Isenberg TVH™ Series Thermostatic Control Valves
Constant Water Temperature
Another great feature of the thermostatic valve is that once the temperature knob is set – it will output water at a fixed temperature (within a range of usually 2° Celsius).
Just turn the volume control know on and off and leave the temperature knob as is. And you will have the same temperature every time (within 2° Celsius).
Control Water Volume – Full Force Down To A Trickle
All Isenberg thermostatic valves control the volume of water via a separate volume control knob. The water volume can be controlled specifically from full flow down (13PGM in our case) down to Zero GPM.
This way the user can have a flow and volume of water as per their wish. Maybe have full flow when you are rinsing your hair to get the shampoo out and a slower flow otherwise.
Servicing Your Shower Valve
Servicing thermostatic valves is important and quite easy. The thermostatic valve has within it a thermostatic cartridge which has a wax element. The wax comes in contact with hot and cold water and expands and contracts.
This expansion and contraction regulates the temperature of water by allowing only a certain amount of hot and cold water through the cartridge. The cartridge also has rubber o-rings which provide watertight seals. Those should always be checked for damage.

Checking The Thermostatic Shower Cartridge
Once your cartridges have been removed it is important to visually inspect them for defects.
– Check for dirt
– Clean filters
– Inspect o-rings
– Inspect rubber seals
If any of these parts especially o-rings and rubber seals are damaged they need to be replaced.
