A flow regulator is a device used to control the flow rate of liquids or gases in a system. It ensures that the fluid moves at a consistent speed, preventing fluctuations that could cause damage or inefficiency. Flow regulators are commonly found in various applications, including plumbing, irrigation, and industrial processes. These devices can be mechanical or electronic, and they often work by adjusting the size of the opening through which the fluid passes. By maintaining a steady flow, regulators help improve system performance and conserve resources, making them essential in systems like water supply and HVAC (heating, ventilation, and air conditioning).
