Engineering Notes:
- Series 13 Limitation: Not recommended for >120°C service or DN≥500 valves
- Galvanic Protection: Use dielectric kits when connecting to carbon steel piping
- Disc Maintenance: Field-polish with 400-grit max to preserve corrosion resistance
- Seat Replacement: Requires valve removal – Series 14 allows in-line servicing
GARANTIE:
SAVVY VALVES streeft naar uitzonderlijke productkwaliteit en zorgeloze aftersalesservice. Onze kleppen hebben een gegarandeerde minimale levensduur van 12 maanden. Gedurende deze periode leveren wij alle benodigde reserveonderdelen en gedetailleerde onderhoudsinstructies gratis. Mocht er binnen de garantieperiode schade ontstaan die niet door mensen is veroorzaakt, dan vervangen wij kosteloos de onderdelen en bieden wij professionele technische ondersteuning. Na de garantieperiode hoeven klanten alleen de kosten van de reserveonderdelen te betalen en profiteren zij nog steeds van kortingen op onderhoudsdiensten. Ons doel is om klanten te helpen de operationele kosten te verlagen en de productie-efficiëntie te verbeteren door middel van betrouwbare kwaliteit en uitgebreide aftersalesservice. Of het nu gaat om technische vragen of onderhoudsbehoeften, ons deskundige team reageert snel om ervoor te zorgen dat uw klepsysteem te allen tijde optimaal blijft presteren.
