Invensys (ACL Drayton) Cyltrol Valves

Still one of the most economical methods of effectively limiting the temperature of domestic hot water in older systems with limited control, Cyltrol is available in 1" BSP for gravity circulated systems.

Installed in the primary return, no more than 0.3m from the cylinder, Cyltrol senses return water temperature and varies the primary flow until the desired domestic hot water temperature is reached. At this point it will shut off the primary flow, ensuring that hot water does not reach dangerously high levels, thereby offering protection particularly to the young and elderly.
