## Long description

Subminimal blue flow controller insert is a compact replacement insert designed to regulate fluid flow in compatible valves and fittings. The insert provides a consistent restricted flow to help maintain stable flow rates in plumbing and technical systems. Intended as a service or spare part, this regulating flow insert is suitable for maintaining existing systems where controlled limiting of fluid volume is required.
Advantages
The Subminimal blue flow controller insert delivers reliable flow restriction in a small form factor, enabling precise control of fluid passage without major modifications to existing fittings. Its compact design simplifies installation and replacement, reducing downtime during maintenance. The insert is manufactured to fit compatible valves and provides predictable hydraulic behaviour, supporting stable operation of downstream components.
Suitable for
Plumbing systems requiring limited or metered flow
Technical installations where stable, reduced flow is needed
Service and maintenance of compatible valves and fittings
Replacement of worn or missing flow-regulating inserts
Key specifications
Function: fixed flow regulation / flow restriction
Colour: blue (identifies regulator type)
Form factor: compact insert for valve/fitting integration
Material: engineered plastics and/or corrosion-resistant components suitable for fluid contact (as used in standard flow inserts)
Application environment: cold and warm water systems and other compatible non-aggressive fluids
How to use
Turn off system supply and relieve pressure before removing the existing insert or opening the valve. Extract the old insert according to the valve manufacturer’s service instructions, then insert the Subminimal blue flow controller insert until it seats fully in the fitting. Reassemble the valve or fitting and restore supply, checking for leaks and verifying the resulting flow rate meets system requirements. If necessary, test the system at normal operating pressure and adjust other control components to accommodate the regulated flow.
Usage recommendations
Use this insert only in valves and fittings specified by the valve manufacturer as compatible with restrictor inserts. Verify fluid compatibility and operating pressure limits before installation. Replace damaged or clogged inserts promptly to maintain consistent flow control and avoid downstream performance issues.
