Working Principle Of Sanitary Diaphragm Valve

Sanitary Diaphragm Valve When the actuator causes the valve stem to rise, the diaphragm is lifted and the fluid can flow through the valve body to form a passage.
When the actuator causes the valve stem to fall, the diaphragm is pressed down and adheres to the bottom of the valve body weir or profile, thereby blocking the flow of fluid and achieving the shut-off function.
