Protect your irrigation system from air locks and vacuum damage. Our automatic air release valve exhausts trapped air during system filling and draws air in during drainage – preventing pipe collapse from vacuum negative pressure. Available in 1/2" to 2" sizes with male thread connections, working pressure range 0.1-10 bar. The float mechanism operates automatically – no manual intervention needed. Composite gas dynamics design ensures rapid intake and exhaust with excellent low-pressure sealing. Install at pipeline high points, pump outlets, and filter stations. ISO PN10 rated. UV stabilized engineering plastic construction.
