ABSTRACT:
A multiple port refrigeration circuit valve uses a valve head mounted upon a threaded stem to selectively control fluid flow through the valve. While the valve housing is formed of a plurality of parts assembled by heating the construction of the valve head permits an elastomeric seal to be used in combination with metal seal surfaces, and the use of the elastomer eliminates leakage and reduces the torque required to form an effective seal.
