3-Way Valve Body
• The valve body contains a cam, rotor and
magnet.
• The rotor and cam are grooved to rotate with
the magnet.
• The entire valve body has refrigerant fl owing
through it when the compressor is operating.
• Use care not to damage the top of the valve
body when installing the coil on the valve.
• A locating pin is used to correctly align the
valve body in the valve coil.
• Failure to fully seat the valve in the coil or to
align it correctly with the pin can cause the
system to stop cooling.
