Summary
The Vola VR1477 / VR1477K thermostatic cartridge is a replacement thermostatic cartridge for VOLA FS3 mixer valves. It is used inside the FS3 thermostatic shower mixer to regulate blended outlet temperature and help restore stable temperature control where the existing cartridge has become worn, scaled or difficult to calibrate.
This part is listed with the Vola VR1477 reference and the Hastings-Vola VR1477K cartridge reference for FS3. Check the code on the existing cartridge where possible before ordering, especially on later FS3 installations where the cartridge reference may differ.
