ABSTRACT:
A refrigeration isolation valve including an integral pair of ball valves closed coupled by a custom union for disconnecting and replacing charged refrigeration components. The annular bore through the valve bodies and coupling are consistent with the ball valve aperture. The external diameter of the valve body and coupling are also consistent. The isolation valve is further fitted with a vent for purging trapped air and refrigerant. A method is taught for isolating and disconnecting essential refrigerant components from a system and replacing such components with a precharged component without disturbing the system integrity.
