Abstract
A thermal isolator assembly that provides rigid construction, linearly and rotationally, is presented. The thermal isolator assembly includes a collar and a sleeve that are thermally isolated one from another but held in rigid mechanical relation. When constructed for actuated valves, the collar forms an actuator arm coupling member while the sleeve forms a valve stem coupling member. A pair of thermal isolators provide thermal isolation between these members. A polyphenylene sulfide compound, and preferably a fiberglass reinforced polyphenylene sulfide compound is used because of its high mechanical strength and low thermal conductivity for these thermal isolators.
