Working Principle
When the valve is in the open position, the diaphragm is in a relaxed state, allowing fluid to flow through the valve body. To close the valve, the actuator applies force to the diaphragm, causing it to flex and press against the valve seat, thus blocking the flow path of the fluid. The unique design ensures that there is no direct contact between the moving parts and the process fluid, minimizing the risk of contamination.
Design Features and Advantages
Hygienic Design: The smooth interior surface of the stainless - steel body and the absence of dead - legs (areas where fluid can stagnate) make it easy to clean. This is crucial for preventing the growth of bacteria and other contaminants.
Leak - Proof: The diaphragm provides a reliable seal, preventing leakage both internally (between the fluid path and the actuator) and externally. This is especially important in applications where product loss or contamination of the surrounding environment is unacceptable.
Corrosion Resistance: The stainless - steel construction and the use of corrosion - resistant diaphragm materials make these valves suitable for handling a wide range of fluids, including those with acidic or alkaline properties.
Low - Maintenance: With fewer moving parts in contact with the fluid, the valves require less frequent maintenance compared to some other valve types. This reduces downtime and maintenance costs in production processes.
Applications
Food and Beverage Industry: Used in processes such as dairy production (for milk handling, pasteurization lines), brewing (beer and wine production), and juice processing. They ensure that the products remain free from contamination throughout the production, storage, and distribution stages.
Pharmaceutical Industry: Essential in pharmaceutical manufacturing for handling raw materials, active pharmaceutical ingredients (APIs), and in - process products. They help maintain the sterility required in drug production, filling, and packaging operations.
Biotechnology: In biotech research and production facilities, for handling cell cultures, reagents, and other biological fluids. The hygienic design and leak - proof nature of these valves are critical for maintaining the integrity of biological processes.
