Choosing the Right Actuator: A Comparative Guide

The valve body is only part of the solution. Selecting the correct actuator is critical for performance, safety, and efficiency. This guide compares common options for butterfly valves.

Actuator Type	Operating Principle	Key Advantages	Best Applications / Industries
Handle (Lever)	Manual quarter-turn (90°) operation. Often includes a locking mechanism or notched plate for positioning.	Simple, low cost, and reliable. Provides immediate visual feedback of valve position. No external power source required. Fast-acting for quick shutoff.	Small-diameter pipelines (typically ≤ DN300). General purpose water, air, and chemical lines. Applications requiring infrequent operation. Food & Beverage, HVAC, Water Treatment.
Gear (Worm Gear)	A manual handwheel turns a gearbox, which multiplies torque to make opening/closing large valves easier.	Significantly reduces the physical effort needed. Allows for precise control and throttling. Prevents water hammer by enabling slow operation. Self-locking design holds the disc in position.	Large-diameter valves (≥ DN250). High-pressure or high-flow systems. Municipal Waterworks, Power Plants, Shipbuilding. Any application needing slow, controlled operation.
Pneumatic	Uses compressed air to move a piston or diaphragm, which rotates the valve stem. Can be spring-return or double-acting.	Very fast and powerful actuation. High cycle life and extremely reliable. Intrinsically safe for explosive environments (no spark). Lower cost than electric actuators for large sizes.	Automated process control systems. Emergency shutdown (ESD) systems (spring-return). High-cycle applications. Chemical, Oil & Gas, Pharmaceutical.
Electric	An electric motor drives a gear train to rotate the valve stem. Can offer sophisticated control options.	Extremely precise positioning for modulation control. Ideal for remote operation where compressed air is unavailable. Easily integrates with PLC and SCADA systems. Low energy consumption when not in operation.	Remote and unmanned facilities (e.g., pipelines). Advanced automation and process control. Wastewater Treatment, Power Generation, HVAC. Applications requiring complex control logic.
