Abstract
A valve assembly is provided that is suitable for use as an air release valve. The valve mechanism is actuated by liquid forced through an orifice by a diaphragm under pressure from the main discharge and is less prone to valve chatter under varying pressure conditions. The use of an externally adjustable orifice and/or regulator allows the valve assembly to operate satisfactorily in a wide range of pressures. The mode of operation of the valve mechanism is externally visible.
