127 sanhuaeurope.com YCVS-R SERIES Piston type check valves are designed for installation in commercial refrigerating systems and in residential or industrial air conditioning plants. They are used to control the unidirectional flowof refrigerant to prevent backflow. The Design Pressure (PS) of the versions YCVS-R equal to 49 bars and the internal structure able to resist to refrigerant temperatures until +150°C, making them suitable for R32 systems without liquid injection and high discharge temperatures.
