FlowCon A, AB and ABV Dynamic Balancing Valve with Adjustable Flow Insert The FlowCon A, AB and ABV automatic balancing valves are designed for balancing heating and airconditioning terminal units by providing a constant flow rate with the added feature of being adjustable. With these automatic balancing valves flow can be controlled with one of two different inserts; either an internal composite insert or an externally adjustable E-JUST insert. Both insert-types keep the flow rate constant, even with system pressure conditions changing. The main difference between these and other automatic balancing valves is that each flow control insert can be easily adjusted to a new flow rate if necessary. Standard Composite Insert The standard composite insert is easily removed from the valve body and adjusted to one of eight different flow rates by means of an Hex key. There are 14 different adjustable inserts, totalling nearly 100 different flow rates available for valve sizes 15mm through 40mm. E-JUST Insert The E-JUST insert can be externally adjusted to one of 41 flow rates even when the system is operating. The E-JUST insert is tamper-proof since adjustment is carried out by means of a special FlowCon key. Further the setting can be sealed with a top cover. Stainless Steel Insert Alternatively, a factory pre-set stainless steel insert can be used together with an adaptor. These inserts are single flow inserts, but exchanging of the insert and adaptor is straight forward. Features and Benefits - Automatic balancing, the correct flow rate for each circuit is achieved automatically. - Dynamic balancing, the correct flow rate is maintained as each valve compensates for pressure fluctuations in the system. - Field adjustable, flow rate can be changed on demand, either internally or externally adjustment or insert exchange. - Elimination of branch or ’’partner’’ balancing valves which results in fewer total valves used in each project. - Easily accessible insert for flow rate adjustment or maintenance. - Accuracy of ±10% or 20 l/hr (standard composite insert) alternatively ±5% of controlled flow rate or ±2% of maximum flow rate (E-JUST insert). For stainless steel inserts accuracy is ±5%. - Built-in isolation ball valve (FlowCon ABV). - Pressure/temperature measurement plugs available for verifying operating differential pressure or checking ΔT across the coil (FlowCon AB/ABV). - Double union end connection for ease of installation and wide selection of end fittings (FlowCon ABV) or fixed female threaded ends (FlowCon A/AB).
