POA Valves

POA Valve Types

Pilot Operated Absolute (POA) Valves are the Suction Valves that were used on most mid 60's to mid 70's GM vehicle air conditioning systems and on some 70's Ford systems.

Suction Valves

"Suction Valves are air conditioning valves mounted to the Evaporator's suction (top) outlet to regulate air conditioning system pressures and prevent the Evaporator from freezing".
