The primary benefit of the use of venturi air valves is the fact that Venturi valves offer the ability to maintain a desired air flow regardless of duct pressure. This is accomplished though a proven system which uses a spring loaded cone housed inside a piston within the cone. As the duct pressure increases, the spring compresses and pushes the cone further into the shell. Doing so keeps the CFM constant as air travels through the valve while also maintaining duct pressure.
Triatek Venturi Valves use either electric or pneumatic actuators. The electric actuator has a rapid response to changing conditions and pressures and can adjust the overall cone position within the shell in .5 - 1 second. Doing so ensures that the airflow is maintained at desired levels which is critical in areas that need a certain threshold of CFM in order to protect employees for airborne particulates.
Flow rates are preprogrammed into the controller mounted on the exterior of the cone and therefore, internal flow probes are not required to monitor flow rates within the cone. Not using internal flow probes eliminates annual cleaning and calibration measures which is common with valves that employ internal flow probes.
