Function: This valve facilitates the flow of hot water into or out of the radiator, allowing for manual isolation or flow control.
Configuration: The design shown is typically used in a "straight" or "angled" configuration depending on how the pipe exits the floor or wall.
Connection: It features threaded ports for secure connections to both the supply/return pipes and the radiator tailpiece.
Role in Heating Systems
Balancing the System: By adjusting the valve, you can control the heat output of individual radiators to ensure even heating across different rooms.
Maintenance: They allow for the isolation of a single radiator so it can be removed for repairs or decorating without needing to drain the entire central heating system.
