FAQ
▔▔Q: How do I decode my Vickers DG4V model code to ensure a direct replacement?
A: Check the metal nameplate located on the side of the valve body. The code indicates the subplate size (e.g., 3 or 5), spool function (e.g., 2A, 0C, 6C), electrical voltage, and design series (e.g., 60 or 20).
Q: What level of oil filtration is required for reliable DG4V operation?
A: We recommend maintaining oil cleanliness at or better than ISO 4406 Class 18/16/13 (typically achieved with a 10-micron nominal inline filter) to prevent spool sticking caused by particulate contamination.
Q: Can DG4V valves operate with water-glycol hydraulic fluids?
A: Yes, provided the valve is configured with Viton (Fluorocarbon) seals and the operating fluid viscosity remains within the 16 to 360 mm2/s (cSt) specification.

FAQ
▔▔Q1: What is the difference between DG4V-3 and DG4V-3S?
A: The DG4V-3 is the standard version optimized for high flow capacity (up to 80 L/min), whereas the DG4V-3S is a high-performance/solenoid-efficient version designed for standard duty cycles and lower maximum flows (up to 40 L/min), offering lower power consumption and optimized cost-performance.
Q2: Can I replace an AC solenoid coil with a DC solenoid coil on the same valve?
A: No, you cannot simply swap AC and DC coils on the same armature tube. The physical size, coil resistance, and armature stroke configurations differ between AC and DC versions. To change the voltage type, you generally need to change the entire solenoid tube/coil assembly specified for that voltage, or order the matching valve model.
