FAQ:

1. How does fluid viscosity affect valve performance?
Optimal viscosity is 20-40 mm²/s (cSt). Viscosity below 10 mm²/s may cause leakage, while viscosity above 100 mm²/s may increase pressure drop and reduce response time.

2. Do 4WREE valves require a filter in the supply line?
Yes, a 25 μm absolute filter (β100 ≥ 75) is mandatory in the supply line to prevent contamination of the valve’s internal components.

3. Can water-contaminated fluid damage 4WREE valves?
Yes, water contamination (exceeding 0.1%) can cause corrosion, seal degradation, and clogging. Use water-separating filters and monitor fluid moisture levels.

4. What is the maximum allowable particle count in the fluid?
Follow ISO 4406 Class 18/16/13 (maximum 1300 particles ≥4 μm, 160 particles ≥6 μm, 20 particles ≥14 μm per mL).

Safety & Compliance

5. Do 4WREE valves comply with CE standards?
Yes, all 4WREE valves meet CE requirements for electromagnetic compatibility (EMC) and machinery safety (Directive 2006/42/EC).
