Altecnic Ball Valve 3/8 F/F Red Lever AI-171R03

The Altecnic 3/8 F/F Ball Valve with Red Lever Handle is a quarter-turn isolation valve for boiler and heating pipework. It has female threaded connections at both ends and a red lever handle for open/closed operation. The lever gives a clear visual indication of valve position, making it straightforward to isolate a section of the system during service or repair.

• The spindle or gland weeps when the lever is turned
• The lever is stiff, seized or will not turn through its full quarter-turn travel
• Drips appear at the body or threaded connections while the valve is closed
• Scale, corrosion or staining is visible around the body or spindle
• Isolation fails — flow continues through the valve when it is shut

• Confirm the 3/8 in female-to-female connections match the pipework or fittings being isolated
• Check there is space for the red lever handle to swing through its full travel
• Confirm the valve suits the system pressure and temperature it will be exposed to
• Match the Altecnic product code AI-171R03 if replacing an existing valve of the same type
