The IMI Heimeier Eclipse TRV radiator pack, consists of an automatic flow control TRV body, DX head and lockshield. Designed for application in a two-pipe pumped heating system. 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 desired flow. The thermostatic head with our incompressible liquid-filled sensor guarantees a reliable and precise room temperature control.
Max. working temperature: 120°C, with protection cap or actuator 100°C.
