Ambient Temperature Control

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.



Therm-O-Mix® Station w/Brazed-Plate Heat Exchanger

When the shower or eyewash is activated, the pressure drop on a diaphragm opens the steam control valve (V-3). Water and steam flow are established instantly heating the water and condensing the steam. A mixing valve (V-1) then blends the heated water with cold water to produce an output of 85°F water. Additional valves keep the system preheated, freeze protected and scald protected. Steam valve remains closed should water supply be interrupted.



Instrument & Analyzer Protection


TV/SC-I valves (top left) will maintain enclosure temperature accurately over a wide range of ambient temperatures with steam supply pressures from 15 psig to 200 psig (1.0 to 13.8 BAR) without danger of overheating delicate instruments. No special NEMA-7 or -9 housings are required even in potentially explosive environments. Other direct and reverse acting models are available.
