The TDV-100 Timed Discharge Valve – opens a solenoid valve at fixed intervals to dose a preset volume of water. Developed in collaboration with public health engineers, the TDV-100 helps minimise stagnation of water and the associated public health risks due to Legionella.
As well as protection against Legionella, other applications include refreshing deadlegs in unoccupied parts of buildings and to replenish seals in traps, gullies and drains compensating for loss of water due to evaporation etc.
The TDV-100 control is supplied ready wired and is simple to install and setup with clearly marked controls to set the necessary parameters.
If you have a specific requirement for the prevention of Legionella, we are able to provide solutions such as timed flushing of pipework or dumping of tank water stored above critical temperatures using our LP-10 Legionella Protect control. Please contact our technical department on 01603 720999 who will be pleased to discuss your requirements.
PRODUCT CODE: TDV-100-1/2″
Specification for TDV-100 Timed Discharge Valve
Dosing Volume / Interval: as both the ON (valve opening time) and the OFF (interval) is user adjustable from 0.1 seconds to 100 hours, it follows that almost any requirement can easily be fulfilled.
