Industries

Why are they Important?

ATEX-rated actuators are important because they enable safe and reliable valve automation in hazardous environments where explosive gases, vapours, or dust may be present. In these settings, a standard actuator could produce sparks, heat, or electrical faults that might ignite the atmosphere, leading to catastrophic incidents. ATEX-rated actuators are specifically designed and certified to prevent this risk, ensuring compliance with strict European safety regulations.

They allow industries such as oil and gas, petrochemicals, pharmaceuticals, and food processing to maintain efficient, automated control of their processes without compromising safety. By combining robust construction, certified protection, and reliable performance, ATEX-rated actuators protect both people and assets while supporting smooth and continuous operations in some of the most demanding environments.

Where would you find them?

You would find ATEX-rated actuators in industrial facilities where valves or equipment must be operated within hazardous zones that carry a risk of explosion. Common locations include oil and gas refineries, offshore drilling platforms, petrochemical plants, and chemical manufacturing facilities handling volatile substances.

They are also used in pharmaceutical production sites where flammable solvents are present, food and beverage processing plants with combustible dust, grain storage and milling facilities, wastewater treatment plants with methane-rich environments, and mining operations where explosive gases or dust may accumulate. In all these applications, ATEX-rated actuators provide safe, compliant, and dependable automation in conditions where standard actuators could pose a serious safety hazard.
