Namur valves, pilot operated or air operated, spool type single/dual solenoid or air (mono/bistable function) aluminium body, 1/4 bsp to 1/2 bsp ports
ASCO direct mount air solenoid valves utilize the standard NAMUR interface mounting pattern. NAMUR provides a standard footprint for mounting directional control valves directly to a pneumatic rotary actuator, eliminating unnecessary pipe or tubing. The valve is convertible from a 4-way 2-position to a 3-way 2-position valve for operating either double acting or spring return actuators. The compact high flow design includes a black anodized aluminium body, low wattage epoxy moulded coil with DIN style plug connector (included), unique spool design with NBR/polyurethane seals, and a manual override. Optional speed control mufflers can be screwed into the exhaust ports for controlling the speed of an actuator (order separate). Many customers select these valves as an option for use with our air actuated ball valves.
FEATURES
• The monostable spool valves, series 551, have TÜV certified IEC 61508 Functional Safety data and can be used up to SIL 4/AK 7
• The spool valves have threaded port connections and "NAMUR" style interface
• The same spool valve can be adapted for 3/2 NC or 5/2 function for controlling double-acting and single-acting actuators
• 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
• The valve offers environmental protection against the ingress of liquids, dusts or any other foreign matter (environmentally-protected construction)
• Epoxy moulded coil for general service applications
• The solenoid valves satisfy all relevant EC Directives
