· In heating and domestic hot water systems, for temperature
control in hot water storage heaters.
· In radiant panel and radiator systems, if you want to:
- control the temperature in the single rooms heated by the circuits
branching out from the manifold.
- shut off each circuit directly at the manifold, with less labour and
cost for making the electric connections.
·
In fan-coil systems, if they are to be fitted with valves for automatic
shut-off of the medium.
·
In zone systems, where reduced dimensions and limited flow rate
coefficient at the automatic regulating valve are required.
