1 Series 200 - Mechanical and manual command 1.20 Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice. General The series 200 consist of a broad range of valves with various type of actuation. The connections for this series are fromG 1/8" toG 1". Due to their special construction with a balanced spool, these valves can be used interchangeably as 3 ways or 5 ways as can be seen in the functional schematics in section 0. This is important because, for example, 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 ismoving, isolates the connections without being effected by the inlet pressure. The main components constituting the valves of the Tecno228 series are manufactured with high performance technopolymer. The use of technopolymer has resulted in a light weight product which can be offered to the market at very interesting prices. This valve series is manufactured with 1/8” connections, 3 and 5 ways function, mechanical or pneumatically operated, monostable spring or pneumatic return, bistable and in 5 ways 3 positions version with closed, open and pressured centres. This series is completely interchangable with the standard 228 series (with alluminiumbody).

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 asMAGNAGC 32 (Castrol).
