Description
The Spence Engineering OYE-20-CP (SKU 169032) is a self-operated temperature regulator engineered for precise, reliable temperature control in steam and hydronic HVAC systems. Part of Spence’s trusted OYE series, this unit requires no external power source — it uses the energy of the controlled medium itself to modulate flow and maintain set-point temperatures with accuracy and consistency.
With a compact 7×11×2 body profile and ODF (Outside Diameter Flare) connections, this regulator is designed for straightforward field installation in a variety of commercial and industrial piping configurations. The 10-foot capillary tube provides flexible remote sensing capability, allowing the sensing bulb to be positioned precisely where temperature measurement is needed most.
