Universal valve module

Figure 1. 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 set point requires a 7.5 VDC command signal sent to the UVM1000. The command signal drives the 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).

Valve mounted room level controller

Figure 2. Valve mounted room level controller

For authorized facility explorer dealers, the Venturi Air Valves can be ordered with a factory mounted FX CCM09090 room level controller on the valve body. This reduces the need for an additional wall mounted panel in the critical space and makes installation easier. The valve mounted controller becomes the central node in the room for connection to all other devices. It is best practice to designate the location of the controller onto the valve with the easiest access, or the general supply.

For more information, refer to the Venturi Air Valve with UVM1000 Installation Guide (LIT-12014273), the F4-CC Critical Environment Equipment Controllers Catalog Page (LIT-1901177), and the F4-CC Critical Environment Equipment Controller Installation Guide (Part No. 24-10143-02244) on Knowledge Exchange.

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.


Figure 3. Heresite coated valve

Heresite is a brown phenolic coating baked on exposed aluminum to minimize corrosion. Heresite coatings provide resistance to a wide range of corrosives.


Figure 4. Kynar coated valve

Kynar provides excellent chemical resistance. Kynar is often used as a protective coating in applications where phenolic coating is not sufficient.

Thermal insulation

You can use thermal insulation for supply valves. Thermal insulation decreases energy costs that reduces thermal losses and prevents duct condensation.

Constant volume

Figure 5. Constant volume lateral front Venturi Air Valve

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 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 Valves allow the valve to close completely for zero flow application requirements.

Horizontal or vertical

You can specify how the valve is situated in the duct work. For example, horizontal, vertical upflow, or vertical downflow. 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.


Triatek offers 8 in., 10 in., 12 in., and 14 in. diameter valves for a variety of applications
