Solenoid/Spool Valves Intrinsically Safe Solenoid Pilot for Hazardous Areas
Asco Numatics has introduced an intrinsically safe (Ex ia) solenoid operated pilot that is suitable for operations in 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. Its intrisically safe construction makes it possible to install the valve even in explosive atmospheres up to zone 0-20. With these features, the unit is well suited for applications in the chemical, oil and pharmaceutical industries, or in processing and packaging plants for flammable products, the manufacturer states.
The solenoid is compatible with all intrinsic safety isolated zener barriers, featuring an aluminium body with an FPM seal and 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.
