How It Works . . .
All PE reversing valves, 2-way, 3way, or 4-way, work on the same basic principles. They function to cause a positive change in the direction of refrigerant flow within the system. The pin guided interchange spool opens or shuts discharge and suction ports through direction of pressure differentials between high and the low side of the system. The reversing valve consists of the main body, a pilot solenoid valve body, and a special PE coil. Many valves in field service have been cycled over 1,000,000 times without malfunction.
