Fluorine diaphragm valve

Close
√Specification √Product feature

  • Diameter: DN15~300
    Pressure: PN6~16
    Materials: carbon steel, stainless steel, gray cast iron
    Temperature: -29~425 ℃
    Standard: GB/T 12235
    Media: water, steam, gas, oil, corrosive media
    Connection method: flange

  • The most prominent feature 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 located above the diaphragm are not corroded by the medium, eliminating the need for corrosion

    The packing sealing structure is adopted, and there will be no leakage of the medium.

    A diaphragm made of soft sealing materials such as rubber or plastic has good sealing performance. Due to the fact that the diaphragm is a vulnerable component, it should be replaced according to the characteristics of the medium,

    2. Due to the limitations of diaphragm materials, diaphragm valves are suitable for low pressure and relatively low temperature situations.

    3. Diaphragm valves can be divided into six types according to their structural forms: roof type, DC type, globe type, through type, gate type, and right angle type; The connection form is usually flange connection;

    According to the driving mode, it can be divided into three types: manual, electric, and pneumatic. Among them, pneumatic driving is further divided into three types: normally open, normally closed, and reciprocating.

    4. It is generally not suitable for use in pipelines with temperatures above 60 degrees Celsius and transporting organic solvents and strong oxidizing media. It is also not recommended to use diaphragm valves directly in pipelines with higher pressures

    A valve used to open or isolate airflow in a fluid system with a pressure range of 1.3x10-5-2.5X106Pa.
