The main feature of this version is the high-resistance thermoplastic material from which the components are moulded. This made it possible to obtain an aesthetically pleasing product with a considerably reduced weight compared to the standard version, and, most importantly, a reduction in price. There are also changes of a technical and functional nature, however, startingwith the use of a rolling diaphragm in place of the traditional piston, thus eliminating friction andwear on the seal. For versions with microsolenoid and internal or external supply, there is a fast discharge system incorporated in the operator, which reduces the response time for repositioning the valve by 60%.Themechanisms of the actuation solenoid valve are theMP with external supply and MV for self-supplied versions (they differ from the M2 and M2/V, used on zamak valves, for self-tapping fixation screws in plastic). There are also double versions either for air or for vacuum on which, in place of the standard actuation mechanisms, there is a solenoid valve 3/2 Solenoid-Solenoid complete with 15mm24VDCmicroactuators (code N331.0A). The ordering codes correspond to the solenoid valves with mechanisms that are "MP" or "MV" mounted. The windings are not included and have to be ordered separately (see summary page for electric windings) with the exception of the dual versions which already have windings 24V DC (N331.0A). Certifiedwindings are also available Body, operator and bottom Seals and shutters Piston and guide pin Springs Diaphragm High resistance thermoplastic material Nitrile rubber (NBR), oilproof Acetal resin Stainless steel AISI 302 Rubberised fabric in nitrile (NBR) compound, oilproof Wear and maintenance These valves and solenoid valves have an average service life of approximately 10 - 15 million cycles under optimum conditions of usage. They do not need to be lubricated to operate well, but good filtration is recommended to prevent dirt accumulation inside. Ensure that the conditions of use are consistent with the indicated limits, pressure, temperature, etc. Take care to protect the discharge outlets of the valves in the presence of dirt and powder. For these products, due to the manner in which they are constructed and the particular use for which they are intended, maintenance by replacing valve parts does not have to be carried out. When necessary, basic internal cleaning can be performed, carefully removing any dirt accumulations. When the self-supply version is used in the solenoid valves, take care that the use is never, as air flow, the same as the supply, because in this case there would not be sufficient vacuum for actuation. This is normally found on shutter valves since they do not have the closed centres position and insufficient actuation could cause the system to discharge fromoutlet 3.In this case switch to the version with external actuation.
