ASCO 302 Series | Ex ia Intrinsically Safe ATEX IECEx Mini-Solenoid Valves 3/2 NC

eX ia intrinsically safe mini-SOLENOID VALVES

ASCO 302 series

ASCO 302 series are direct operated and pad mounted explosion proof solenoid valves which are ATEX certified for installation in potentially explosive atmospheres located in hazardous areas.

The low consumption mini solenoid valves with Intrinsically Safe IEC explosion protection techniques, are suitable for use in hazardous areas with exposure to gas, classified as Zone 0 or those exposed to dust and classified as Zone 20.

They can also be used in the chemical, oil and pharmaceutical industries, or in processing and packaging plants for flammable products such as solvents or paints.

Hazardous Area Classification & Ex Safety Code

ATEX Solenoid Valves

Ex II 1 G Ex ia IIC T6 to T4 Ga
Ex II 1 D Ex ia IIIC T 85°C to T135°C Da

Electrical enclosure protection: Moulded IP65 (EN 60529).

EC type certificate INERIS 03 ATEX 0249X and IECEx certificate IECEx INE 10.0002X.

The intrinsically safe mini solenoid valves are compliant with International and European Standards IEC and EN: 60079-0, 60079-11 and 60079-26.

TEMPERATURE CLASSIFICATION TABLES

DC (=)

Minimum ambient temperature: 0°C (0,25 W) / -10°C (0,5W)

The coil is designed for permanent duty within maximum ambient temperature limits. The solenoid valve must be connected to a special certified electrical supply unit installed in a non-dangerous zone.
