Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Spool valves and solenoid valves Series 200 1 Air distribution 1 | 21 Series 200 General The series 200 consist of a broad range of valves with various type of actuation. The connections for this series are from G 1/8" to G 1". Due to their special construction with a balanced spool, these valves can be used interchangeably as 3 ways or 5 ways. The 3 ways can be used normally closed or normally open and the 5 ways can be fed through the exhausts 3 and 5 with different pressures according to the need. The spool, as it is moving, isolates the connections without being affected by the inlet pressure. Construction characteristics G 1/8" - G 1/4" - G 1/2" - G 1" Body Aluminium Operators Aluminium Technopolymer Seals NBR PUR for 212/2 Spacer Technopolymer Aluminium for G1" (211) Spools Steel Aluminium, for 212/2 Springs Spring steel Pistons Technopolymer, for 228 pneumatic command valves Aluminium, for 224, 212, 212/2 e 211 pneumatic command valves 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).
