Description
Description
The 304 Rotary Airlock Valve is a precision-engineered component designed to regulate dust discharge in industrial dust collection systems while maintaining consistent airflow and pressure integrity. Crafted from corrosion-resistant 304 stainless steel, this valve ensures durability in humid, high-temperature, or mildly corrosive environments (e.g., wood dust, cement residues). Its cylindrical rotor and sealed housing prevent air leakage between the hopper and discharge point, enabling continuous material flow without system pressure loss. Ideal for handling fine particulates, powders, and granules in woodworking, metalworking, and cement processing, the valve’s rugged construction minimizes wear and downtime. Suitable for operating temperatures up to 400°C (752°F), it optimizes dust collection efficiency and material handling reliability.
Key Components
>Housing – The main body, typically made of cast iron or stainless steel, providing structural support and durability.
>Rotor – A rotating component with multiple vanes (blades) that controls material discharge while maintaining an airlock seal.
>End Plates – Fixed plates at both ends of the housing, securing the rotor and supporting the bearings.
>Bearings – Support the rotor shaft, ensuring smooth and stable rotation.
>Shaft – Connects the rotor to the drive system, transmitting motion.
>Drive System – Includes an electric motor and gearbox that power the rotor’s rotation.
>Seals – Prevent dust and air leakage around the rotor and shaft, ensuring airtight operation.
>Inlet & Outlet Flanges – Square-shaped openings for dust or material entry and exit, designed for secure connection to the dust collector system.
>Inspection Ports (Optional) – Allow easy
maintenance and monitoring of internal components.
