Product Details

    EPDM Rubber Diaphragm Valve

 

The rubber-lined diaphragm valve straight-through type is suitable for controlling non-corrosive or general corrosive media. The inner cavity surface of the valve is unlined or covered with various rubbers to choose from. It is suitable for different working temperatures and liquid pipelines. There is some advantage as follows:

1. The opening and closing parts with elastic sealing 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, 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 diversity of lining materials can be applied to various media and has the characteristics of high strength and good corrosion resistance.
