ABSTRACT:
A two-way flow valve includes a valve body having a cavity and a stem longitudinally moveable therein which establishes two separate fluid flow paths through the cavity in the body from first and second inlet ports to a common outlet port. A spring biases the stem to a first position in which fluid flow is allowed along a first one of the paths and obstructed along the other. When a closure is applied to the valve, the stem is moved against the spring bias to a second position in which fluid flow is allowed along a second one of the paths and obstructed along the first path.
