Sanitary diaphragm valves are widely used on wine, dairy products, beverage, foodstuff industry, pharmacy etc, achieving the requirement of control and open/close for the pipeline syestem.
The diaphragm valve is closed under normal state, and that moment the diaphragm clung to the valve body cavity, and closing off the flow path through the pipeline.
When the diaphragm valve has 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 requirement of clean and open.
The diaphragm make the lower body cavity and the upper chamber separated from the valve cover, so that the stem at the top of the diaphragm, disc media and other parts from corrosion, eliminating the need for packing structure, and no media leaks. the optimize valve body made the cleaning liquid flow out totally, so that don't have any entrapment.
