| Application | Diaphragm valve is widely used on wine,dairy products,beverage,foodstuff industry,pharmacy etc,achieving the requirement of control and open/close for pipeline system. |
| Working principle | The diaphragm is closed under normal state,and the diaphragm close to the valve body cavity,and closing off the flow path through pipeline.when the diaphragm valve have the requirement to clean or open,the valve stem moves upwards according to the manual or pneumatic actuator equipment,spherical diaphragms naturally bend upwards.so that the valve is open and reach the requirements of clean and open; The diaphragm valve make the lower body cavity and the upper chamber separated from the valve cover,so that the stem of the top of the diaphragm,disc medium and other parts from corrosion,eliminating the need for packing structure,and no medium leaks, the optimize valve body made the cleaning liquid flow out totally,don’t have any entrapment. |
