Working Principle Of Sanitary Diaphragm Valve

Sanitary Diaphragm Valve is a special type of shut-off valve. Its opening and closing parts are a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving components, so it is called a diaphragm valve. It is widely used in sanitary brewing, dairy products, beverages and other food industries as well as the pharmaceutical field under aseptic conditions to achieve the control and opening/closing tasks of pipeline fluids.
Working principle of sanitary quick-install diaphragm valve:
The diaphragm valve is in a closed state under normal conditions. At this time, the diaphragm is close to the inner cavity of the valve body, closing the path to the pipeline fluid. When the diaphragm valve needs to be cleaned or opened, the valve stem is driven upward by manually rotating the handwheel or driving the pneumatic control actuator, and the spherical diaphragm bends upward, so that the valve forms a conductive state.
The purpose of cleaning and opening can be achieved. The diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve core and other parts located on the upper part of the diaphragm are not corroded by the medium, eliminating the packing sealing structure, and no medium leakage. The optimized valve body design allows the cleaning liquid to be completely discharged without forming a stagnation phenomenon.
The sanitary diaphragm valve uses reinforced silicone rubber, and the valve body is polished by high-speed finishing, with a finish of Ra0.2μm. It is widely used in systems with high aseptic requirements such as biology, pharmaceuticals, food, and electronics.

Application: It can be used from the food industry to the high-end pharmaceutical industry. It is suitable for many pipeline connectors such as dairy machinery engineering installation, food machinery engineering installation, and pharmaceutical engineering machinery.
The sanitary diaphragm valve is the most trustworthy product in the field of biopharmaceuticals. Various media are made with special requirements, and it is smooth, seamless, dead corner, absolutely high cleanliness and a complete quality assurance system. As a result, it is widely used in the field of biopharmaceuticals and systems with high aseptic requirements such as water for injection, and is specially made for GMP requirements.
Product features:
1. The sanitary diaphragm valve has a simple structure, small size, light weight, small flow resistance, and good energy-saving effect. When the medium flows through the valve, it is equivalent to flowing through a straight pipe, and the fluid resistance is minimal.
2. The direction of the fluid in and out of the valve can be selected arbitrarily, and it has a bidirectional effect.
3. The connection methods of sanitary pipe fittings are: internal thread, flange, butt welding, plug welding, quick installation, etc.! It can be installed in horizontal pipes and vertical pipes.
4. Easy to operate, fast switching, the handle only needs to be turned 90 degrees to achieve switching. Pneumatic and electric can be adjusted at will.
5. The anti-leakage effect is excellent, and the switch life can be 5-10 times higher than other equipment.
