USV

USV-I / USV-M

USV valves are designed for manual hydronic balancing of heating and cooling systems.

USV-I (red knob) is used together with USV-M to limit the flow in heating or cooling installation or can work separately as manual balancing valves for flow limitation. If certain pipe sectors do not require a control of differental pressure, USV-I and USV-M can be used as shut-off- and measuring valve.

USV-M (blue knob) valve can be upgraded intoan automatic USV-PV balancing valve. USV-M isdesigned for installation in the return pipe.

Upgrading from manual to automatic balancingis done by mounting PV-controller to an USV-M valve.

System does not need to be depressurized during the upgrade and the kV-values does notchange. USV-PV maintains constant differentialpressure across a riser.

Due to its special design USV-PV has a firm connection between diaphragm housing and valve cone.

USV-S

USV-S valves are designed for manual hydronic balancing of heating and cooling systems.

USV-S (black knob) is used to limit the flow in heating or cooling installation or can work separately as manual balancing valves for flow limitation.

USV-S is compact valves in which the operating elements and connections are placed within an arc of 90°, so that in spite of small valve dimensions, access for installation and operationis optimal.
