Claim 18:
19. A method of reducing fluid consumption in an electronic device manufacturing system, comprising:
flowing a fluid through a temperature actuated valve positioned in a fluid line of the electronic device manufacturing system, the temperature actuated valve comprising:
a stationary member and a movable member disposed within a housing, wherein the stationary member is configured to receive the movable member;
a first annular flow path defined between an outer surface of the stationary member and an inner surface of the housing;
a second flow path defined by and within the movable member;
at least one temperature actuated member comprising a first end seated against a base of the stationary member and a second end seated against a base of the movable member, wherein the at least one temperature actuated member comprises a shape memory alloy; and
a bias member comprising a first end connected to the base of the stationary member and a second end connected to the base of the movable member; and

opening and closing the temperature actuated valve based on a temperature of the fluid, wherein the at least one temperature actuated member is configured to compress causing the valve to reduce an opening to the second flow path when the fluid is at a first temperature and expand causing the valve to at least partially open to increase an opening to the second flow path when the fluid is at a second temperature.
