Taille :

From 0,5 to 15 l/s

Application :

Limitation of rainwater flows downstream of the retention basins, valleys, hydraulic structures

Conception :

• Stainless steel vortex with a minimum quality of 304 L on support plate made of very thick PEHD
• Nominal diameter from 30 to 180 mm

Fonctionnement :

Tangentially supplying a circular chamber creates, through the increase in upstream pressure, a vortex current with the formation of an air core at the centre of it. The simple effect of the current allows for the limitation. The vortex effect limiter behaves as a hydraulic resistance and makes it possible to increase the reliability of the limiting system by a large passage section that is always constant.

Options :

• Adaptation plate for connection to higher DN - ADAPTPVX
• Prefabricated manhole made of composite polyester with a built-in PVX flow limiter - REGARDPVX
