Yes, integrated electronics (IPE) models include short-circuit protection, which shuts down the coil if a short is detected, preventing damage.
Shielded cables are recommended to reduce electromagnetic interference (EMI), especially in industrial environments with high electrical noise. Ground the shield at one end only.
Fluid temperature should be between -20°C and +60°C (-4°F to +140°F); temperatures above 60°C may accelerate seal wear and reduce fluid viscosity.
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.
Yes, a 25 μm absolute filter (β100 ≥ 75) is mandatory in the supply line to prevent contamination of the valve's internal components.
Yes, water contamination (exceeding 0.1%) can cause corrosion, seal degradation, and clogging. Use water-separating filters and monitor fluid moisture levels.
