Threaded End Single Ball Air Vent

This air vent, featuring a single ball, small volume, light weight, and small exhaust flow, is installed at the highest point of the sewage pipeline or where air is trapped to release sewage pipe gas, ensuring smooth pipeline operation. In case of power failure, pump stoppage, or accidental breaks, negative pressure may form inside the pipeline. The exhaust valve and air suction valve then quickly draw in air, safeguarding the pipeline from damage.
