GENERAL APPLICATION VALVES 3/2 - DIRECT OPERATED
`
DIMENSIONS
Solenoid valves are electro-mechanical devices that control fluid flow. This is
achieved by opening or closing one or several orifices in the solenoid valve. The
(solenoid) coil is the electrical element that converts an electrical signal into a
mechanical force which, in turn, shifts the mobile plunger that opens or closes
an orifice (nozzle) by means of its seat disc(s). Solenoid valves are usually
constructed from 3 distinct components:
•
The body (including the sleeve assembly)
•
The coil (or coil housing)
•
The housing (or nut/nameplate fixing elements).
These 3 modular components are in many cases interchangeable i.e. a valve
body can be used with a number of coil/housing combinations.

DIRECT OPERATED VALVES (SEE FIG. 1)
The magnetic force is used directly to open or close the passage of fluid at the plunger sealing. The performance is limited
by the available performance of the coil (limits of pressure/orifice size.)The pressure rating of the valve starts from zero bar
to the maximum value.
