Partial rotary electric actuators, collectively known as the Q series actuators, are driving devices that enable valves to achieve opening, closing, and regulating control. This series of actuators features comprehensive functions, reliable performance, advanced control systems, compact size, lightweight, and easy operation and maintenance.

The Q series actuators are suitable for valves such as butterfly valves, ball valves, plug valves, and dampers that require 90° rotation. They offer remote control, centralized control, and automatic control for valves, and are widely used in industries including power, metallurgy, petroleum, chemical, wastewater treatment, and agricultural irrigation.

This series of standard products meets the requirements of GB/T24923-2010 "Technical Conditions for Electric Actuators of Standard Valves."

This series of explosion-proof products meets the requirements of GB3836.1-2010 "Explosive Atmospheres - Part 1: General Requirements," GB3836.2-2010 "Explosive Atmospheres - Part 2: Equipment Protected by a Flameproof Enclosure 'd'," and GB/T24922-2010 "Technical Conditions for Explosion-Proof Electric Valves."
