Multiple Electric Actuator
Multi-Turn Electric Actuator
The multi-turn small electric valve actuator is a new product extended from the small-di
What is quarter turn actuator?
A Quarter-Turn Actuator is designed to operate valves that require a 90-degree turn to move from the fully-open to the fully-closed position—or vice versa. Simply put, it's all about the quick pivot, no dilly-dallying.
What are four types of electrical actuators?
1. Linear Electric Actuators
Characteristics:
Linear Motion: Directly produces linear motion in a push or pull action.
Precision: High level of control and accuracy.
Ideal For:
Sluice Gates: In water treatment facilities.
Lifting Mechanisms: In material handling sectors.
Noteworthy Features:
Easy to integrate with control systems for automated or manual operations.
2. Rotary Electric Actuators
Characteristics:
Rotational Motion: Offers angular motion typically up to 360 degrees.
Versatile: Suitable for various applications, often adjustable for different angles.
Ideal For:
Ball Valves: In chemical processing plants.
Butterfly Valves: In HVAC systems.
Noteworthy Features:
Usually compact and easy to install.
3. Quarter-Turn Electric Actuators
Characteristics:
90-Degree Turn: Specialized for applications requiring a quick quarter-turn.
Efficient: Swift and precise operations.
Ideal For:
Plug Valves: In oil and gas pipelines.
Dampers: In ventilation systems.
Noteworthy Features:
Often comes with built-in positioners and sensors for feedback control.
4. Multi-Turn Electric Actuators
Characteristics:
Multiple Rotations: Designed for valves that require multiple turns to reach full open or close positions.
High Torque: Ideal for heavy-duty applications.
Ideal For:
Gate Valves: In hydropower stations.
Globe Valves: In steam systems.
Noteworthy Features:
Highly customizable with various control options.
What is the difference between quarter turn and multi turn actuators?
Range of Motion: A Tale of 90 Degrees vs Multiple Turns
Quarter-Turn Actuators
Range: Limited to a 90-degree turn.
Action: Ideal for opening and closing valves in a snap, literally with a quarter turn.
Multi-Turn Actuators
Range: Multiple 360-degree turns, offering a broader range of motion.
Action: Useful for valves that require more rotations to reach their fully opened or closed positions.
Applications: Where Each Finds its Home Turf
Quarter-Turn Actuators
Valve Types: Mainly used for ball, plug, and butterfly valves.
Industries: Widely seen in HVAC systems, chemical plants, and water treatment facilities.
Multi-Turn Actuators
Valve Types: Commonly employed for gate, globe, and pinch valves.
Industries: Often used in power plants, dams, and any other application requiring a high level of torque over several turns.
Speed & Efficiency: Quick Sprints vs Steady Marathons
Quarter-Turn Actuators
Speed: Faster operations due to limited range.
Efficiency: Consumes less energy for short, quick actions.
Multi-Turn Actuators
Speed: Generally slower due to multiple rotations needed.
Efficiency: May consume more energy but can generate higher torque.
Control & Feedback: The Brains Behind the Brawn
Quarter-Turn Actuators
Control: Often comes with built-in positioners and sensors for precise control.
Multi-Turn Actuators
Control: Usually feature more sophisticated control options to monitor multiple turns, making them suitable for complex applications.
