**Production Introduction**
The manifold end components are manufactured using a forging process. This automatic air vent valve is designed to continuously remove air and water from the system during operation. It also has the function of water injection pressure testing during commissioning and drainage during maintenance. The check valve provides a shut-off function, ensuring that the system remains operational even when the automatic vent is replaced, thus reducing energy consumption.
These valves are commonly used in heating systems such as radiators, underfloor heating, and boiler systems. They are typically installed at the highest point of the system or directly connected to the manifold and radiator. Their main purpose is to expel internal air so that the radiator can be fully filled with warm water, ensuring consistent room temperature.
