Repair package needs improving
Valve is fine, but it really should come with a set of 3 screws as I had to use the old ones. Also the rubber washers are also not the right size. I had to use the old ones too. It works fine now.

Not so good after warranty
Don’t bother if you want to replace it after 14 months, yes, 2 months after warranty expired. I called seller but did not help, no regret….

Very Similar
Very similar to original Vaillant valve. Be careful to place pump connection in first as tends to drip from there if align with heat exchanger plate first.

Corps de V3V déformé
La face d'étanchéité coté échangeur est déformée, j'ai été obligé de réutilisé l'ancien corps et de remonter les éléments neufs (cartouche et moteur). Je ne recommande pas l'achat de cette pièce chez ce fournisseur, le prix semble intéressant, mais la qualité n'est pas bonne.
