Description
Combination air release valve constructed from durable ductile iron, designed to efficiently release trapped air and prevent vacuum conditions in pipeline systems. Ensures smooth flow and protects system integrity by automatically venting air during filling and operation, and admitting air during drainage or pressure drops. Rated PN16 for pressures up to 16 bar, suitable for medium-pressure water and industrial pipelines. Equipped with flanged ends for secure, leak-proof connections, allowing easy installation and maintenance.
