Typical design of diaphragm-separated solenoid valves

The diaphragm solenoid valves are divided into two parts: the valve, which closes the flow path and the drive that operates the valve parts. A membrane inside the valve separates the two parts from each other, so that the medium is only in contact with the valve body and the separating membrane and not with the drive parts. Due to the design of the diaphragm, the potential for corrosion of the cylinder or other drive parts is prevented. The potential for contamination of the medium, due to detachable substances such as dust or metal from wear and tear during longer operating times, is prevented too. The use of chemically resistant materials such as PTFE, PEEK and FFKM enables high chemical inertness. Because of the design, this type of valve is especially suitable for analytical or medical devices.
