Universal valve module
Each Venturi Air Valve comes with a UVM1000 linearization module that provides fast and simple control of the air valve. You can command with a 0 VDC to 10 VDC control signal which scales to represent 0% to 100% of the air valve’s minimum to maximum CFM range. The UVM1000 provides a 0 VDC to 10 VDC position feedback signal as confirmation the actuator has been repositioned to meet the target CFM setpoint. For example, if 0 VDC to 10 VDC is equal to 0 CFM to 1000 CFM, a 750 CFM setpoint requires a 7.5 VDC command signal sent to the UVM1000. The command signal drives the air valve to the 750 CFM position and returns a 7.5 VDC position feedback signal as confirmation.
For more information, refer to the UVM-1000 Product Bulletin (LIT-12013292) and the UVM-1000 Installation Guide (LIT-12013155).
Aluminum or stainless steel
Venturi Air Valves are made of aluminum for general exhaust or supply applications. A 316 stainless steel (SS316) option is also available for environments with highly corrosive or dangerous chemicals in the air stream.
Heresite
Heresite is a brown phenolic coating baked on exposed aluminum to minimize corrosion. Heresite coatings provide resistance to a wide range of corrosives.
Thermal insulation
You can use thermal insulation for supply valves. Thermal insulation decreases energy costs by reducing thermal losses and prevents duct condensation.
Constant volume
Constant volume (CV) Venturi Air Valves provide a single CFM set point for applications that require only one air flow set point. CV valves do not come with a controller or actuator.
Medium or low pressure
Medium pressure Venturi Air Valves (0.6 in. W.C. to 3 in. W.C.) allow for higher flows for a given valve size, while low pressure Venturi Air Valves (0.3 in. W.C. to 3 in. W.C.) require a smaller pressure drop across the valve to maintain a constant flow.
Partially closed or full shut-off
Partially closed Venturi Air Valves allow for higher flows for a given valve size, while full shut-off Venturi Air Valves allow the valve to close completely for zero flow application requirements.
Horizontal or vertical
You can specify how the air valve is situated in the duct work. For example, horizontal, vertical up flow, or vertical down flow. Each orientation is calibrated differently to account for the effects of gravity on the spring-loaded cone assembly to ensure mechanical pressure independence is maintained.
Size
Titus offers 8 in., 10 in., 12 in., and 14 in. (203 mm, 254 mm, 305 mm, and 355 mm) diameter valves for a variety of applications.
Ganged valves
To increase flow, gang air valves together.
