ATEX Solenoid Valves

ATEX actuators are purpose-built to operate valves in hazardous environments where flammable gases, vapours or dust could ignite. Explosion-proof electric actuators incorporate intrinsic safety measures that limit the energy available in the event of a fault, preventing sparks or arcs from igniting flammable substances. They feature robust housings made from stainless steel or other alloys to withstand extreme temperatures, corrosive atmospheres and mechanical stress

Why are they Important?

ATEX solenoid valves are important because they are specifically engineered to operate safely in hazardous environments where explosive gases, vapours, or dust may be present. In such areas, even a small electrical spark or excessive surface temperature can trigger an ignition, so ATEX-certified solenoid valves are built with explosion-proof or intrinsically safe designs to prevent this risk. They ensure compliance with strict European ATEX directives, which is essential for meeting legal safety requirements in industries such as oil and gas, chemical processing, pharmaceuticals, and food production.

Beyond safety, these valves provide precise and reliable control over fluid or gas flow, enabling critical processes to run efficiently without compromising worker or site safety. By combining robust construction, certified safety features, and dependable performance, ATEX solenoid valves play a vital role in protecting both people and assets in high-risk applications.

Where would you find these?

You would typically find ATEX solenoid valves in industrial environments where explosive atmospheres are a risk and strict safety standards must be met. Common locations include oil and gas facilities such as offshore platforms, refineries, and fuel storage depots; chemical and petrochemical plants handling volatile substances; pharmaceutical manufacturing sites using flammable solvents; and food or beverage processing plants where combustible dust can be generated.

They are also widely used in wastewater treatment facilities, paint spray booths, grain handling and milling operations, and any other setting where gases, vapours, or dust particles could ignite under certain conditions. In all these applications, ATEX solenoid valves provide the essential function of controlling the flow of liquids or gases while preventing potential ignition sources in hazardous zones.

Frequently Asked Questions

An ATEX-rated solenoid valve is a valve designed to safely control the flow of liquids or gases in hazardous environments where explosive gases, vapours, or dust may be present, in compliance with the European ATEX Directive.

They are essential in explosive atmospheres to prevent sparks, excessive heat, or other ignition sources from causing explosions.

They are widely used in oil and gas, petrochemical, chemical, pharmaceutical, food processing, grain handling, wastewater treatment, and mining industries.

They are built with explosion-proof or intrinsically safe designs, special sealing, and certified materials to meet ATEX safety standards for hazardous areas.

They can be used in ATEX Zone 1, Zone 2 (gases/vapours), and Zone 21, Zone 22 (dust), depending on the specific certification.

Yes, many are designed with robust enclosures and high ingress protection ratings (IP65–IP67), making them suitable for outdoor hazardous environments.

They can control air, water, oil, steam, gases, and various chemicals, depending on the valve material and design.

Yes, many models feature low-power coils to reduce energy consumption while maintaining reliable performance.

They require regular inspection to ensure seals, coils, and enclosures remain intact, but maintenance schedules depend on the environment and usage.

Yes, but it’s generally more cost-effective to use a standard solenoid valve in safe zones unless you need uniformity across all installations.

Check for ATEX markings on the product label (e.g., II 2G Ex d IIC T6) and ensure the documentation includes certification details.

Yes, they are available in both AC and DC voltage options, but you must match the coil voltage to your system specifications.
