Eclipse F Adaptative Flow Control Thermostatic Radiator Valves Thermostatic radiator valve with automatic flow limitation
IMI HEIMEIER / Thermostatic Heads & Radiator Valves / Eclipse F Eclipse F The thermostatic radiator valve Eclipse has a unique integrated flow limiter that eliminate over flows. The required flow rate can be adjusted directly at the valve with a twist. The adjusted flow will not be exceed even if there are load changes in the system, due to other valves closing or during morning start up. The valve controls the flow rate independently from differential pressure. Therefore, complicated calculations to determine settings are not necessary. Key features > > Integrated flow limiter Eliminates over flows > > Easy adjustment Just a twist to reach design flow > > Flow range from 0 to 0 l/h For high flexibility > > All valve bodies with II+ marking can be retrofitted as Eclipse i.e. Calypso exact, Calypso, Mikrotherm F, Multilux, Multilux -Set > > Perfect for renovation Standard dimensions and easy flow sizing Technical description Applications area: Heating systems.

Flow setting Replaceable insert The complete thermostatic insert can be replaced using the fitting tool without draining the system. Function Eclipse flow limiter A regulating part is set to the calculated control rate by turning the digit cap with the setting key or an mm end wrench. If the flow rate increases at the valve the rising pressure moves the sleeve, thus constantly limiting the flow to the set value. The set flow rate is therefore never exceeded. If the flow rate drops below the set value a spring presses the sleeve back to its original position. Application The thermostatic radiator valve Eclipse is applied in two-pipe pumped heating system with normal to high temperature spread. The required design flow for each radiator is set directly on the Eclipse valve. This automatic flow limitation is done with a twist and the adjusted flow will then not be exceeded. Even if there is an oversupply of pressure, due to load changes in the system, for example other valves closing or during morning start up, Eclipse will guarantee the requested flow. The valve controls the flow rate independently from differential pressure. Therefore, complicated calculations to determine settings are not necessary. The pressure loss of pipings in old systems does not have to be determined in renovation projects. Only the heating capacity and the resulting max. flow rate have to be determined (see setting chart). The min. differential pressure has to be at the most unfavourable valve. If necessary, it can be measured in order to optimize pump settings (see accessories). Renovation All IMI Heimeier thermostatic radiator valves with II+ marking, i.e. Calypso exact, Calypso, Mikrotherm F, Multilux, Multilux -Set can be retrofitted as Eclipse. Noise behaviour To ensure low-noise performance, the following conditions must be met: The differential pressure above Eclipse should not exceed 60 kpa = 600 mbar = 0,6 bar (<0 db(a)). Flow must be correctly adjusted. The system must be completely deaerated.
IMI HEIMEIER / Thermostatic Heads & Radiator Valves / Eclipse F Sample application. Eclipse. Lockshield Regulux/Regutec. STA balancing valve for maintenance and diagnostics. Boiler Notes To avoid damage and the formation of scale deposit in the hot water heating system, the composition of the heat transfer medium should be in accordance with the VI guideline 0. For industrial and long-distance energy systems, see the applicable codes VdTÜV and 66/AGFW FW 0. A heat transfer medium containing mineral oils, or any type of lubricant containing mineral oil can have extremely negative effects and usually lead to the disintegration of EPM seals. When using nitrite-free frost and corrosion resistance solutions with an ethylene glycol base, pay close attention to the details outlined in the manufacturers documentation, particularly concerning concentration and specific additives. Flush the system before changing thermostatic valves in heavy polluted existing systems. The thermostatic valve bodies can be used with all IMI Heimeier thermostatic heads and IMI Heimeier or IMI TA thermal or motorized actuators. The optimal tuning of the components guarantees maximum safety. When using actuators from other manufacturers, make sure that the pressure power is appropriate for thermostatic valve bodies with soft sealing valve discs. Operation Flow setting Stepless setting between to (0 to 0 l/h). The setting is changed using a special setting key (article No. 90-0.) or an mm end wrench, to ensure tamper proof setting. Place the setting key on the valve insert. Turn the setting tool so that desired setting value is pointing at the index* of the valve body (see fig.). Remove the key or mm end wrench. The valve is now set. Front-end and lateral visibility *) SW *) Index
