Cast Iron Diaphragm Valve
Introduction:
Diaphragm valve is in the valve body and the valve cover is equipped with a flexible diaphragm or combined diaphragm, the closing part is connected with the diaphragm of a compression device. The seat can be weir shape, or can be through the flow channel wall.
Features:
The advantage of diaphragm valve is that its control mechanism is separated from the medium path, which not only ensures the purity of the working medium, but also prevents the possibility of medium impact on the working parts of the control mechanism in the pipeline. In addition, a separate seal of any kind at the stem is not required except for use as a safety feature in controlling hazardous media.
Application:
Diaphragm valve, because the working medium contact is only the diaphragm and the valve body, both can use a variety of different materials, so the valve can be ideal to control a variety of working media, especially suitable for media with chemical corrosion or suspended particles.
