Technical information
Index for identification of the type/series of valve required Table for selecting solenoid valves based on fitting size, porting, function
The horizontal rows indicate the porting and the function of the solenoid valve seriesrequired. The vertical columns indicate the size of the fittings for the series of solenoid valves included in the table. The codes in the table identify the series (one or more) of valves with the required features in addition to the colour background as indicated on the right-hand page for their use.

Once the series required has been identified: 1: look up on pg. 3 the catalogue page corresponding to the series of solenoid valves; 2: go to the contents page of the section corresponding to the type of application (the second in the section): the section is indicated by the background colour of the box where the required series isidentified. In this section you will find all the specific technical information on the double page of the series required.
