Hygienic diaphragm valves are specially designed for precise flow control and isolation in sanitary and clean process applications. These valves use a flexible diaphragm to regulate flow, completely separating the process media from the valve actuator and internal mechanical components, ensuring maximum hygiene and contamination-free operation.

The valve body is manufactured from high-grade stainless steel (SS316 / SS316L) with smooth internal surfaces and a crevice-free design. This makes hygienic diaphragm valves ideal for food, dairy, beverage, pharmaceutical, and biotechnology industries, where strict cleanliness and process safety are essential.

Hygienic diaphragm valves are widely used for on/off control, throttling, and isolation, especially in applications involving corrosive, viscous, or sensitive media. They are fully compatible with CIP (Clean-in-Place) and SIP (Sterilize-in-Place) systems.
