Frequently Asked Questions (FAQ) for ZDR 6 DPO-4X/40YM/W80 (Order Code: R900323180)
Q1: What is a pilot-operated proportional pressure reducing valve, and how is it different from a standard DR valve?
A: This valve (ZDR) is a two-stage valve. It combines a small, fast pilot valve (the DPO section) with a larger main spool valve. The pilot valve controls the pressure to the main spool, which then meters the flow. This design provides higher flow capacity, better stability, and faster response at high flows compared to the direct-acting DR series valves, which are single-stage.
Q2: What does the full model designation "ZDR 6 DPO-4X/40YM/W80" mean?
A:
ZDR 6: Main valve series and nominal size (NG6, for high flow relative to its size).
DPO-4X: Specifies the internal pilot valve design and configuration.
40: Maximum adjustable reduced pressure is 40 bar.
Y: Proportional solenoid control.
M: On-Board Electronics (OBE) for direct PWM input.
W80: A specific factory variant code, typically indicating a special performance characteristic, production batch, or hardware revision. The exact meaning should be confirmed with the official datasheet.
Q3: Why is the reduced pressure only 40 bar on this valve?
A: This 40 bar setting is a common specification for pilot pressure applications. The valve excels at providing a very stable, precisely controlled, and clean flow of hydraulic fluid at a constant pilot pressure (typically 20-40 bar) to operate other control valves (like large directional or proportional valves) in a system. Its high-flow capability makes it ideal for supplying multiple pilot circuits.
Q4: How does the control and wiring work with the "YM" designation?
A: The "YM" designation means the integrated pilot valve has a proportional solenoid with On-Board Electronics (OBE). It is controlled by a standard 24V DC PWM signal, which can be supplied directly from a PLC or controller, simplifying installation by eliminating the need for an external analog amplifier.
Q5: How is this valve installed?
A: It is a subplate-mounted valve. It installs onto a dedicated NG6 interface subplate (mounting surface per ISO 4401) which is then piped to the system. This differs from the sandwich-style DR valves and is common for standalone, high-performance valves.
