Balance valves are often used in systems with multiple branches or zones, such as heating or cooling systems with multiple radiators or air conditioning units. By adjusting the flow rate in each branch or zone, balance valves ensure that each area receives the appropriate amount of fluid to maintain desired temperatures or pressures.
There are different types of balance valves, including manual balance valves that require manual adjustment, and automatic balance valves that adjust automatically based on changes in flow or pressure. Some balance valves also have additional features such as flow meters or pressure gauges to monitor and control the system more effectively.
