AIR DISTRIBUTION General Solenoid valves Series 514/N "NAMUR" These are 2 stage valves actuated electro-pneumatically. A serie 300 directly operated solenoid valve actuates pneumatically the principal power distributor. Everything is well integrated in a practical configuration that also permits applications where there is limited space. Used primarily to operate rotary actuators and wherever there is a “ NAMUR” standard installation plan. The pilot air is normally taken from the inlet port (autofeed) and the only actuating signal is electric. The range of the solenoid valves, as far as dimensions and mechanical construction, is similar to series 200. We have therefore solenoid valves G 1/4" with identical pneumatic characteristics that are, however, actuated electrically. They have a balanced spo- ol, insentive to presence or absence of pressure. They are constructed in 3 and 5 way with 1 solenoid (monostable) or 2 solenoids (bistable). Construction characteristic Use and maintenance These valves have an average life of 15 million cycles depending on the application and air quality, filtered and lubricated air using specified lubricants will dramatically reduce the wear of the seals and ensures long and trouble free operation. Please ensure that the valve is being used according with the manufacturers specification, such as air pressure and temperature and that exhaust ports 3 & 5 are protected against the possible ingress of dirt or debris. Repair kits including the spool complete with seals are available for overhauling the valves; however, although this is a simple operation it should be carried out by a competent person. ATTENTION: use hydraulic oil class H for lubrication such as MAGNA GC 32 (Castrol). “ NAMUR” interface dimensions: according to standard (VDI/VDE 3847 July 2003) Body Aluminium Operators Aluminium Spools Nickel plated steel Seals NBR Spacers Technopolymer Springs Spring steel Screw Zinc coated Steel
