FAQ
- A temperature regulator is a self-operated valve that holds a process at a target temperature without any external power or signal. A sensing bulb feels the process temperature, transmits the signal via capillary tube to a thermal actuator, and the actuator moves the valve open or closed to maintain setpoint. The plumbing equivalent of a thermostat: simple, reliable, no electronics, no operator input.
- Use the self-operated regulator when the duty isn't critical, when there's no power at the install location, when you want fewer things to break, or when the cost of a full instrumented loop isn't justified. Common on equipment cooling, glycol systems, storage tank temperature maintenance, and steam-heated jacketed vessels. Use an electronic control loop when you need tight accuracy, remote setpoint, alarms, trend data, or integration with the DCS.
