Product Description
The V2471 Verafix-VK is a radiator connection valve for 2- pipe heating systems, where compact radiators with a builtin thermostatic insert and a 50 mm-gage bottom connection are used. It features Resideo's Verafix insert, which enables the regulation of the kv-value and shut-off using an allen key. It also enables radiator draining and filling, facilitated by an adapter, and fail-safe resealing after the draining operation using the brass cap with secondary PTFE sealing ring. It is available in angled (wall connection) and straight (floor connection) patterns, with the following radiator connection options:
- Y15: For radiators with a G3/4" Euroconus connection per EN 16313, and via a reducing nipple for radiators with a G1/2" internal thread
- X20: For radiators with a G3/4" external thread and flat seal, and using a sealing conus for radiators with a G3/4" Euroconus connection according to EN 16313
On the pipe side, V2471 Verafix-VK has a G3/4" Euroconus interface.
