The most prominent feature is that the diaphragm separates the lower body cavity from the upper cover cavity, so that the stem, disc and other parts above the diaphragm are not corroded by the medium, eliminating the packing seal structure, and no leakage of the medium.

1. Diaphragm made of rubber or plastic and other soft sealing materials has good sealing performance.As the diaphragm is wearing parts, should be depending on the characteristics of the medium and periodically replaced.

2. Limited by diaphragm material, diaphragm valve is suitable for low pressure and relatively low temperature occasions.

3, diaphragm valve can be divided into: house type, direct flow, cut-off type, straight through type, gate type and right Angle type six;The connection form is usually flange connection;According to the driving mode can be divided into manual, electric and pneumatic three, pneumatic drive is divided into normally open, normally closed and reciprocating three.

4. Generally, it is not suitable for pipelines where the temperature is higher than 60 ° c and organic solvents and strong oxidation medium are transported, and it is also not suitable for pipelines with higher pressure. Diaphragm valve is used to open or block airflow in the fluid system of 1.3×10-5 ~ 2.5X106Pa.
