SCG551A001MS ASCO 3/2 ways 1/4 inch solenoid valve

FEATURES

1. The monostable spool valves have TüV-EXIDA certified IEC 61508 Functional Safety data and can be used up to SIL 4 (551/TüV)-SIL 3 (552-553/EXIDA)

2. The spool valves have threaded port connections and "NAMUR" style interface

3. The same spool valve can be adapted for 3/2 NC or 512 function for controllingdouble- acting and single-acting actuators

4. All the exhaust ports of this spool valve are connectable, providing better environmental protection, particularly recommended for sensitive areas such asclean rooms, and applications in the pharmaceutical and food processing sectors

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

6. Epoxy moulded coil for general service applications

7. The solenoid valves satisfy all relevant EC Directives
