Fifth, the characteristics of the rubber-lined diaphragm valve G41J:
Structural characteristics: Diaphragm valve is a special type of cut-off valve.
1. Opening and closing parts of elastic seals to ensure that there is no internal leakage;
2. Streamlined flow channel makes pressure loss small.
3. There is no filler letter, so there is no leakage.
4. The valve body and cover are separated by the middle diaphragm, so that parts such as the valve cover and the valve stem 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 all kinds of media and have good corrosion resistance.
