Altecnic Calflow Plus 15mm 10 Litres/Min Flow Regulator (Blue) AI-81121510

The Calflow Plus is a flow regulation device manufactured by Altecnic, supplied in a 15mm size with a rated flow of 10 litres per minute and blue identification. It is used to control and stabilise the flow rate through a heating or water system, keeping draw-off conditions consistent at the outlet. The blue variant denotes its position within the Calflow Plus flow rate range.

• Flow rate at the outlet is noticeably higher or lower than the rated 10 litres per minute, with no change to system settings.
• Draw-off performance varies between outlets or fluctuates during use, suggesting the regulator is no longer holding a steady flow.
• Noise or vibration at the valve during draw-off, which can indicate internal wear or debris in the regulating element.
• Water temperature at the outlet becomes unstable because the flow rate passing through the regulator is inconsistent.
• Visible scale, debris or damage at the valve body or connection after servicing or a system flush.

• Confirm the connection size required is 15mm.
• Confirm the required flow rate is 10 litres per minute for the application.
• Check the colour identification of the existing unit, as the Calflow Plus range uses colour to distinguish flow rates.
• Verify the appliance family listed in the fitment information matches the installation.
