Al-Ni-Co has the advantages of not being easy to rust, strong suction, etc., which ensures the longer service life of the magnetic check valve, even if the magnetic check valve is installed at an uneven level. In the refrigeration pipeline, the diaphragm can also be firmly adsorbed to ensure the tightness of the Miracle refrigeration check valve.
Refrigeration Check Valve uses a Composite Diaphragm Design
Miracle refrigeration check valve uses a diaphragm made of high-quality rubber and magnetic steel. The composite refrigeration check valve has the advantages of high-temperature resistance and various refrigerants.
