6v battery powered Timed Discharge Valve for regular periodic flushing of pipework to reduce stagnation and associated public health risks due to the Legionella bacteria. Removes human error risk associated with manual pipe flushing, ideal for remote sites where mains electricity is unavailable. The control is also suitable for replenishing trap seals due to evaporation.
The TDV-6v uses quartz crystal controlled timekeeping and low power technology giving an average battery life of 3 – 4 years! The control is easy to setup with a wide range of user selectable time intervals including hourly, 4 times daily, 2 times daily, daily, every two days, 2x weekly. The volume of water which is discharged or dumped is determined by the valve opening time. This can simply be set using the internal pushbutton or (without removing the front cover) using the Magi-Test wand. Hence the control may be configured to discharge any volume from a fraction of a litre per week to many litres per hour covering the vast majority of applications.
A low battery status warning is provided by the LED which blinks every 2 seconds.
We do however recommend a procedure put in place to change the batteries at least every 3 years.
