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
