The TSI Model CV Venturi Valves are designed to mechanically adjust to maintain a constant flow rate in the face of changing duct static pressures meaning that neither controllers or actuators are needed.
The Venturi Valve consists of a cone inside the valve body. A spring automatically positions of the cone on the valve shaft to achieve pressure independence. CV Venturi Valves have an equal-percentage characteristic over their specified flow rate. A mechanical valve dial permits direct reading of air volume allowing the flow to easily be reset if future requirements change.
Venturi Valves, unlike flow stations, do not require any straight duct runs to maintain flow accuracy. Venturi Valves can be mounted next to an elbow, transitions or branches without affecting accuracy. These volume venturi valves are therefore ideally suited to snorkels, canopies and other constant volume devices.
Venturi Valves must be ordered according to the desired flow rate and pressure drop across the valve.
