Description
Combination air release valve made from robust ductile iron, designed to efficiently expel trapped air and prevent vacuum formation in pipeline systems. Automatically vents air during filling and operation while allowing air intake during drainage or pressure drops to maintain system stability. Rated PN16 for pressures up to 16 bar, suitable for medium-pressure water and industrial applications. Threaded ends provide secure, leak-tight connections for straightforward installation and maintenance.
