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.

Valve Rotation
• The pulses of the valve coil cause the magnet
to rotate inside the valve body.
• As the magnet rotates, it moves the cam at
the bottom of the valve.
