Frequently Asked Questions

What is the advantage of a Wandfluh proportional valve?
A Wandfluh proportional valve controls hydraulic flow continuously and proportionally with the input signal (0-10V or 4-20mA), enabling smooth and precise motion control without jerky actions. This reduces wear and increases process safety.
Which amplifier card do I need for a Wandfluh proportional valve?
Wandfluh supplies matching electronic amplifier cards (HACD, DACPQ series) for each proportional valve. The choice depends on the valve type (1- or 2-spool), the desired control range, and any feedback signal present. Contact us for the correct matching.
Are Wandfluh valves CETOP-compatible?
Yes, Wandfluh directional valves are available in CETOP 3 (NG6) and CETOP 5 (NG10) mounting faces, guaranteeing direct interchangeability with valves from other manufacturers on CETOP mounting surfaces.
What is the maximum working pressure of Wandfluh valves?
Wandfluh valves are standard available for working pressures up to 350 bar for most series. Special high-pressure versions are available up to 450 bar for compact hydraulic systems. Consult the specification table for your series.
How do I calibrate a Wandfluh proportional valve?
Calibration of a Wandfluh proportional valve is performed via the adjustments on the matching amplifier card: set zero point, gain factor, and threshold according to the setup manual. For accurate calibration, a hydraulic test block with pressure and flow measurement is recommended.
