solenoid valves 3/2 nc 5/2 3/2 pilot operated, spool type ... asset library/solenoid...

All leaflets are available on: www.asco.com

PIC-6-45-GB

FEATURES• The monostable spool valves in conformity with IEC 61508 Standard (2010

route 2H version) have TÜV (551 series) and EXIDA (551-553 series) certified with integraty levels: SIL 2 for HFT = 0 / SIL 3 for HFT = 1

• The solenoid operated spool valves have threaded port connections and "NAMUR" interface

• The same spool valve can be adapted for 3/2 NC or 5/2 functions for controlling double-acting and single-acting actuators

• All the exhaust ports of this spool valve are connectable, providing better environmental 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 EU Directives
