Low Pressure Partially Closed Venturi Valve

Triatek’s Low Pressure Partially Closed Venturi Valve is an energy-efficient valve option constructed primarily with heavy gauge aluminum and features a blend of stainless steel and Teflon® components to extend valve life.
These valves are pressure independent and maintain a constant CFM at a specific actuator position over a range of 0.3” to 3” wc* with accuracy of +/- 5%. They do not require long straight runs for proper operation. Single valve flow rates range from 35 – 1400 CFM depending on the valve size.
The Low Pressure Partially Closed 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.
