The injection nozzles for chlorine are appropriately
combined fittings via which the chlorine solution (hypochloric
acid) supplied by the full-vacuum chlorinators is introduced
into the water to be treated.
The injection nozzle assembly comprises an injection

valve and a non-return valve.
The shutoff valve allows to separate the metering system
