Venturi Valves are mechanical pressure independent control valves designed specifically for room pressure and fume hood control applications.

• The highly engineered internal plunger assembly ensures the valve will respond to changes in duct static pressure in less than one second, while turndown ratios reaching 20:1 serve to maximize energy savings in unoccupied or minimum flow set-points.
• Each valve is factory calibrated, then characterized by flow to valve position using the latest N.I.S.T. traceable equipment to ensure dependable and repeatable valve accuracy. Price venturi valves are accurate to +/-5% of flow when operated within the designed pressure range. Valve accuracy is unaffected by inlet conditions and does not require any minimum distance of straight duct on the inlet or outlet of the valve.
• Available in constant or variable air volume configurations, the venturi valve is able to control flow without the need for measuring devices in the airstream, eliminating the possibility of lint or other airborne particulates interfering with the control or accuracy of the valve. The valve provides electronic flow feedback using a precision potentiometer to output a VDC signal linearly proportional to airflow.
• Venturi valves are available with integrated silencers with full sound performance data tested as a complete assembly. Hot water coils are AHRI 410 certified and electric coils are ETL certified to UL1995 as a complete assembly and/or HW or electric reheat coils as AHRI certified assemblies. All silencers and reheat coils are manufactured in-house with designs optimized for close coupling with the valve.
