![<!--<$[標(biāo)題]>begin-->CO2 Check Valve<!--<$[標(biāo)題]>end-->](/picture/0/cf636702884947b0b461a662a2605370.png)
CO2 check valves control the forward and reverse flow of refrigerant and make refrigerant flow in a specified direction and ensures normal operation under high working pressure in the CO2 transcritical system.
FEATURES
? Stainless steel housing ensures reliable operation under maximum high pressure of 45MPa
? Soft sealing structure, low internal leakage
? Built-in sliding piston design enables valve-opening under low differential pressure
? Elastic adjustment parts allow installation in any position
? Standardization design, compact size
OPERATION CONDITIONS
? Applicable Refrigerants：R744（CO2）
? Maximum Working Pressure：15MPa
? Medium Temperature：-30℃~ +120℃
? Ambient Temperature：-30℃~ +55℃
? Relative Humidity: below 9506
