A self actuating valve (10) including a housing (12) and a flow control member (14), and magnetic material (16, 17) integral with the housing (12) and the flow control member (14), respectively, with at least one of the magnetic material (16, 17) being permanently magnetized. The housing (12) includes a flow control chamber (18) and first, second, and third ports (20, 22, 24) connected to the chamber (18). The flow control member (14) is mounted in the chamber (18) for movement between first and second positions. In the first position, the member (14) blocks flow between the first and second ports (20, 22), blocks flow between the first and third ports (20, 24) and allows flow between the second and third ports (22, 24). In the second position, the member (14) allows flow between the first and second ports (20, 22) and blocks flow to the third port (24) from both the first port (20) and the second port (22). The magnetic material (16, 17) generates a magnetic force between the housing (12) and the flow control member (14) that is greater with the flow control member (14) in the first position than with the flow control member (14) in the second position.
