This document describes the features and advantages of the electromagnetic directional control valve and Vickers® directional control valve produced by Flowserve.
The Vickers DG4V-3 series includes a high‑performance model (DG4V-3) and a standard‑performance model (DG4V-3S). Both are four‑way, four‑port solenoid‑controlled direction control valves designed for industrial hydraulic systems. The manual describes the valve’s functional symbols, model coding, working data, performance data, and installation dimensions.
Installation guidance covers base plates, connecting plates, electrical connectors, bolt specifications, and recommended mounting practices. Additional sections provide spare‑part numbers, seal‑kit information, coil options, temperature limits, oil cleanliness requirements, and ordering procedures. This manual is written in Chinese.
