Introduction to g49w | g49f three-way diaphragm valve and g49j three-way rubber lined diaphragm valve

G49j three-way rubber lined diaphragm valve is specially used to control non corrosive or general corrosive media. The surface of the inner cavity of the valve body is unlined or covered with various kinds of rubber, which is suitable for different working temperatures and fluid pipelines. The diversity of lining materials can be applied to various media and has good corrosion resistance. The valve body and cover are separated by the middle diaphragm, so that the valve cover and valve rod parts above the diaphragm are not eroded by the medium. The diaphragm valve is a special form of stop valve.

Structural features of g49w | g49f three-way diaphragm valve and g49j three-way rubber lined diaphragm valve

Three way diaphragm valve is a special type of stop valve;

1. The opening and closing parts with elastic seal ensure no internal leakage;

2. Streamlined flow passage makes the pressure loss small;

3. There is no stuffing box, so there is no leakage;

4. The valve body and cover are separated by the middle diaphragm, so that the valve cover and valve rod parts above the diaphragm are not eroded by the medium;

5. The diaphragm can be replaced and the maintenance cost is low;

6. The diversity of lining materials can be applied to various media and has good corrosion resistance.
