Self-Contained Thermal Actuator
The heart of the F Series valve is a unique, solid-liquid phase thermal actuator. This hydrocarbon wax-filled device actuates the valve in response to changes in temperature. The transition from solid to liquid phase causes a large change in volume, exerting a tremendous force over a narrow temperature band.
