Air Release Valve (ss304, 25 mm)

Air Release valves are fitted on the topmost points of Dry Risers, their main purpose being to release the air when water is pumped into the Riser. A floating ball arrangement inside the valve housing allows air to be released, but blocks the outlet when water reaches the valve, allowing pressure to build up in the Riser.

Air Release Valve, made of Stainless Steel (SS304), 25 mm size MBSP threaded Inlet. The valve housing shall incorporate suitable arrangement (with ball) to release air from the riser when being filled with water, but close the opening when water reaches the valve.
