Spool valves and solenoid valves Series 400 Series 400 General Air distributiOn 1 these are 2 stage valves actuated electro-pneumatically. A serie 300 directly operated solenoid valve actuates pneumatically the principal power distributor. this integrated system allows configurations of systems requiring very little space. 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 1/8", G 1/4", G 1/2" and G 1" with identical pneumatic characteristics that are, however, actuated electrically. they have a balanced spool, insentive to presence or absence of pressure. they are constructed in 3 and 5 way with 1 solenoid (monostable) or 2 solenoids (bistable) and also 5 ways 3 positions with closed centres, open centres and pressured centres. if should be noted that the autofeed of the electric pilot requires always inlet through port 1 and if a 3 ways normally open configuration is desired, it is necessary to switch the operators. Solenoid valves G 1/8" and G 1/4" can be equipped with microsolenoids as well as standard solenoids and they can be mounted in line or in 90 degrees on valves. Please note that while the microsolenoid can be mounted in any direction, standard solenoid requires mounting as inticated in the photographs and diagrams. The order codes pertain only to the solenoid valve with mechanical actuator "M2" or solenoid "S*" already assembled. M2 coils are not included and have to be ordered separately (see Series 300). Coils for M2 and solenoids "S" homologated are available (see Series 300). Construction characteristics body Aluminium Operators Aluminium Technopolymer for spring botton plate G 1/8", G1/4", G 1/2" and aluminium for G 1" nbr Polyurethane compound for oil free applications (G 1/8", G 1/4" and G 1/2") Technopolymer (aluminium for G1") steel stainless steel or spring steel seals spacer spools springs Use and maintenance this valves have an average life of 15 million cycles depending on the application and air quality. Filtered and lubricated air using specified lubricants will 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. the exhaust port of the distributor has to be protected in a dusty and dirty environment. 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). 1 | 90 Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice
