The outstanding feature of Sanitary Diaphragm Valve is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve disc and other parts above the diaphragm are not corroded by the medium, the packing sealing structure is omitted, and there will be no leakage of the medium. The specific characteristics of the electric sanitary diaphragm valve are as follows:

1. The diaphragm made of soft seals such as rubber or plastic has good sealing performance. Since the diaphragm is a wearing part, it should be replaced regularly depending on the characteristics of the medium;

2. Due to the limitation of the diaphragm material, the sanitary diaphragm valve is suitable for low pressure and relatively low temperature occasions;

3. The sanitary diaphragm valve can be divided into six types according to the structural form: house type, direct current type, stop type, straight-through type, gate type and right angle type; the connection form is usually flange connection; according to the drive mode, it can be divided into manual, electric and pneumatic types, among which pneumatic drive is divided into normally open, normally closed and reciprocating types;

4. It is generally not suitable for use in pipelines with temperatures above 60 degrees and for conveying organic solvents and strong oxidizing media, nor in pipelines with higher pressures.
