Introduction

Venturi Valve Data Sheet and Product Bulletin

The top hospitals, universities, and research facilities across the globe trust Triatek’s Venturi Valves to protect occupants from dangerous airborne pathogens and chemicals.

Triatek’s Venturi Valves maintain a desired airflow regardless of duct pressure. This is accomplished with a cone and spring-loaded piston inside the cone. As the duct pressure increases, the spring compresses and pushes the cone further into the shell. This mechanism keeps the volumetric flow rate constant as air travels through the valve and duct pressure varies.

Triatek Venturi Valves utilize fast-acting electric actuators that provide a rapid response to changing conditions. This rapid response ensures the airflow is maintained at desired levels, which is critical in areas requiring a specific threshold of air flow in order to protect individuals from airborne chemicals or particulates.

Valve Options

Construction Material: Aluminum or Stainless Steel

Triatek offers both aluminum and stainless steel Venturi Valves.

Coatings: Heresite® or Kynar®

Heresite® is a brown phenolic coating baked on exposed aluminum to minimize corrosion. Heresite® coatings provide resistance to a wide range of corrosives.  Kynar® coatings provide the best in chemical resistance with high levels of purity, and superior mechanical properties. It is often used as a lining or protective barrier in applications in which Heresite® is not sufficient.

Thermal Insulation

Often used for supply valves, thermal insulation decreases energy costs by reducing thermal losses.

Ganged Valves 

Valves can be ganged together to increase flow.

Flanges

Flanges can be added to valves to help make the installation process easier.

Valve Flow: Constant Volume or Actuated

Constant Volume Venturi Valves are used for biosafety cabinets, constant volume fume hoods, ventilated cabinets, and outside air regulation. Actuated valves are used in systems that adapt to a dynamic environment.

Air Pressure: Medium or Low 

Medium Pressure Venturi Valves (0.6” to 3” wc) allow for higher flows for a given valve size, while Low Pressure Venturi Valves (0.3” to 3” wc) require a smaller pressure drop across the valve for maintaining a constant flow.

Valve Closing: Partially Closed or Shut-Off

Partially Closed Venturi Valves allow for higher flows for a given valve size, while Shut-Off Venturi Valves allow the valve to close completely for equipment not currently in use, leading to energy savings.

Installation in Duct Work: Horizontal or Vertical

Triatek’s valves can be installed either horizontally or vertically. Customers should specify how the valve will be situated in the duct work, as vertically mounted valves are calibrated differently.

Valve Size

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