FEATURES
• All the exhaust ports of the 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 valves offer environmental protection against the ingress of liquids, dusts or
other foreign matter (environmentally-protected construction)
• 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
• The solenoid valves satisfy all relevant EU directives
