Abstract: Non-magnetic thermally-controlled bimetal valves comprising active and passive members having different coefficients of thermal expansion, and systems incorporating such valves, are described herein. These valves and systems find particular application in the field of patient care as it relates to magnetic resonance (“MR”) environments, such as environments with strong electromagnetic fields generated by MR imaging machines.
