Domestic Plumbing & Heating

The 520 adjustable thermostatic mixing valves is designed to maintain the preset temperature of the mixed water delivered to the user despite variations in the temperature of the water contained in the system.

The 520 is ideally suitable of use on underfloor heating to maintain the circulating water through the underfloor coil at the preset temperature, by mixing hot water from the boiler with the return water from the coil.

The Classic thermostatic radiator valve, lockshield valve and radiator vent are of
durable construction giving dependable performance for building services and domestic
applications.
The chrome finish of the valves is ideal for designer interiors, period decors or
restoration projects.

The CALEFFI XF filter separates impurities in the system right from the first passage. Its large filtration surface and impurity separation upstream of the filter also minimises the problem of mesh clogging.

System water is treated in three distinct steps: an initial separation mesh, a central magnet and an outlet filter.

CALEFFI XF continuously protects the generator and devices from any impurities that form in the hydraulic circuit. It can be adjusted for horizontal or vertical installation.

Internal cleaning brushes mean that maintenance can be carried out without shutting off the device.
