Flow Regulating Discs

Flow regulating discs can be easily fitted to any existing tap or shower head to reduce the amount of water flowing from the outlet without adversely affecting the outlet pressure.

On average 22L of water flows from a household tap every minute. HydroSave Flow Regulating Discs are designed to reduce outlet flow to 6, 9, or 12 litres per minute, a saving of up to 75% dependent on the application. Flow through Flow Regulating Discs is primarily controlled by the use of a fixed orifice principle. However the HydroSave flow regulating disc also provides dynamic flow control properties through the use of an O-Ring insert.

Under low flow conditions the O-Ring remains relaxed and provides a fixed orifice dimension. As flow increases the O-Ring reacts against the flow by unseating and slowly reducing the flow capacity of the orifice until the maximum restriction is achieved.
