Quarter Turn vs Multi Turn Actuators – Which One Should You Choose?

Introduction

Selecting the right actuator is critical for efficient valve operation. The two most common types are quarter turn actuators and multi turn actuators. Understanding the difference helps industries make smarter decisions.

What is a Quarter Turn Actuator?

A quarter turn actuator rotates the valve by 90 degrees to open or close it.

Best For:

• Ball valves

• Butterfly valves

• Quick shut-off applications

Advantages:

• Fast operation

• Compact size

• Cost-effective

What is a Multi Turn Actuator?

A multi turn actuator rotates multiple times to operate the valve.

Best For:

• Gate valves

• Globe valves

• Control valves

Advantages:

• High torque output

• Precise control

• Suitable for heavy-duty operations

Key Differences

Feature Quarter Turn Multi Turn

Rotation 90° Multiple turns

Speed Fast Moderate

Torque Medium High

Applications Ball/Butterfly Gate/Globe

Which One Should You Choose?

Choose Quarter Turn if:

• You need fast operation

• Space is limited

• Application is simple

Choose Multi Turn if:

• High torque is required

• Precision control is critical

• Heavy-duty valves are used
