Rotary Valves
Precision Air Lock & Feeding Systems
Oswar Rotocorp Rotary Valves are engineered to control bulk solids while maintaining pressure differential between process zones. Designed for continuous industrial duty, they deliver stable discharge, minimal leakage, and long service life in demanding environments.
From fine powders to abrasive minerals, our Rotary Valve systems ensure reliable material transfer without compromising process efficiency.
What Rotary Valves Do
- Pressure isolation between upstream and downstream zones
- Controlled volumetric discharge
- Leakage minimization
- Stable pneumatic conveying performance
- Process energy efficiency support
A Rotary Valve is not just a discharge device.
It is a pressure-control component that directly influences plant efficiency, emissions, and operational stability. At Oswar Rotocorp, every Rotary Valve is engineered to deliver:
- Long-term reliability
- Reduced leakage
- Stable feeding
- Lower maintenance cycles
- Consistent process performance
