AAV-16T Brass Vacuum Breaking Valve is mainly used in container or pipeline, when the pipeline or container produces negative pressure or vacuum gradually rises due to system operation or stop, the valve can open automatically to destroy the vacuum effect, so that the pipeline and other equipment will not produce deflated, concave cracks and other phenomena, in order to protect the safety of the equipment. It is used in the fields of water supply and drainage, dockyard, power plant, metallurgy, shipbuilding, etc. It can meet the needs of various working conditions.
Product Features
- High operational safety and reliability. Under positive pressure conditions, it maintains excellent sealing without leakage. Under negative pressure conditions, the cover plate operates flexibly, enabling rapid and substantial air replenishment.
- Operates fully automatically without manual control, utilizing atmospheric pressure as its power source, requiring no external power supply.
- Installation is simple and requires no debugging. Simply follow the instructions to install correctly for normal operation.
