Product Description

DN8 Zero Static Sanitary Stainless Steel Manual Diaphragm Membrane Valve (JN-DV2008)

 

A is a valve designed to control fluid flow by manually pressing a flexible diaphragm to open or close the passage. It is widely used in pharmaceutical, food, and beverage industries where hygiene is critical. The valve's sanitary design ensures no contamination, while the manual operation allows precise flow control. Its easy-to-clean surface supports strict sanitation requirements. The valve provides leak-tight sealing and is ideal for handling corrosive or viscous fluids in sensitive processes.

Working Principle
A stainless steel sanitary manual diaphragm valve works by manually pressing a diaphragm to control flow. First, the operator turns the handwheel, which moves the diaphragm downwards, creating a seal against the valve seat. This action stops fluid flow completely. When the handwheel is turned back, the diaphragm lifts, allowing fluid to pass smoothly through the sanitary, smooth flow path. The diaphragm's flexibility prevents contamination and ensures leak-tight sealing. This manual control enables precise regulation of flow in hygienic processing systems.
