Venturi air valves are custom built to meet specific application requirements for each customer project. The selection process has several steps to ensure that you select the correct Venturi air valve configuration. Venturi air valves are built according to their SKU number. The ordering guide helps you select the correct SKU. Ensure you select the correct Venturi air valve configuration to meet your application requirements. For guidance on how to select the correct Venturi air valve SKU for your application requirements, see the following steps:

  1. Locate the project air valve schedule and determine the design pressure rating. Choose either medium pressure or low-pressure Venturi air valves.
  2. Use the air valve schedule to determine the valve diameter size. Ensure the valve meets the maximum CFM setpoint. If it does not meet the maximum CFM, you may need to gang the valves together in a double, triple, quadruple or six configurations to increase the air flow capacity.
  3. Cross-reference with the Venturi air valve flow rates to ensure the selected Venturi air valve size and pressure meets the minimum and maximum CFM setpoints on the air valve schedule.
  4. Confirm the final orientation for Venturi air valve installation so that the factory characterization assembles the correct application.
  5. The stakeholders review and approve the valve configuration before production begins. A customer supplied tag file ensures that the selected Venturi air valve configuration meets the application requirements.
  6. If the application needs are not clear, contact your sales representative for guidance and support.
Note: Because each Venturi air valve configuration is custom built, the valves cannot be resold to other customers. Non-defective Venturi air valve orders built for customers cannot be returned for credit or refund.

Note:
  • You cannot gang flanged valves together.
  • Contact Titus Sales for special actuator requirements.
  • When you order constant volume (CV) valves, include the required flow volume. Specify CFM for this purpose.
  • Constant Volume valves do not come with a UVM or any electronic components.
  • 14 in. valves are not available in full shut-off (Type = F) or SS316 (Material = S) at this time.
  • Low pressure (Pressure = L), full shutoff (Type = F) valves are not available in vertical upflow orientation (Airflow = U).
  • Vertical upflow (Airflow = U) low pressure (Pressure = L) valves maintain flow from 0.4 in. W.C. to 3 in. W.C.
