The diaphragm is closeunder normal state,and that moment the diaphragm clung tothe valve body cavity,and closing off theflowpath throughthe pipeline.Whenthe diaphragm valbe have the requirement to clean or open,the valve stem moves upwards

according to themanualor pneumatic actuator equipment,spherical diaphragms naturally bend upwards,so that the valve is open and reach the requirement of cleanand open.Thediaphragm makethe lowerbody cavity and the upperchamber separated from thevabve cover,so that the stem atthe top of the diaphragm,disc media and otherparts from corrosion,eliminating theneed forpackingstructure,and no media leaks.The optimizevalve bodymadethe cleaningliquid flow out totally,so that don't have any entrapment.
