Sanitary Clean Lock Rotary Valve


Sunco's Clean Lock Rotary Airlock is designed for sanitary/hygienic applications, where cleanliness is a primary concern. It is a modular design engineered specifically for the food, chemical and pharmaceutical industries, where cleanliness, both internal and externally, must be to a high standard.


All internal and external surfaces are fully machined, creating a smooth surface with no lodgement points.  A quick-release rotor is standard, which allows for easy cleaning with minimal downtime.


The drive is typically direct-coupled, which makes the valve more compact and eliminates the need for motor mounting plates, bosses, chains and sprockets, which may otherwise contaminate the process and complicate the cleaning process.
