How to Select the Right Electric Actuator: A Technical Buyer's Guide

Selecting the wrong actuator can lead to system failure, costly downtime, and safety risks. With numerous models and specifications available, making the right choice requires a methodical approach. This guide will help you identify the critical parameters for selecting the ideal Electric Actuator for your project.

Your Electric Actuator Selection Checklist:

Valve Type and Torque/Thrust Requirements:

Quarter-Turn (90°): For ball, butterfly, plug valves. The key spec is torque (Nm or lb-in). You must know the required breakaway and running torque of the valve.

Multi-Turn: For gate, globe, rising stem valves. The key spec is thrust (Newton or lbf). You must know the required stem thrust.

Voltage and Power Supply:

Specify the available electrical supply on site (e.g., 24VDC, 110VAC, 220VAC, 380VAC, 50/60Hz). This is a fundamental requirement for compatibility.

Control Signal and Feedback:

How will you operate the actuator?

Basic: On/Off via DPDT switch.

Modulating: 4-20mA or 0-10V DC control signal for proportional positioning.

Feedback: Required signals (e.g., potentiometer, 4-20mA position transmitter, limit switches).

Environmental and Protection Conditions:

IP Rating: Determines protection against dust and moisture. (e.g., IP65 for weatherproof, IP67/68 for temporary/permanent submersion).

Temperature Range: Ensure the actuator is rated for your ambient operating temperature.

Hazardous Areas: If required, specify the necessary certifications like ATEX, IECEx for explosive atmospheres.

Speed and Duty Cycle:

How fast does the valve need to operate? Actuator speed is given in seconds per 90° or seconds per inch of stroke. Also, consider the duty cycle—standard actuators are for intermittent use, not continuous throttling.
