Product DescriptionProduct DescriptionPrecautions for the Use of Automatic Air Release Valves The performance of an automatic air release valve relies on "correct model selection, installation, and maintenance". Improper operation may lead to exhaust failure, liquid leakage, or component damage. The following 6 key points require special attention:1. Model Selection: Match System Parameters to Avoid "Undercapacity"Pressure Matching: The "nominal pressure (PN)" of the air release valve must be ≥ the system's operating pressure. For example, a heating system typically uses a valve with PN 1.0-PN 1.6 MPa, while a high-pressure industrial pipeline requires one with PN 4.0 MPa or higher. Otherwise, high-pressure liquid may push open the valve core, causing leakage.Caliber Matching: Select the caliber based on the pipeline diameter and air displacement. For instance, DN 15-DN 25 is commonly used for household/small-scale systems, and DN 50 or larger may be required for industrial systems. An undersized caliber will result in slow exhaust speed, failing to discharge air in a timely manner.Material Matching: Choose the valve body material according to the corrosiveness of the fluid. For ordinary water systems, brass or cast iron can be selected; for corrosive fluids (such as chemical liquids), stainless steel (304/316L) or plastic (PPR) should be used.SIZELHWEIGHT/KGDN1579120.195DN2079150.235DN2579160.29
