Danfoss 003N-6252 1/2″ 70-140°F Close on Rise Temperature Regulating Valve

Description

The Danfoss 003N-6252 is a self-actuated temperature regulating valve designed for precise fluid temperature control in hydronic and HVAC systems. With a 1/2″ connection size and a 70–140°F operating range, this valve operates on a close-on-rise principle — automatically closing as the sensed temperature increases — providing reliable, power-free regulation without the need for external controllers or actuators.

Built to Danfoss’s exacting engineering standards, this temperature regulating valve is ideal for applications where consistent thermal management is critical, including heating systems, heat exchangers, and process cooling circuits.
