Abstract: A valve is provided for controlling the flow of fluid through a valve block. The valve block has a fluid inlet port, a fluid outlet port, and a receiving bore for receiving the valve. The receiving bore hydraulically connects the fluid inlet and outlet ports, and has a central axis. The valve comprises a valve seat for placement between the fluid inlet and outlet ports, wherein the valve seat comprises a central axis which coincides with the central axis of the receiving bore, and wherein the valve seat further comprises an upper end overmolded by a valve seat attachment end of a plastic valve housing. The valve also includes a tube which comprises a central axis which coincides with the central axis of the receiving bore, wherein the tube further comprises a lower end overmolded by a tube attachment end of the valve housing.
