FAQ:

1. Can 4WREE valves operate in cold environments (below -20°C)?
For temperatures below -20°C, use low-temperature hydraulic fluid (ISO VG 10) and heated reservoirs to prevent fluid thickening. Some models offer cold-start protection as an option.

2. How to protect 4WREE valves from dust and debris in harsh environments?
Use IP67-rated protective covers, install the valve in a sealed enclosure, and regularly clean the valve body and solenoid coils.

3. Can 4WREE valves withstand high vibration (e.g., in construction equipment)?
Yes, they are designed to withstand vibration up to 10 g (10-2000 Hz) when mounted with vibration-damping washers.

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).
