This article introduces butterfly valve actuators, which drive valve disc rotation for pipeline on‑off and flow regulation. It covers working principles, electric/pneumatic types, five key selection parameters, industry applications and common faults. It highlights torque‑curve‑based sizing and ISO 5211 mounting interface verification.

Learn differences among part‑turn, linear‑stroke and multi‑turn electric actuators. This guide covers matching valves, torque‑thrust calculation, 5‑step selection process and typical pitfalls for your industrial actuator applications.

Learn about electric actuator response speed, internal and external influencing factors and key selection points, to select suitable actuators for valve automation projects and ensure efficient and stable system operation.

Valve Actuator Wiring describes wiring, commissioning and troubleshooting for electric valve actuators, guiding technicians to adopt standard wiring for stable industrial control.
