This manual details the overview, technical specs, selection data, installation, operation, debugging and maintenance of Rich RQIV/RQMIV electric actuators.
The RQIV/RQMIV series electric actuators are smart, non‑intrusive devices with a graphic LCD that displays torque, valve position, limits and alarms. They feature automatic protection, explosion‑proof design (ExdIICT4) and can be configured for field‑bus communication, making them suitable for oil, power, metallurgy and water‑treatment industries.
The document provides comprehensive information on technical parameters, selection tables, mechanical interfaces, installation procedures, operation modes (manual, local, remote), diagnostics, and optional functions such as inertia braking, electronic lock and battery backup for position retention. This manual is written in Chinese.
