Radiators turning off method
Radiators and convectors will most often be fitted with a Hand Wheel Valve. This valve allows the radiator to be isolated from the heating circuit from which it derives its supply. The hand wheel valve is essentially and on-off device. It has a very limited capacity to regulate the water flow, so it is used fundamentally to switch off a radiator in a location when heating is not required.

A Lock Shield Valve will also be installed on each radiator.

A 21 return rad valve

This valve is used by the installer to balance the flow of water to each radiator. The valve must be operated using a screwdriver or special tool and is therefore not intended to be adjusted by the householder.
