![<!--<$[标题]>begin-->FDM Series Diaphragm Check Valves<!--<$[标题]>end-->](/picture/0/95a4a1077c064825971e29de53f494d7.jpg)
FDM Series diaphragm check valves are widely used in VRVs, commercial air conditioners, heat pump hot water heaters, and commercial refrigeration. They are used to control the unidirectional flow of refrigerant so as to prevent backflow.
FEATURES
• This valve can ensure the only correct flow direction to prevent back flow
• Filter screen installed at the inlet of this valve to effectively filter impurities
• Magnetic vale plate design without installation angles limits
• Red copper valve body without any solder joints ensures no leakage
OPERATION CONDITIONS
• Applicable Refrigerants: R410A, R32, R134a, R404A, R507, R290, R407C and R22 (For R290, please confirm before placing orders.)
• Maximum Working Pressure：4.5MPa
• Medium Temperature： -30℃~ +120℃
• Ambient Temperature：-30℃~ +55℃
• Relative Humidity: below 95%
