Hydronic systems use various valves, primarily for controlling, regulating, and directing water flow. Common types include balancing valves for flow regulation, control valves like characterized ball, globe, and butterfly valves for system adjustment, pressure-independent control valves (PICVs) for constant flow despite pressure changes, and specialized valves such as check valves, diverter valves, and pressure relief valves.
A hydronic balancing valve is designed to adjust the flow rate in the pipes of a hydronic heating or cooling system to ensure even distribution of heat or chilled water throughout the system. Proper balancing is crucial for the efficiency and performance of a hydronic system, as it ensures that all areas receive the appropriate amount of heating or cooling. These valves are adjusted during system commissioning and may be readjusted if the system layout changes or if imbalances are detected during operation.
These devices introduce resistance to a section of the pipe, allowing technicians to fine-tune the flow rate for even temperature distribution.
Simple throttling devices that help to balance the system by controlling flow.
Automatically adjust to maintain constant flow rates, often using a combination of a control valve and a pressure regulator, according to red-white valve corp.
Pressure-Independent Control Valves (PICVs): More advanced control valves that maintain a constant flow rate to a coil or branch, regardless of changes in system pressure.
