ASCO 195/LISC Series | Ex ia Intrinsically Safe ATEX IECEx Solenoid Valves 3/2

Product Overview

ASCO 195/LISC series

ASCO 195/LISC 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 solenoid valves with Intrinsically SafeIEC explosion protection techniques, are suitable for use in hazardous areas with exposure to gas, classified as Zone 1. They can be used in the chemical, oil and pharmaceutical industries, or in processing and packaging plants for flammable products such as solvents or paints.

This compact, intrinsically safe, monobloc pilot solenoid valve with a spade plug connection (ISO 4400/EN 175301-803) can be mounted as operator onto valve 551-553 series.

They are SIL3 capable with EXIDA approval.
