ASV valves are designed to be used in
HVAC circulating systems to control
differential pressure in risers or in every
terminal unit.
To limit the flow for every circuit, the
ASV-I with its pre-setting capability
should be used together with constant
pressure control provided by an
ASV-PV, providing a balanced
distribution in the system.
