G49J Diaphragm Valve Company

Three-way diaphragm valve use: This valve is specially used to control non-corrosive or general corrosive media. The inner cavity of the valve is not lined or covered with various rubbers for selection, and is suitable for different working temperatures and fluid pipelines.

Applicable temperature: ≤85℃, ≤100℃, ≤120℃, ≤150℃ (according to lining and diaphragm material)

Pressure rating: PN1.0

Structural features

Three-way diaphragm valve is a special form of stop valve;

1. The elastically sealed opening and closing parts ensure that there is no internal leakage;

2. The streamlined flow channel makes 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 and valve stem 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 media and has good corrosion resistance.
