Working Principle of Diaphragm Valves
The basic operating principle of diaphragm valves is the use of a flexible diaphragm. This diaphragm flexes under the pressure of the fluid and opens or closes the holes in the valve body. It usually consists of a diaphragm built into a valve body and a control mechanism mounted on top. Pressure changes regulate flow by controlling the movement of the diaphragm.
In diaphragm valves, the so-called “Pilot system”; able to work with little power; There is a mechanism that directs a small amount of water flowing through it and directs some water to the upper part of the diaphragm or to the outlet. This system, which can operate even with a small current produced by the battery, is possible to open and close the valve by controlling the pilot system with the help of an electronic circuit. For this reason, diaphragm valves seem to be almost the only solution in places where it is desired to start or cut off the flow of water with a remote control.
Another usage area is places where it is desired to provide or prevent flow by preventing chemicals with high destructive properties from damaging the valve (such as chemistry laboratories). The diaphragm between the valve mechanism and the fluid (It is manufactured from different materials that are not affected by chemicals, such as natural rubber, PTFE, Viton, Hypalon, with original formulas.). Since it prevents the contact of the mechanism with the fluid, the valve can open and close for a long time.
