Abstract

See full text

A valve includes a valve housing defining a fluid flowpath therethrough, a valve element located in the valve housing and movable in the fluid flowpath to regulate a fluid flow therethrough, and a valve actuator operably connected to the valve element to urge movement of the valve element in the fluid flowpath. The valve actuator includes an actuator housing, a volume of paraffin located in the housing, and an actuator rod located in the actuator housing and operably connected to the valve element, such that phase change of the paraffin urges movement of the actuator rod between a first position and a second position, thereby moving the valve element between a retracted position and an extended position.
