A sanitary manual butterfly valve is a flow control device with a disc-shaped closing element (butterfly plate) that rotates around its own axis within the valve body to open, close, or regulate flow. Designed for hygienic applications, these valves are widely used in industries such as dairy, beverage, pharmaceutical, and food processing where clean-in-place (CIP) and sterile environments are essential.
Typically, the valve operates with a rotation angle of less than 90°, allowing for quick and efficient operation. The installation of a worm gear reducer enables self-locking and precise positioning of the disc, enhancing control and sealing reliability even under low pressure.
Quick and effortless operation
Low fluid resistance and pressure drop
Simple, compact, and lightweight design
Excellent sealing performance at low pressures
Ideal for frequent operation and slurry transport
Optional manual handle or actuator for automation
In industrial applications requiring higher pressure and temperature resistance, sanitary manual butterfly valves are made with carbon steel bodies and metal-sealed discs, replacing traditional rubber seals. These high-performance butterfly valves are commonly used in flue gas systems, smoke ducts, and gas pipelines.
