test


Lining layer: EDM test


Test and inspection according to BS6755 standard


Nominal pressure: PN (MPa)


Valve body: PN * 1.5 seal: PN * 1.1


Structural characteristics


Diaphragm valve is a special type of cut-off valve: 1, the opening and closing part of the elastic seal ensures that there is no internal leakage.


2, streamlined flow path 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 above the diaphragm, the valve stem and other parts are not eroded 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 has the characteristics of high strength and good corrosion resistance.
