Summary
Ultramix Trubert Eurotherm TX537 Thermostatic Cartridge (TX95E37, TX95C37) - Flow Rate (Litres Per Minute): Minimum 5 - Maximum 260
The Ultramix Trubert Eurotherm TX537 is a replacement thermostatic cartridge for selected Watts ULTRAMIX TX95 high productivity thermostatic mixing valves using the 30 to 70 C cartridge specification. The Di Vapor part number is ET-TX537 and the manufacturer reference identified for this cartridge is 22TX537.
This thermostatic mechanism controls mixed water temperature inside the valve and is used where stable blended-water output is required across high-flow communal or multi-outlet installations. It is the 30 to 70 C version and should not be confused with the TX5 10 to 50 C cartridge used in other TX95 valve versions.
