- Narrow operating temperature band - Compact low mass - fast response - Ram-type plug for reliable shut off - Unaffected by pressure variations - Quick, easy installation - Compatible with standard tubing and connections - Long service life (36 month pro rated warranty) - Direct acting (no pilot valve) - 100% factory tested

Advantages: At any chosen set point from 30°F (-1.1°C) to 170°F (77°C), these valves can economically automate a system in response to ambient temperature. (For higher temperatures, consult factory.) Tubing connections allow quick installation at low cost. These valves reduce waste, lower maintenance cost, are economical to operate and save space.

Applications: There are literally hundreds of applications for these compact, self-contained, automatic control valves. Ambient sensing valves can be used to turn on steam, air, gas or liquids compatible with Teflon® and stainless steel, in response to ambient temperature change. Applications include automation of steam trace lines, operation of pneumatically operated pumps for injection of antifreeze liquids, instrument enclosure control, etc. TV/SC-AR (reverse-acting) can be used to regulate the flow of glycol, water, or other cooling media or can automate cooling sprinklers, cooling baths, etc.

Operation: At the designated set point, a thermostatic element located at one end of the valve (and thermally isolated from the body of the valve), will open or close within a 10°F (5.6°C) differential (e.g. 35-45°F, etc.) and control the flow of steam, gas, or fluid through the valve based on ambient temperature. The TV/SC-A opens on falling temperature; the TV/SC-AR opens on rising temperature. An optional solar shield (when used) allows the device to be installed where solar heating may affect the set point of the device. The TV/SC-A may also be used to control instrument enclosure temperatures (see TV/SC-I and ITCH product fact sheets).
