Low Pressure Constant Volume Venturi Valve
The Low Pressure Constant Volume Venturi Valve is designed to maintain a constant flow rate regardless of the changing duct pressure.
This valve maintains a constant CFM at a specific shaft position over a range of 0.3” to 3” wc.* As static pressure increases or decreases, the internal cone adjusts to maintain a constant volume of air.
Constant Volume Venturi Valves are typically used in applications that include:
- Biosafety cabinets
- Constant volume fume hoods
- Ventilated cabinets
- Outside air regulation
The Low Pressure Constant Volume Venturi Valve arrives on-site calibrated and ready for installation. For installations that will encounter harsh chemicals in the air stream, Triatek offers Kynar® and Heresite® coatings to prevent corrosion. Access the chemical resistance comparison chart here.
*Vertical “up” Low Pressure Venturi Valves range 0.4” to 3” wc.
