ASCO EFG551H402MO 3/2 NC - 5/2 Solenoid air pilot operated and return bistable Solenoid valve

FEATURES
1. 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 integrity levels: SIL

2 for HFT = 0 / SIL 3 for HFT = 1
2. The spool valves have threaded port connections and "NAMUR" style interface
3. 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
4. The same spool valve can be adapted for 3/2 NC or 5/2 function for controlling double-acting and single-acting actuators
5. The valve offers environmental protection against the ingress of liquids, dusts or any other foreign matter (environmentally-protected construction)
6. Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
7. The solenoid valves satisfy all relevant EU Directives
