The diaphragm valve is normally closed, where the diaphragm clings to the inner cavity of the valve body and closes the pipeline flow path. When the diaphragm valve needs to be cleaned or opened, the stem moves upward by rotating the handwheel manually or driving the pneumatic control actuator, and the spherical diaphragm bends upward, so that the valve is open and reach the requirement of clean and open. The diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the stem and valve core located in the upper part of the diaphragm are not corroded by the medium, thus the packing sealing structure is eliminated and the medium leakage will not occur. Optimized valve body design made the cleaning liquid discharge fully, do not form a retention phenomenon.

Applications
Diaphragm valves, manually or pneumatically operated, are specifically designed for use on hygienic and aseptic processes in the pharmaceutical industries
The valve is excellent for flow control as well as for open/cloase duties.
Design and features
The diaphragm valve are better in feature of flow in comparison with other valves. It is easier to clean up and better to process the substance with particles. the phenomenon of air pocket is rare during application of flow control.
