The reverse-acting TV/SC-IR (Tube Valve/Instrument Enclosure) is designed to open on rising temperature to regulate the flow of cooling media to an enclosure. The thermal wax actuator end of the valve is installed into the wall of the instrument enclosure to continuously sense the ambient temperature within the enclosure. When the temperature rises above the valve's set-point, it will automatically modulate open to allow the injection of the cooling media. The valve will modulate closed again once the ambient temperature is within 10°F (5.6°C) of the open set-point. These economical valves are available with set points from 40°F to 210°F (4.4°C to 98.9°C).
The reverse-acting TV/SC-IR can regulate the flow of glycol, water, air or other cooling media to keep an enclosure cool via a vortex cooler to protect expensive analyzers and instrumentation from overheating.
