The TV/HAT/RA-LP continually senses fluid temperature and automatically modulates to maintain desired temperature. Optimum operating temperature improves system efficiency, reduces wear and conserves energy. ThermOmegaTech valves are designed around our exclusive Thermoloid® sensor/controller which is the most advanced and reliable thermal actuator of its type available today. All ThermOmegaTech valves are factory tested and calibrated to assure unsurpassed accuracy, reliability and quality.
The TV/HAT-RA-LP is installed on the cooling water outlet of the equipment as an afterflow controller. At start-up, the valve is closed except for the “control leakage”, which allows a small amount of flow so that the actuator inside the valve can sense the changing equipment temperature. As the outlet water temperature increases to within the operating range of the TV/HAT-RA-LP, the thermal actuator modulates the valve open. If the cooling water temperature is above the acceptable range, the valve will continue to modulate open allowing additional cooling flow. As the outlet water temperature falls slightly, the valve then modulates toward the closed position, reducing flow. This modulating action maintains a relatively constant outlet water temperature even as the cooling load changes.
TV/HAT-RA-LP valves are perfect to control cooling water for compressors, engines, heat exchangers, welding equipment, electrical equipment, molding equipment, pump bearings. The TV/HAT-RA-LP continually senses cooling water outlet temperature and automatically modulates to maintain desired temperature. Optimum equipment temperature improves efficiency, reduces wear and conserves cooling water.
