How to choose a solenoid valve
While searching for the perfect solenoid valve for your situation, you should ask a few questions of yourself.
- Which sealing material is resistant to my medium?
- Which housing material is best suited for the medium and pressure?
- How large should the valve passage be?
Answering such questions can sometimes be difficult without the necessary knowledge. Therefore, this newsletter takes you through the process of selecting a solenoid valve. After reading and watching the videos, you will have enough knowledge to confidently choose the most suitable model!
The starting point of our search is the following video, which gives an overview of the different types of solenoid valves on the market:

Sealing material
Solenoid valves are often available with different sealing materials. Typical sealing materials are NBR, EPDM, FKM (Viton) and PTFE (Teflon). The choice of material is very much dependent on the chemical properties, pressure and temperature of the medium to be controlled by the solenoid valve. The right choice is crucial to ensure a long life and optimal performance of the valve.

Housing material
In addition to sealing materials, solenoid valves are also available with various housing materials. Frequently used materials are nylon (polyamide - PA), PVC (polyvinyl chloride), brass, nickel-plated brass and stainless steel - stainless steel (304 or 316). Which material you need is again dependent on the chemical properties and temperature of the medium to be controlled by the solenoid valve.

Calculate Kv value
The Kv value is an indication of the volume flow through a valve for a given medium and pressure drop. The larger this value is, the higher the volume flow through the valve at a given pressure drop is. Generally, the Kv value is given in the product description or technical data sheet. It is a better reference than, for example, the size of the pipe connection or the diameter of the orifice. The Kv value is measured as the volume flow of water in m3/h with a pressure drop of 1 bar at 20°C.
If the properties of the medium , the pressure drop and the desired volume flow are known, the required Kv value of the valve can be calculated. There are different formulas for liquids and gases.
