This extremely useful motorised valve actuator enables every room to be controlled automatically at any pre-set temperature.

Ideal for schools, colleges, hotels and residential buildings where individual control over separate areas is needed, this maintenance-free unit enables heating to be controlled on an individual room-by-room basis.

For greatest flexibility, the PRE9501 should be fitted in conjunction with Prefect Irus mains borne signalling system, or with any of the ecostat2 series of discreet local switches. The unit enables entire radiator systems to be programmed automatically, all from a PC anywhere in the building (when used with Prefect Irus).

The PRE9501 valve actuator fits to the head of a standard TRV Valve body via the M30x1.5 connection ring. the valve drive utilises a thermal drive wax motor, a small amount of wax is heated which then expands with force, this is then applied to the TRV, opening the valve silently and efficiently. since there are no mechanical parts the drive is very robust and reliable whilst being cost effective.
