ENGINEERED FOR THE PROCESS
Air Purge Rotary Valve Design
Air purge and sealing options for demanding powder applications.
Air Purge Rotary Valve Design from Sercan Machinery
Our engineering team reviews the handled material, particle size, bulk density, capacity, temperature, pressure differential and installation interface before recommending a configuration. This reduces leakage, unstable feeding, wear and avoidable maintenance.
Typical configuration scope
- Body and rotor material selection
- Rotor clearance, blade and sealing configuration
- Round, square or custom flange interfaces
- Gearmotor, speed and control requirements
- Wear-resistant, polished or coated contact surfaces
Common applications
- Pneumatic conveying
- Powder feeding
- Dust collection discharge
- Silo and hopper outlets
Material options
- Carbon steel
- Stainless steel
- Wear-resistant options
- Custom contact surfaces
APPLICATION NOTES
Engineering considerations for Air Purge Rotary Valve Design
The main design objective is keeping fine or heat-sensitive powder away from shaft seals. Confirm purge gas type, available pressure, seal location and product compatibility before fixing the valve size, rotor and drive arrangement.
Purge flow must be controlled so it protects the seal without disrupting process balance. Sercan reviews these details against capacity, installation interface and maintenance access before issuing a project drawing.
Recommended project checks
- Provide representative material and bulk density data.
- State normal and maximum temperature and pressure conditions.
- Confirm flange dimensions, available height and drive orientation.
- Define the expected duty cycle and maintenance target.
TECHNICAL FAQ
Questions before selection
Can the valve match an existing brand or model?
Yes. Send the existing model, nameplate, interface dimensions and operating conditions.
Which information affects capacity?
Rotor volume, speed, filling efficiency and bulk density all affect output.
