ASCO Numatics Ex ia intrinsically safe solenoid operated pilot is suitable for all hazardous areas

ASCO Numatics has introduced an intrinsically safe (Ex ia) solenoid operated pilot that is suitable for all hazardous areas, regardless of the gas zone and temperature class. The LISC solenoid operator is compatible with ASCO Numatics spool valves and has a low power consumption. Rated to IP67 it is approved for use in dusty atmospheres.

Ex ia protection enables the valve to be installed in explosive atmospheres up to zone 0-20. This makes it ideally suited to applications in the chemical, oil and pharmaceutical industries, or in processing and packaging plants for flammable products.

Compatible with all intrinsic safety isolated zener barriers, the solenoid features an aluminium body with an FPM seal and has a power rating of 0.46W at 12/24V DC. The pilot has a pressure rating of 2 to 10 bar and can be used in temperatures from -40°C to +65°C. The device is certified to IECEx/ATEX II 1G Ex ia IIC T6 Ga and II 2D Ex ib IIIC T85°C Db IP67.
