Danfoss Balancing Valves

Danfoss balancing valves make sure each heating or cooling circuit receives its design flow, so flats near the plant room do not overheat while distant ones stay cold. This page covers Danfoss automatic (dynamic) differential pressure controllers, their partner valves, static (manual) balancing valves and the AB-PM combination.

How to choose a Danfoss balancing valve

First decide whether the system has variable flow (radiators with thermostatic valves, motorised valves) or constant flow. Variable-flow systems need ASV-PV or AB-PM to keep the differential pressure automatically; static valves suit constant-flow circuits where a one-off setting is enough.

Browse all brands in balancing valves, or the sub-groups dynamic and static balancing valves. Popular items: the ASV-PV DN15–DN50 differential pressure controller and the LENO MSV-BD static balancing valve. More on the Danfoss brand page.

All products are original and supplied with an invoice; the warranty is provided by the manufacturer or importer. The current price is shown on each product card: the VAT-inclusive price first, the VAT-exclusive price below it.

Frequently asked questions

Static or dynamic balancing valve?

A static valve is set once by hand and creates a fixed resistance. A dynamic valve keeps the differential pressure or flow at the set value automatically as the load changes.

How is ASV-PV connected?

ASV-PV is installed in the return pipe and linked to the partner valve on the supply (ASV-I, ASV-D or ASV-BD) by a 1.5 m impulse tube. The DN15–DN50 model is adjustable between 20 and 60 kPa.
