DXF系列膜片式單向閥采用濾網、磁鐵、膜片自吸結構設計，從而使單向閥不受安裝角度限制和反向壓力大小的關系影響閥門的自動閉合，具有極小的流通阻力、流量大、內泄漏量幾乎為零等特點，使空調能效比大有提高，使用壽命1000萬次以上。該閥適用于制冷劑和大中型冷熱空調系統。為保證產品正常閉合，內置濾網30目。
DXF series diaphragm type check valve with self suction filter structure design,magnet,diaphragm,so that the valve can beautomatically closed relationship between valve installation size and angle limit reverse pressure,with small flow resistance,large flow,internal leakage is almost zero,and other characteristics,the energy efficiency is better than that.The service lifeof more than 10 million times.The valve is suitable for all refrigerants and large and medium sized cold and hot airconditioning systems.In order to ensure the normal closure of the product,the built-in filter screen is 30 mesh.
