Specifying the correct solenoid valve for your application
The type of solenoid valve most appropriate for each application is governed by a number of factors. Many of the solenoid valve components, such as the plunger, return spring and seals are all exposed to the media and therefore information on the chemical compounds, temperature and pressure are all necessary to make an informed material selection.
Which type of Solenoid Valve design?
In the case of solenoid valve design, the general rule-of-thumb is: Plunger-type direct acting solenoid valves are best suited to neutral and clean fluids, while pivoted armature solenoid valves employ a media-separating membrane and are therefore suitable for controlling corrosive, contaminated or aggressive fluids.
If the production process involves liquid food products, the plastics and elastomers used should also conform to the local food and hygiene regulations. In addition, some processes require a cleaning cycle to be performed in between production processes and so the data is also required for this procedure as well to ensure there is no undue material degradation caused by steam or cleansing chemicals.
