Achieve rapid, reliable, and washdown-safe fluid automation with the Aomite Sanitary Pneumatic Butterfly Valve.
Unlike standard automated valves that use aluminium or plastic drive heads, this premium unit features a heavy-duty, fully enclosed Stainless Steel Pneumatic Actuator. This ensures the entire valve assembly can withstand harsh external washdowns and corrosive chemical environments typical in breweries, dairies, and pharmaceutical plants. The internal piston mechanism instantly converts pneumatic air pressure into a precise 90-degree rotation of the valve shaft. Available in Normally Open (NO), Normally Closed (NC), and Double-Acting (Air-to-Air) configurations, it integrates seamlessly into your facility's PLC system. Standard Tri-Clamp connections ensure ultra-hygienic, zero-dead-leg fluid routing.

Washdown Compatibility & Corrosion Resistance
In food, dairy, and pharmaceutical plants, equipment is subjected to daily high-pressure washdowns using harsh caustic and acidic foaming cleaners. Standard aluminium actuators will quickly oxidise, pit, and shed paint or metal flakes into the cleanroom environment. A full stainless steel actuator is completely immune to these cleaning chemicals, ensuring long-term structural integrity and maintaining a sterile, rust-free exterior.
Normally Closed (NC): Spring-return to the closed position. Uses air to open. It acts as a fail-safe to shut off the fluid if air pressure is lost.
Normally Open (NO): Spring-return to the open position. Uses air to close. Ideal for critical cooling lines.
Double Acting / Air-to-Air (AA): Uses compressed air to both open and close the valve. It provides maximum torque but lacks a mechanical spring fail-safe. (Note: Do not confuse this with "gas" lines; it operates purely on compressed plant air.)
