Without need for external power, Robertshaw Self-Actuated Temperature Regulators (SATR) offer final control of the temperature of a liquid, an air space or flow, or gas flow for domestic, equipment, process, space, etc. on heating or cooling service.
The SATR sensing bulb is installed in the medium being controlled while the SATR valve is located on the supply line of the medium used as the heating (steam, hot water) or cooling (water, ethylene glycol, brine) agent. The SATR regulates the heating or cooling medium flow to maintain the desired temperature at the sensing bulb location. Robertshaw SATR are usually cataloged to detail the two-way direct acting (close on temperature rise) type valves for heating service. Two-way reverse-acting (open on temperature rise) and three-way valves are equally available for cooling service.
The Robertshaw SATR series offers a selection of: Throttling bands, Temperature Indication, Fail-safe to prevent overheating, Manual Positioning in addition to automatic control, Corrosive atmosphere resistant type, Small overall size and instantaneous beat exchanger service.
Most cataloged Robertshaw SATR specifications are starting points from which many alternates to cataloged capillary, sensing bulb, separable well and valve may be FURNISHED TO MEET YOUR SPECIFIC application's needs.
The RT-1006-A1 Series
The RT-1006-BI series is a non-indicating design suited to heating or cooling applications where temperature overheating is of basic concern. This series is designed and constructed to push the stem downward in the event of a loss of thermal charge. It will close a direct-acting valve or open a reverseacting, on charge lost, to prevent the overheating associated with other temperature regulators. For larger valves, greater valve stroke or higher pressure drops see the RT-1007-Al series.
The RT-1007-A1 Series
The RT-1007-Al series is a non-indicating design suited to heating or cooling applications where temperature overheating is of basic concern. This series is designed and constructed to push the stem downward in the event of a loss of thermal charge. It will close a direct-acting valve or open a reverse-acting valve, on charge loss, to prevent the overheating associated with other temperature regulators. The RT-1007-Al series can be supplied with small valve sizes; however, the more economical RT-1006-BI is normally used with the advantage of smaller bulb size, etc
