AM1 Regulating Main valve DN20-100

Technical parameters

• Nominal pressure: 2.8MPa
• Applicable temperature:-50℃ ~+120°c
• Test pressure:4.2MPa
• Applicable medium: ammonia, fluorine, propane,etc.

Characteristics

• Flow regulating valves, servo-operated by different pilot valves screwed-in the main valve or mounted in an external pilot line.
• The AM1 are designed to use with ammonia and other common fluorinated refrigerants,for liquid,suction，discharge or defrosting lines, and they have one port, thus, you can screw-in one pilot valve only.
• The thread to screw-in the pilot valves is M24x1.5,and the pressure gauge connection 1/4″BSP.
• The degree of opening of AM1 valves is function of the differential pressure between the inlet and outlet,so if the pressure difference is Ap = 0.3 bar, the main valve will be fully open, and if it is ap = 0.2~0.3 bar, the degree of opening will be correspondingly proportional to Ap.
