SCHTG551B402MO 1/4inch Solenoid valve air pilot operated and return (bistable)
FEATURES
• The monostable spool valves in conformity with IEC 61508 Standard (2010
route 2 H 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 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 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)
• 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
