What Is Venturi Valves？
Venturi valves are specialized flow control devices designed to regulate fluid or gas flow by utilizing the Venturi effect. In essence, they feature a constricted section that creates a pressure drop, allowing for precise control of flow rates. These valves are widely used in various industries and applications, including HVAC systems, industrial processes, and pneumatic systems, to ensure efficient and optimized flow control.
How Does Venturi Valves work?
Venturi valves operate based on the Venturi effect, which involves fluid passing through a constricted section. As fluid flows through the narrowed portion of the valve, its velocity increases while its pressure decreases. This pressure drop allows for precise control of flow rates, making Venturi valves effective in regulating fluid or gas flow in various systems.
