What are the types of air valves?
There are three basic types of air valves standardized in American Water Works Association (AWWA) Standard C512-15: “Air-Release, Air/Vacuum, and Combination Air Valves for Water and Wastewater Service.”
What is an air release valve?
Air Release Valves are used to automatically vent the air that can become trapped in any pipeline conveying fluid. They should be placed at strategic high points along the pipeline, where trapped air can accumulate.
What is venturi air valve?
Triatek’s Venturi Valves maintain a desired airflow regardless of duct pressure. 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.
What are Phoenix valves?
Phoenix Controls offers solutions for all critical airflow applications whether it’s research in wet chemistry laboratories, the multi-discipline environments of Life Sciences, or the wide-range of healthcare spaces requiring proper directional airflow.
Do I need an air release valve?
Air release valves protect the pipeline system and maintain its efficiency. These valves are perfect for quickly venting large volumes of air during filling or startup. They also allow air back into the pipeline during emptying. This is important because some pipe materials can collapse under negative pressure.
What is the purpose of air valve?
Air valves are hydromechanical devices designed to automatically release air and wastewater gases or admit air during the filling, draining or operation of liquid piping systems for water and wastewater services.
What is a venturi valve used for?
VAV boxes control the volume of heated or cooled air entering a space in order to manage temperature, humidity, and ventilation. The boxes are calibrated dampers that use a butterfly/blade device to regulate airflow into a space.
What is a venturi used for?
Venturi are used to measure the speed of a fluid, by measuring the pressure changes from one point to another along the venture. A venturi can also be used to inject a liquid or a gas into another liquid.
How do Phoenix valves work?
It all comes down to the highly accurate and extremely stable venturi air valve that Phoenix Controls uses. By placing an obstruction (a cone in this case) inside the venturi valve, the flow through the valve can be varied. The flow through the Phoenix Controls air valve is accurate to within +/- 5% of any set point.
What is the difference between sluice valve and gate valve?
Gate Valves are by far the most widely used in industrial piping. The difference between Sluice Valves and Gate Valve is that the Gate Valves are generally used for water or water like fluids, while a Sluice Valve is recommended for Slurries. Type of Valves: Non Rising Spindle and OS&Y Rising Spindle.
