Working Principle Of Dead Leg Valve

The diaphragm in the gemu zero dead leg valve will act as a switch, in addition to a sealing element for the media. The diaphragm is easily replaceable and along with its handle mechanism is protected by a bonnet. To adjust the flow, the handle can be positioned to the right degree, according to the indicator, that is positioned above itself. A special feature of the zero dead leg valves is their inlet ports, which permit continuous flow of the media in a loop. This design has ensured the virtual elimination of dead legs at the inlet port. So when the valve is opened, it is possible to receive clear uncontaminated media that remains free from bacterial growth. The outlet of the dead leg valve also acts as a drain port while the device is undergoing sterilization.
