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.
