Features
There are two types of diaphragm valves:
Weir:  The Weir Diaphragm valve can be used for either off/on and throttling services
Straightway:  named also Straight-Thru is only used for on/off services.
- Non-stick property,Self sealing faces.
- High resistance to Thermal/Mechanical shock .
- Suitable for pressure and vacuum application .
- Easy to install, It is a quick opening valve.
- Long life and Zero maintenance .
- More economical than glass lined and special alloys.
- Carbon steel Diaphragm Valves are used on shut-off and throttling service for liquids, slurries and vacuum/gas.
- The seal is achieved by a flexible membrane, usually elastomer, and possibly reinforced with a metal part. The membrane is tensed by the effect of a stem/compressor with lineal movement until contact is made against the seal of the body.
- The operating parts of the diaphragm valve are isolated from the flow. This makes this valve suitable for viscous flows and also hazardous, abrasive and corrosive flows as its sealing system avoids any contamination towards or from the environment.
- Carbon steel Diaphragm Valves are available in a wide variety of metals, solid plastics, plastic, rubber and glass linings. They are well suited to the handling of multiple chemical applications both clear fluids as well as slurries.
- .The Carbon steel Diaphragm Valve has an extended use for applications at low pressures and slurry fluid where most other kinds of valves corrode or become obstructed.
- Can be tailor made to suit customer requirements

Brief Itntroduction:
-   Its main features are heavy-duty, robust construction, maintenance-free, easy replacement of components on site. Convenient, flexible and accurate open or close.
-   It is ideal products used in chlor-alkali, industrial in organic chemicals, metal and mining, nitrogen and phosphatic fertilizers, petroleum refining, pharmaceutical etc.
-   It is not applicable for diaphragm used in medium with hard particles, which will cause diaphragm damage and leakage.
-   The working temperature cannot exceed the specified range.
-   Open the diaphragm too frequent will influence the sealing performance
