5 3 way ss valve

All leaflets are available on: www.asco-process-scope.com

PIC-5-35-GB

FEATURES The monostable spool valves have TV-EXIDA certified IEC 61508 Functional

Safety data and can be used up to SIL 4 (551/TV)-SIL 3 (553/EXIDA) The 5/2 and 5/3 solenoid operated spool valves have threaded port connections All the exhaust ports of this spool valve are connectable, providing better environ-

mental protection, particularly recommended for sensitive areas such as clean rooms, and applications in the pharmaceutical and food processing sectors

The valve offers environmental protection against the ingress of liquids, dusts or any other foreign matter (environmentally-protected construction)

Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket

The solenoid valves satisfy all relevant EC Directives

FEATURES The monostable spool valves have TV-EXIDA certified IEC 61508 Functional

Safety data and can be used up to SIL 4 (551/TV)-SIL 3 (553/EXIDA) Series 551 versions according to ATEX 94/9/EC, for zones 0, 1 and 2 and series

553 air-operated versions for zones 1 and 2 The 3/2 NC solenoid operated spool valves have threaded port connections All the exhaust ports of this spool valve are connectable, providing better environ-

mental protection, particularly recommended for sensitive areas such as clean rooms, and applications in the pharmaceutical and food processing sectors

The valve offers environmental protection against the ingress of liquids, dusts or any other foreign matter (environmentally-protected construction)

The solenoid valves satisfy all relevant EC Directives
