M: The solenoid includes integrated On-Board Electronics (OBE), allowing for direct PWM signal control.
Q3: How is this model different from the DR 20-5-5X/200YM?
A: The key difference is the maximum controlled pressure.
This model (100YM) is set for a maximum of 100 bar.
The 200YM model can be set up to 200 bar.
Both share the same NG20 size, flow capacity, and control method. The choice depends on the required force/pressure in the application.
Q4: How do I control this valve?
A: Control is achieved using a standard PWM (Pulse Width Modulation) signal, typically 24V DC. The valve's integrated electronics (OBE) allow it to connect directly to a PLC's PWM output or a compatible motion controller without an external analog amplifier.
Q5: How is the valve installed in a system?
A: It is a stacked (or sandwich) valve. It installs directly between an NG20 interface subplate (mounting surface per ISO 7368) and another valve or a cover plate, creating a compact, modular valve manifold.
Q6: What is the flow capacity?
A: As an NG20 size valve, it has a nominal flow rate of approximately 250 liters per minute. The actual usable flow for a specific application depends on the acceptable pressure drop, which can be verified from the official performance curves.
