Air release valve

Features

lInlet and exhaust air valves are suitable for various irrigation system applications. When the system is filled with water, the air valve discharges a large amount of air in the pipeline; when the system is emptied, the air valve draws in a large amount of air to prevent vacuum negative pressure.

lThe valve adopts advanced composite gas dynamics design, with rapid intake and exhaust; it can avoid air accumulation, prevent the formation of negative pressure, and has good sealing performance at low pressure.

Product Usage

lIrrigation system pipe network: Exhaust the air in the irrigation system to avoid negative pressure on the downstream of the pumpandthe wateralong the pipeline andup-down slope of the pipeline.

lIrrigation First part: Discharge air to prevent negative pressure at the filter and fertiliser tank.

lIrrigation pipeline High place: Exhaust air to avoid air accumulation at high points in the system to damage the pipe.
