Automatic Air Release Valve -- Single Chamber Cast Iron

Single-chamber automatic air release valves for water distribution pipelines, pump stations, and elevated tank outlets. A lightweight polyethylene or stainless steel float rises with water level to close a small orifice, trapping pressurised air in the chamber. When air accumulates, the float drops and vents air automatically, preventing air locking, flow restriction, and water hammer. Cast iron body with epoxy coating for buried or exposed water service.
