It is special for controlling the noncorrosive or the strong corrosive media. Its body inner surface is unlined or lined with different fluorine plastics which can be selected to suit with different working temperatures and fluid pipelines.
Suitable temperature: ¡Ü85¡æ, ¡Ü100¡æ, ¡Ü120¡æ, ¡Ü150¡æ according to the materials of lining and diaphragm
There being no weir in through way type diaphragm valves, fluid passes straightly through inside valve cavity, so that they are especially applicable for viscous fluid, cement grout and perceptible fluid. Compared with weir type diaphragm, the diaphragm stroke of through way type is comparatively longer. That is to say, this structure can limit the selection range of synthetic rubber.
Design & manufacture: GB12239
Face to face: JB1688, GB12221
Flange ends: JB78, GB4216
Test for lining layer: Electro spark detecting
Test: GB/T13927
