46-5 N - Differential pressure and flow limiter - for installation in return flow pipe

The Type 46-5 N Regulators are self-operated proportional regulators for heating systems. They are used to keep differential pressure at the set point of 0.2, 0.3, or 0.5 bar, and to limit the flow rate to a value within a range between 0.2 and 1 m³/h (standard version) or 0.12 and 0.5 m³/h (special version), adjustable at the restriction.

The regulators restrict the flow rate to ensure it does not exceed a certain level. The integrated set point spring determines the differential pressure created at the restriction required to limit the flow rate as well as the differential pressure set point.
