FAQ;

1. How to calibrate a 4WREE valve?
Connect a flow meter or pressure gauge to the valve’s output, apply the minimum (4 mA/0 V) and maximum (20 mA/10 V) control signals, and adjust the zero and span potentiometers (on the amplifier) to match the desired flow/pressure.

2. How often should 4WREE valves be calibrated?
Calibrate annually (or 2000 operating hours) to maintain precision, or if performance degradation is detected (e.g., inconsistent flow).

3. Can calibration be performed on-site, or is factory calibration required?
On-site calibration is possible with standard test equipment; factory calibration is recommended for critical applications requiring high accuracy.

4. What if the hydraulic system experiences pressure spikes?
Install a surge suppressor or accumulator in the system to absorb pressure spikes (limit spikes to ≤110% of the valve’s maximum operating pressure).

5. Can 4WREE valves be used in marine applications?
Marine-grade models (with corrosion-resistant coatings) are available for saltwater environments; ensure compliance with marine safety standards (e.g., DNV GL).
