The Series A solenoid valves are of thedirectly operated type and can be used withdry or lubricated air.They are available in the 2/2 and 3/2-wayversions with normally closed (N.C.)or normally open (N.O.) operations.They are also supplied in versions whichdiffer with respect to the type body,the threaded ports and the orifices, asindicated in the tables for each type, in orderto satisfy various operating and installationrequirements. Mechanically, they have beenvery carefully designed: the internal partsare made of stainless steel and the seals areof NBR. The electromagnet (or solenoid)is separate and can be easily and rapidlyreplaced without interfering with the pressurised part of the valve.This series of solenoid valves has 3 differenttypes of solenoids which can be interchangedon the same mechanical part. The choice ofsolenoid determines the performance of thesolenoid valve (consumption and pressure).

Solenoids for Series "A" solenoid valves

The solenoids for Series A solenoid valves, models A70and A80, are of the monostable type (see connection diagram in Fig. 1). The dimensions as well as the powerconsumption of these solenoids differ so that the best possible choice can be made depending on the type ofelectronic or electromechanical operating system used.The model G90 is a special type of solenoid for pulsedoperation. A short pulse, with a maximum duration of 20ms, causes the poppet to be engaged; another short pulseon the secondary circuit causes it to be released.Repeated pulses on the same circuit do not change theposition of the poppet. This feature allows a Series "A"solenoid valve to be converted from an monostable typeto a stable type, without modifying any mechanical parts.

Mod. G90 solenoid valves (coils) can be replaced on all other Series A solenoid valves or pilots(22 x 22) 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 20 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 electricalfeeding 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 20 ms; if, for circuit reasons, the impulse last for a longerperiod, 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 aunlatch control on the same valve (see Fig. 1). When the G90 solenoid valves are assembledon a manifold between each others, or with normal type valves, a G90/L magnetic shield hasto be used in order to avoid magnetic interferences. The solenoid valve has three terminalsnumbered 1, 2, 3 and the electrical connections for the exchange are indicated in the following.Control circuits:- For alternating current (fig. 2) tables. The control is effected through closing contacts

on terminals 1 and 2, whereas terminal 3 is steadily connected to a phase.Caution: do not invert terminal 3 with terminals 1 and 2 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 2 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 2 (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 valveconnection to the PLC in direct current. With special electronic connector of 122-892P type with positive wire and 122-893N with negative wire.
