Summary
Product Overview
This half turn 1/2 inch BSP flow cartridge with 20 splines is a generic ceramic flow control cartridge used in a wide range of tap and valve applications where a half turn on off action is required. It is designed as a service replacement to restore smooth operation and reliable shut off.
Function and Operation
The cartridge operates on a half turn ceramic disc mechanism which provides precise flow control and a positive shut off. Ceramic disc technology offers high resistance to wear and limescale build up, helping to prevent dripping taps and stiff operation over time.
Application and Servicing
This cartridge is typically replaced when a tap becomes difficult to turn, fails to shut off fully, or begins to drip. Correct sizing including 1/2 inch BSP thread and 20 spline handle interface must be confirmed before installation.
