Product Description
EF551B401MO EF8551B401MO single coil EF551B402MO double coil
Solenoid valve pilot operated, spool type G1/4"Threaded Explosion proof single coil
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

temperature range (TS) -25°C to +60°C
INSTALLATION
• Multi language installation/maintenance instructions are included with each valve
• The solenoid valves can be mounted in any position without affecting operation
• 3/2 NC-5/2 spool valve supplied with one or two interface plates with NAMUR mating surfaces. Depending on function (3/2 NC or 5/2), position the plate (series 551) or one of the two plates (series 553) on the spool valve body before installing on actuator
• Do not connect the pressure supply to the exhaust port 3. The “environmentally-protected” construction is not adapted for NO function. Contact us for function available in specific version
• Dowel pin (if necessary), bolts and gaskets are standard supplied
• IEC 61508 Functional Safety (suffix SL). Check temperature range of valve body and solenoid for suitability. For probability of failure, contact us
• It is necessary to connect pipes or fittings to the exhaust ports to protect the internal parts of the spool valve and its pneumatic operator if used outside or in harsh environments (dusts, liquids etc.)
• Threaded pipe connection identifier is 8 = NPT (ANSI 1.20.3); G = G (ISO 228/1)
• Ex db Prefix "NF/WSNF" enclosure is provided with a 1/2" NPT threaded entry hole, M20 x 1,5 (prefix "ET") is optional. These are supplied without cable gland
• To comply with IEC 61508 (SIL) the valves must be provided with a specific exhaust protector (see following pages)
• The solenoid valves can be mounted in any position without affecting operation
• 3/2 NC-5/2 spool valve supplied with one or two interface plates with NAMUR mating surfaces. Depending on function (3/2 NC or 5/2), position the plate (series 551) or one of the two plates (series 553) on the spool valve body before installing on actuator
