Ball valve / Burn-back protection -Smart (XS)-

The ball valve serves to prevent burn-back and must always close tightly.
If scoring, adhesions or damage are visible, the ball valve must be replaced urgently.

We strongly recommend replacing the sealing ring as well.

For ÖkoFEN Smart or Smart XS pellet boilers of the following years of manufacture:

• Smart model year from 07/2016
• Smart XS all model years
  

If you need the ball valve for a Smart with a different model year, please send us an email with a photo of the type plate of your boiler.

The ball valve is supplied with a sealed guide and shaft.

We strongly recommend replacing the sealing ring as well.
