The TV/SC-I assures accurate temperature control in an instrument or analyzer enclosure. It’s a reliable, economical alternative to costly, hazardous electric heating. This self-contained compact thermostatic control valve senses enclosure temperature and automatically regulates the flow of steam or other heating medium to maintain the specified temperature. In cooling applications the reverse-acting TV/SC-IR can be used to regulate the flow of glycol, water, air or other cooling media.
A thermostatic element located at one end of the TV/SC-I (inside the enclosure-see line drawing) regulates the steam supply to the heater to accurately maintain the desired temperature, operating like a thermostat in an oven. Heat radiating from the steam coil heater reaches the actuator causing it to quickly shut off the steam supply when the desired temperature is reached, regardless of outside ambient. In cooling applications, the TV/SC-IR opens on rising temperature to regulate the flow of cooling media to the enclosure. These economical valves are available with set points from 40°F to 210°F (4.4°C to 98.9°C).
