Explosion-proof ATEX electrohydraulic systems: essential for safety and efficiency in the Oil & Gas sector

Explosion-proof electrohydraulic systems are widely used in the Oil & Gas industry. The most significant applications include:

Drill heads
Offshore platform lifting
Anchoring systems hydraulic arms for handling drilling pipes

These installations require advanced control capabilities, high reliability, and full compliance with stringent international standards such as ATEX, IECEx, and UL.
They must also meet the strictest safety requirements and guarantee the highest Safety Integrity Level (SIL3) according to IEC 61508.
As a result, ATEX Electrohydraulic Systems are the most reliable solution for delivering advanced safety, consistent performance, and environmental compliance in the Oil & Gas applications, thanks to their high customizability and a wide, diversified range of available certifications.

Electrohydraulic systems for Oil & Gas applications

Explosion-proof electrohydraulic systems are fundamental for ensuring the safety and efficiency of offshore platform lifting and anchoring operations.
These systems are engineered to withstand extreme environmental conditions, including saltwater corrosion and potentially explosive atmospheres due to the presence of oil and gas.
Explosion-proof electrohydraulics also allow precise control of drilling arm operations, ensuring safety and efficiency throughout all process stages. These systems feature explosion-proof proportional valves that enable fine motion control, crucial for preventing accidents and equipment damage.
Explosion-proof hydraulic systems are designed to perform reliably under these harsh conditions, providing maximum durability and operational integrity.
Each actuation circuit incorporates explosion-proof solenoid valves selected according to the level of control required by the specific operation.

Stainless steel power unit

On/off valves are typically employed for service functions or movements with limited dynamic demands, while proportional valves equipped with integrated electronics and internal feedback are used whenever higher precision and faster response are necessary, ensuring superior performance even in the most demanding applications.
To ensure high corrosion resistance, hydraulic manifolds, valves, and actuators are treated with dedicated offshore C5X coating cycles, featuring thicknesses of up to 300 μm to provide effective protection against aggressive marine environments. Piping and fittings are generally manufactured from stainless steel, which offers strong resistance to oxidation and long-term durability.
Furthermore, in installations exposed to particularly harsh weather or extremely low temperatures, it is common practice to adopt explosion-proof valves made entirely of stainless steel, as they maintain consistent performance and durability even under the most demanding environmental conditions.

Atos: the most comprehensive range of explosion-proof hydraulic components and systems

The classification of potentially explosive areas may vary depending on the type of installation and the specific location within the plant. In the case of loading arms, the operating zone is typically classified as Zone 1, which requires the use of Ex-d explosion-proof valves combined with Ex-h certified actuators and pumps.
This configuration helps prevent risks associated with both the presence of hot surfaces and with moving mechanical components, ensuring safe operating conditions.
Atos offers a broad selection of explosion-proof electrohydraulic components with international certifications, designed for use in hazardous areas and available in configurations ranging from on/off assemblies to fully integrated system solutions.

Explosion-proof proportional valves equipped with integrated digital electronics make it possible to bring advanced industrial automation capabilities into hazardous areas. This technology enables the use of nextgeneration communication protocols, supports diagnostic tools such as built-in oscilloscopes, and allows the management of high-performance axes, including pQ control functions, ensuring extreme accuracy and reliability in demanding operations.
In addition to proportional solutions, the range also includes on/off versions engineered to meet more stringent safety requirements in equipment operating within potentially explosive areas. These variants comprise explosion-proof solenoid valves compliant with Safety Integrity Level SIL2 and SIL3, as defined by IEC 61508.

Ex-proof proportional cartridge

The offer further includes directional valves equipped with inductive proximity sensors, which continuously detect the spool position to ensure accurate monitoring of the valve’s operating status.
Explosion-proof hydraulic power units (HPUs) and manifolds designed for Oil & Gas applications are available with certifications issued by leading international bodies such as TÜV, DEKRA, UL, CSA, ABS, BV, DNV GL, and RINA.
These systems are manufactured according to strict construction criteria, with particular attention to material quality and full compliance with customer specifications. Dedicated offshore coating cycles further enhance long-term resistance and reliability, making the Atos Systems Division a trusted partner for installations operating in highly demanding environments.
