A thermostatic element located at one end of the TV/SC-I (inside the enclosure) regulates the steam supply to the heater to accurately maintain the desired temperature, operating like the thermostat in an oven. Heat radiating from the steam coil heater reaches the actuator causing it to quickly shut of the steam supply when the desired temperature is reached, regardless of outside ambient. The TV/SC-I comes complete with a weather-tight bulkhead fitting for the valve body; optional bulkhead fittings for 3/8 tubing connections are available. Also available is a short configuration for installations with the valve and all connections completely within the enclosure (see TV/SC-A and ITCH product fact sheets). These economical valves are available with set points from 35°F to 200°F (1.7°C to 93.3°C)
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 compact thermostatic control valve senses enclosure temperature and automatically regulates the low of steam to maintain the temperature. In cooling applications the reverse-acting TV/SC-IR can be used to regulate the low of glycol, water, air or other cooling media.
