USV-S valves are to be used in radiator heating systems to limit the flow in risers or horizontal loops. 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 operatingelements and connections are placed withinan arc of 90°, so that in spite of small valvedimensions, access for installation and operationis optimal. Insulation caps for temperature up to80 oC or 120 oC are available as accessory.USV-S is supplied in a set-pack with internal thread.
USV-S can also be used in floor heating systems.To limit the flow, every manifold with constantflow should be used together with USV-S valves.
The USV-S valves are to be used in systems withfan coils to limit the flow in order to provide efficient heat distribution
