Diafragmaventiler

Diafragmaventiler, also known as diaphragm valves, are a type of industrial valve that uses a flexible diaphragm to control the flow of fluid. This diaphragm is typically made of rubber, PTFE, or other elastomeric materials and is actuated by a handwheel, lever, or an automated actuator. As the actuator moves, it either compresses the diaphragm against a weir or saddle, stopping the flow, or lifts it away, allowing flow. This mechanism offers several advantages, including excellent sealing capabilities and the ability to handle corrosive or abrasive fluids without leakage. The smooth, unobstructed flow path when the valve is fully open also makes them suitable for slurries and viscous media.

These valves are commonly found in industries such as chemical processing, pharmaceuticals, water treatment, and food and beverage production. Their simple construction with few moving parts contributes to their reliability and low maintenance requirements. Diafragmaventiler are designed to prevent contamination of the fluid, as the working mechanism is isolated from the flow path. This makes them ideal for hygienic applications. They are available in various sizes and configurations to suit different pressure and temperature requirements, and their sealing properties are particularly effective in preventing fugitive emissions.
