Triatek’s Medium Pressure Constant Volume Venturi Valves are pressure independent and designed to maintain a constant flow rate regardless of the changing duct static pressure.
These valves maintain a constant CFM at a specific shaft position over a range of 0.6” 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 Medium 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. Click here for a chemical resistance comparison chart.
