The Danfoss 003L8152 impulse tube is an original accessory designed for ASV series differential pressure controllers. The tube transmits the pressure signal between the differential pressure controller (ASV-P, ASV-PV) and its partner valve (ASV-I, ASV-M or ASV-BD), thereby enabling the correct operation of dynamic hydronic balancing in heating or cooling systems.

The 1.5 m length covers standard installation distances in residential and commercial systems. The package includes O-rings for a tight and reliable connection at both ends of the tube. The impulse tube must be flushed before installation.

The tube is also a standard part of the package for ASV-P and ASV-PV valves (DN 15–40), where it allows the assembly to be connected immediately after installation without the need to order additional accessories. For greater installation distances, 2.5 m (003Z0690) and 5 m (003L8153) versions are available.
