The TDV-100 Timed Discharge Water Valve
The TDV-100 Timed Discharge Water 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 water valve helps minimise stagnation of water and the associated public health risks due to Legionella and Legionnaires Disease
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 water valve control is supplied ready wired and is simple to install and setup with clearly marked controls to set the necessary parameters. A ‘Plug and Play’ solution.
We’ll even set the ON and OFF times for you if you wish – saving you valuable time on site!
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.
Specification for TDV-100 Timed Discharge Water 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.
