Solenoid valves, 488 Series
These are 2 stage valves actuated electro-pneumatically. A serie 300 directly operated solenoid valve actuates pneumatically the principal power distributor.
Solenoid valves 3/2, 5/2, 5/3
These are 2 stage valves actuated electro-pneumatically. A sérié 300 directly operated solenoid valve actuates pneumatically the principal power distributor. This integrated System allows configurations of Systems requiring very little space. The pilot air is normally taken from the inlet port (autofeed) and the only actuating signal is electric.
The range of the solenoid valves, as far as dimensions and mechanical construction, is similar to sériés 200. We hâve therefore solenoid valves G 1/8", G 1/4", G 1/2" and G 1" with identical pneumatic characteristics that are, however, actuated electrically. They hâve a balanced spool, insentive to presence or absence of pressure. They are constructed in 3 and 5 way with 1 solenoid (monostable) or 2 solenoids (bistable) and also 5 ways 3 positions with closed centres, open centres and pressured centres.
If should be noted that the autofeed of the electric pilot requires always inlet through port 1 and if a 3 ways normally open configuration is desired, it is necessary to switch the operators.
In the tables showing individual valves, the quick reference tables show the output in Nl/min at a inlet pressure of 6 bar and a pressure drop of 1 bar. AN information was obtained using standards CETOP RP 50R
Solenoid valves G118" and G1 /4" can be equipped with microsolenoids as well as standard solenoids and they can be mounted in line or in 90 degrees on distributors.
