Commonly used with mixing valve thermostat (MPPT-C) to mix cold water returning from UFH circuits with boiler water to achieve lower underfloor temperature. Often attached to a remote pump module in current systems, or within pipework leading between the boiler and underfloor circuits in earlier manifold and zone valve systems.
Allows full flow of water through the valve
