The closing and opening of the plastic diaphragm valve is realized by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm presses down and closes the valve channel. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises and the valve channel is opened. The valve has no valve stem, sealing gasket, directional seat, etc. The moving parts in the channel are diaphragms, so there is no corrosion and locking phenomenon, and it has higher stability. A variety of structural forms and control forms can be applied to a variety of fluid control needs.

 

Plastic diaphragm valve is widely used in industrial automation systems for strong acid, strong alkali, strong corrosion, high viscosity, containing particles Flow regulation of media with fibers and toxic and non polluting media.
