Flova FH 619-84 Levo SMBOX-UN Thermostatic Cartridge Handle (Pura / Levo Range)
This FH 619-84 thermostatic cartridge handle is a 40 mm component designed for use with the Flova Levo SmartBOX-UNI concealed thermostatic valve system. It replaces the original handle and cartridge assembly when maintenance or replacement is required.
Function
The cartridge handle allows precise thermostatic control and safe temperature regulation in Levo shower or bath/shower valve assemblies fitted with SlimBOX-UNI rough-in modules. It controls hot and cold water balance, enabling thermostatic shut-off and consistent water temperature even under changing supply conditions.
Confirmed Compatible Valve Systems
Before purchasing, verify your valve uses the SmartBOX-UNI rough-in module and the existing handle or cartridge matches part code FH 619-84. Cartridges and handles are not universal across all Flova or Pura valve families.
Selection and Verification
Check your leak-down diagram, installation documentation or existing handle code to confirm FH 619-84 is correct for your valve. Because Flova uses multiple thermostatic cartridge configurations across different valve ranges, correct match of model and rough-in module is essential.
When Replacement May Be Required
Replace the handle and cartridge if temperature regulation becomes unreliable, shower water does not remain stable under pressure fluctuations, thermostat adjustment becomes stiff or erratic or if the existing handle is damaged or worn. Fitting a correct FH 619-84 handle can restore proper thermostatic control without replacing the valve body.
