Mixer/header kit
The fixed-position mixer kit (which can be converted to a variable position), is used to mix hot water from the boiler with water flowing back from the circuits for a stable delivery temperature.The kit is supplied with a 3-flow rate circulation pump for secondary fluid, making it highly versatile and suitable for all types of systems, from the smallest to the largest. The Valsir header has a number of benefits, first and foremost the “memory” of the holders.After the system has been balanced, the maximum opening of the holders can be set, so they can be used as cut-off valves for circuit flow.The special feature of this system is that the holder can be reopened to the number of revolutions corresponding to the balancing value.Another important aspect is that Valsir headers have an automatic air bleed unit, with blowdown valve on both the delivery and return headers.
