GENERAL
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 cataloged
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 heat 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.
