Abstract
A valve apparatus for distributing flow from an inlet among either of two outlets consists of essentially four components comprising a valve body, a second valve seat, a poppet assembly, and an actuator assembly. The valve body comprises an inlet port and two outlet ports disposed between a top end and a bottom end of the body. The inlet and outlet ports communicate with a centrally located valve chamber. A first valve seat is integral with the body and is disposed in the chamber between the inlet port and the second outlet port. A second valve seat is formed separately from the body and is disposed within the chamber between the inlet port and the first outlet port. A poppet assembly is disposed within the chamber and comprises an enlarged diameter section integral with a valve stem positioned between opposing top and bottom ends of the stem. The enlarged diameter section comprises an upper shoulder adjacent the second valve seat and a lower shoulder adjacent the first valve seat. A diaphragm is integral with the stem and positioned at the top end of the body. Actuating means displace the poppet assembly between a first position and second position within the valve chamber effecting flow to the first and second outlets, respectively.
