Product Description
It is specially used to control non-corrosive or strong corrosive media. The inner cavity surface of the valve is unlined or covered with various fluoroplastics, suitable for different working temperatures and fluid pipelines.
Applicable temperature: ≤85ºC, ≤100ºC, ≤120ºC, ≤150ºC, (according to lining and diaphragm material)
Pressure rating: 0.6, 1.0, 1.6
Structural features
Diaphragm valve is a special form of shutoff valve
1. Resiliently sealed opening and closing parts to ensure no internal leakage;
2. Streamlined runner. Make the pressure loss small;
3. There is no stuffing box, so there is no leakage;
4. The valve body and the cover are separated by the middle diaphragm, so that the valve cover, valve stem and other parts above the diaphragm are not corroded by the medium;
5. The diaphragm can be replaced and the maintenance cost is low;
6. The variety of lining materials can be applied to various restraints and has good corrosion resistance.
