  1. Critical Notes & Selection Tips
  1. “Bronze Seated” Definition:
  • This data sheet reflects a true Bronze-to-Bronze seal. The wedge has a Bronze ring/face that mates with the Bronze seat in the body.
  • Torque Requirement (Mandatory Gearbox):
    • For a DN500 PN10 metal-seated valve, a gearbox (worm gear) is NOT optional – it is mandatory. The solid wedge and metal-to-metal contact create very high seating and unseating torque. Please confirm the gearbox ratio with the supplier.
  • Leakage Rate:
    • Metal-seated valves cannot achieve “zero leakage” (bubble tight) like resilient-seated valves. They typically conform to ISO 5208 Rate D (0.1x DN mm³/s) or Rate E. Please confirm the acceptable leakage rate for your application.
  • DIN 3352 Structure:
    • DIN 3352 is a multi-part standard. Your valve most likely conforms to DIN 3352 Part 4 or Part 5 for cast iron gate valves, or a specific metal-seated variant.

    Action Required:
    Please confirm with the manufacturer:

    1. Gearbox Ratio & Output Torque (Is it suitable for manual operation under max differential pressure?)
    2. Sealing Leakage Rate (ISO 5208 Rate D or better?)
    3. Flange drilling details (DIN 2501 PN10) to match your pipeline.

    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.
