How to select the proper valve?
Although the construction of solenoid valves is relatively simple, selecting them for a given type of installation or application should take into account several important issues that have a large impact on the proper and correct selection of the valve.
While the selection of valves for typical applications is not difficult, many problems can be caused by selecting a valve to work in unusual applications. This applies in particular to intermediate-acting valves, where the selection of the valve on the basis of the diameter of the pipeline only is unacceptable.

Undesirable effects associated with incorrect valve selection appear both in its under-dimensioning and over-dimensioning.
Underdimensioning is likely to cause:
- inability of reaching the desired flow
- incidence of liquid conversion into steam at the valve’s outlet
- drop of outlet pressure
- undesirable pressure loss in installation
Overdimensioning is likely to cause:
- unnecessary costs increase due to purchasing overdimensioned equipment
- inconsistent flow through the valve or incorrect flow control
- shortening of some valves lifetime as a result of internal parts vibration, caused by the lack of proper flow and formed to generate internal differential pressure
- erosion of seal in some constructions caused by valve operation in almost closed position
