Specifications:
The document outlines the classification and specifications of ATEX valves and solenoids, which are designed for use in potentially explosive atmospheres. The classifications include II 2GD and II 3GD, with temperature classes ranging from T4 (135°C) to T6 (85°C). The equipment is suitable for non-mining areas and complies with the ATEX directive 94/9/EC.

Procedures:
The document specifies that the class of an assembled system is determined by the lowest classified component. It also details the types of atmospheres (gas and dust) and their presence, which dictate the category of devices required.

Standards and Norms:
The valves meet the ATEX directive 94/9/EC, ensuring safety in explosive atmospheres by preventing mechanical sparks, electrostatic charges, and surface heating. The document also mentions compliance with IP65 protection standards.

Technical Features:
The ATEX valves feature an aluminium body with alodine surface treatment, NBR seals, and brass spacers. They operate within a medium temperature range of 0°C to 25°C and an environment temperature range of -5°C to 50°C. The valves use filtered air and do not require lubrication.

Recommendations:
It is recommended to use only EPC coils on Vesta ATEX solenoid valves. The document advises consulting the corresponding non-ATEX valves for technical features and visiting the Vesta website for use instructions.

Key Components:
The document lists various valve series and their codes, including pneumatic and solenoid valves, with specific temperature and pressure ratings. It also provides details on explosion-proof coils, including standard voltages and power specifications.
