Operation

As the fluid temperature increases to within the operating range of the TV/HAT-RA, the thermal actuator modulates the valve open. If the fluid temperature is above the acceptable range, the valve will continue to modulate open allowing additional fluid discharge. As the outlet temperature falls, the valve then modulates toward the closed position, reducing flow. This modulating action maintains a relatively constant outlet fluid temperature.

Applications

The TV/HAT-RA reverse acting valve may be used to regulate the flow of cooling water, glycol or other cooling media in applications requiring economical removal of heat from equipment or a process. Since the TV/HAT-RA valves open on rising temperatures, they can be used in many thermal relief valve applications.
