Robertshaw Industrial Products is now Schneider ElectricEffective January 1, 2017, the name of the legal entity, Invensys Systems, Inc., dba Robertshaw Industrial Products, will change to Schneider Electric Systems USA, Inc. This is part of the continued integration of Invensys into Schneider Electric. See Notice

The RT-1004-Al series is a non-indicating design suited to heating and cooling applications. The narrow throttling band means that the RT-1004-A1 series is very sensitive to temperature changes at the large sensing bulb. It is particularly applicable where the storage capacity of medium to be heated is great while the heating surface is relatively small. The extra large bellows develops power for more positive action on higher pressure drops on valve sizes bove two inches.

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 sensingbulb 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.
