IMI Eclipse 15mm Angled TRV & Lockshield Pack (9690-61.800)

IMI Hydronic's Eclipse thermostatic radiator valve 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. IMI Hydronic's 15mm Eclipse Thermostatic Radiator Valve with Automatic Flow Control (AFC), Thermostatic Head & 15mm Lockshield Valve. IMI Hydronic's patented TRV design speeds up system commissioning by allowing each radiator to be 'set' to the correct flow rate within 10 seconds.
