The core purpose of flow control valves is to maintain a constant fluid flow rate by automatically adjusting the valve opening, ensuring stable system operation even under pressure fluctuations. Main application areas include:
Building water supply systems: Used in parallel pipe networks for fire protection and domestic water supply, automatically distributing flow and preventing pressure fluctuations from affecting water supply stability.
Central heating/cooling systems: Solves hydraulic imbalance problems, distributes pipe network flow on demand, eliminates uneven heating and cooling, and saves 15%-20% on energy.
Industrial and automotive systems: Controls the movement speed of actuators (cylinders, motors) in hydraulic equipment (such as construction machinery).
Automotive steering systems limit the maximum flow rate of the hydraulic pump to avoid energy waste; refrigeration systems dynamically adjust refrigerant flow to prevent compressor damage.
