Description
The Sterling-Sterlco D151.02.0000 is a 3/4″ direct-acting (D/A) temperature regulator engineered for precise, dependable temperature control in hydronic and steam heating systems. Featuring a remote sensing bulb connected via a 6-foot capillary tube, this regulator responds directly to system temperature changes — opening or closing in proportion to the sensed temperature to maintain consistent setpoint conditions.
Key Features
- 3/4″ valve body connection for easy integration into standard piping configurations
- Direct-acting (D/A) operation — valve opens as temperature rises, providing straightforward and reliable modulation
- Temperature control range of 85–125°F, suitable for a wide variety of heating and process applications
- 6-foot capillary tube allows remote bulb placement away from the valve body for accurate sensing at the point of control
- Self-contained thermostatic design — no external power source required
- Durable construction built to meet the demands of commercial and industrial HVAC and steam system environments
Typical Applications
- Hydronic heating systems requiring zone or circuit temperature regulation
- Steam heating systems with temperature-sensitive control requirements
- Process heating and industrial fluid temperature management
- Boiler and heat exchanger outlet temperature control
