Val-Matic 38 air release valve is designed to release pockets of unwanted air in a pressurised water system to protect against air-related surges. It is widely used in water distribution & transmission fire pumps, pressure filters and hydropneumatic tools.

When water enters the air valve, the float rises because of buoyancy and seals the valve. As air accumulates in the valve body, the float drops and opens the valve's orifice to vent accumulated air or gas from the system.
Almost all types of liquids tend to carry deposits and suspended particles. To avoid possible functional disturbances and clogging caused by dirt, the valve has to be checked periodically and serviced (if needed).
Air pockets in pressure piping systems reduce the efficiency of the flow and increase the power required for pumping. If big air pockets are created, they may cause a pressure surge, pipe rupture or even damage.
