Brief introduction of g46j/g46x/g46f straight through diaphragm valve

The straight through rubber lined diaphragm valve is specially used to control non corrosive or general corrosive media. The inner surface of the valve body is unlined or covered with various kinds of rubber. The straight through rubber lined diaphragm valve is suitable for different working temperatures and liquid pipelines.

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

Structural features of g46j/g46x/g46f straight through diaphragm valve:

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 channel, making 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, valve rod and other 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 the characteristics of high strength and good corrosion resistance.
