A S E R I E S Catalogue 001 Directly operated solenoid valves Series A / way, 3/ way monostable, stable (with magnetic memory) Ports M5, G1/8, cartridge ø 4 The Series A solenoid valves are of the directly operated type and can be used with dry or lubricated air. They are available in the / and 3/-way versions with normally closed (N.C.) or normally open (N.O.) operations. They are also supplied in versions which differ with respect to the type body, the threaded ports and the orifices, as indicated in the tables for each type, in order to satisfy various operating and installation requirements. Mechanically, they have been very carefully designed: the internal parts are made of stainless steel and the seals are of NBR. The electromagnet (or solenoid) is separate and can be easily and rapidly replaced without interfering with the pressurised part of the valve. This series of solenoid valves has 3 different types of solenoids which can be interchanged on the same mechanical part. The choice of solenoid determines the performance of the solenoid valve (consumption and pressure).

Catalogue 001 S E R I E S A Solenoids for Series "A" solenoid valves The solenoids for Series A solenoid valves, models A70 and A80, are of the monostable type (see connection diagram in Fig. 1). The dimensions as well as the power consumption of these solenoids differ so that the best possible choice can be made depending on the type of electronic or electromechanical operating system used. The model G90 is a special type of solenoid for pulsed operation. A short pulse, with a maximum duration of 0 ms, causes the poppet to be engaged; another short pulse on the secondary circuit causes it to be released. Repeated pulses on the same circuit do not change the position of the poppet. This feature allows a Series "A" solenoid valve to be converted from an monostable type to a stable type, without modifying any mechanical parts.

Catalogue 001 S E R I E S A Solenoid G90 G90 solenoid valves (coils) can be replaced on all other Series A solenoid valves or pilots ( x ) allowing to change the valve functioning from: - monostable functioning system (spring return) closed circuit = attracted magnetic = opened poppet if NC, closed if NO. opened circuit = released magnetic = closed poppet if NC, opened if NO. - to stable functioning system (memory) impulse on A circuit = attracted magnetic (latched) impulse on B circuit = released magnetic (unlatched) the stable functioning has the following advantages: - the solenoid valve consumption is practically none as the open and close control occurs thanks to an impulse of about 0 m/s after which the valve always remains in the controlled position, without any feeding until the inverse impulse which changes the position is sent. - the valve remains in the controlled position (opened or closed) even when the electrical feeding of the installation where the valve is inserted is missing, allowing the valve to be used as a position memory. - when normally opened valves should be used, it is not necessary to use valves with special (reverse) mechanical parts as a NC valve becomes a NO valve just by changing the control impulse sequence. - The impulse control system facilitates the utilization with electronic circuits. The minimum required impulse for the function is 0 ms; if, for circuit reasons, the impulse last for a longer period, there is no danger of heating as the solenoid has been designed to work also with 100% ED. General operating data. The control of G90 solenoid valves is effected by impulses: - magnetic attraction control = latched (A) - magnetic release control = unlatched (B) Assuming a normally closed valve, the situation is: - Unlatched = open valve - Latched = closed valve During the control sequence, one has to wait for at least 10 ms between a latch control and a unlatch control on the same valve (see Fig. 1). When the G90 solenoid valves are assembled on a manifold between each others, or with normal type valves, a G90/L magnetic shield has to be used in order to avoid magnetic interferences. The solenoid valve has three terminals numbered 1,, 3 and the electrical connections for the exchange are indicated in the following. Control circuits: - For alternating current (fig. ) tables. The control is effected through closing contacts on terminals 1 and, whereas terminal 3 is steadily connected to a phase. Caution: do not invert terminal 3 with terminals 1 and as this could cause a short circuit. When controls with PLC are used, keep in mind that the coil is bi-functional, terminal 3 should be connected to the neutral wire whereas terminal 1 should be connected at the end of the unlatch control, and terminal at the end of the latch control. - For direct current (fig. 3). The control is effected through two switching contacts which reverse the sense of the current to the coil through terminals 1 and (terminal 3 is not used). In order to simplify the control system, an electronic interface can be used. This electronic interface is made up of a normal connector with a circuit which effected the current inversion to the spool thanks to a single control and two contacts, as for alternate current type. The interface is necessary for the PLC control in direct current. Fig. 4 indicates the valve connection to the PLC in direct current.
