Summary
Watts Industries Ultramix Trubert Eurotherm TX1REN Reverse Thermostatic Cartridge
The Watts Industries Ultramix Trubert Eurotherm TX1REN is a reverse thermostatic cartridge for TX91 Ultramix thermostatic mixing valves where the valve installation requires the reverse cartridge arrangement.
This cartridge controls the blended water temperature inside the mixing valve and is used to restore thermostatic temperature regulation when the original cartridge is scaled, worn, sticking or no longer maintaining a stable outlet temperature.
