The TV/HAT-RA-LP is an in-line, self-operating temperature control valve designed to regulate coolant flow by modulating open on rising temperatures, maintaining a constant outlet temperature without external power. It features a stainless steel body, fittings, spring, and ram-type plug, with a compact, low-mass design for fast thermal response. The valve includes a leak port to sense upstream temperature changes during startup and operates within a narrow temperature band. It supports maximum operating pressures of 150 PSIG (10 bar) and temperatures up to 300°F (149°C). Available in 3/8" and 1/2" tube sizes with EPDM or Viton seals, it is suitable for cooling water applications in compressors, engines, heat exchangers, welding, electrical, and molding equipment.
The TV/HAT-RA-LP is installed on the cooling water outlet of the equipment as an after flow controller. At start-up, the valve is closed except for the “control leakage”, allowing a small amount of flow to 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, the valve then modulates toward the closed position, reducing flow. This modulating action maintains a relatively constant outlet water temperature.
TV/HAT-RA-LP valves are ideal for controlling cooling water for compressors, engines, heat exchangers, welding equipment, electrical equipment, and molding equipment.
