Stainless Steel quick release butt weld manual flow control u type diaphragm valve
A stainless steel sanitary zero dead leg diaphragm valve is a valve that uses a diaphragm to control the flow of liquids, gases, and semi-solid media while preventing contamination: Diaphragm: A flexible diaphragm that's connected to a compressor by a stud. When the valve shuts off, the diaphragm pushes against the bottom of the valve body instead of pinching the liner closed. Zero dead leg:A design that eliminates dead legs, which are sections of piping systems that can stagnate due to a lack of flow. Stainless steel:Corrosion-resistant material that can also withstand high pressure and chemical abrasion.
Work Principle
The zero dead leg diaphragm valve operates on the principle of preventing fluid stagnation and contamination in pharmaceutical, food processing, and biotechnological applications where hygiene is critical. Its design ensures that there are no stagnant areas or pockets (dead legs) where fluids can accumulate and potentially harbor bacteria or other contaminants. This is achieved through a specific construction where the valve body and diaphragm seal eliminate any areas where fluids could remain after flushing or sterilization procedures. Typically made from materials such as stainless steel or other corrosion-resistant alloys, these valves are essential for processes requiring high levels of cleanliness and sterility. They are used to control the flow of liquids and gases in systems where maintaining purity and preventing cross-contamination are paramount, such as in pharmaceutical production lines or food processing plants. The zero dead leg design ensures thorough cleaning and sterilization, meeting stringent regulatory requirements and ensuring product integrity.

Application
Diaphragm valves, manually or pneumatically operated, are specifically designed for use in sanitary and aseptic processes in the medical and pharmaceutical industries. Very good performance in controlling the flow rate of the small flow piping line. The valves are suitable for applying in high flow rate, high corrosivity, high viscosity fluid.
