Bronze valves
Leveraging 12 Years of Naval Bronze Valve Expertise to Deliver Reliability in Shipbuilding Systems
Made with continuous-cast C95800 marine bronze, our valves withstand 25MPa pressure and 200°C steam. The patented triple-seal design with graphite-reinforced packing and laser-welded seats ensures zero leakage through 100,000+ cycles. DNV-GL/ISO 15848-1 FT2 certified, each component endures 5,000-hour salt spray testing—equivalent to 20 years offshore.

ISO 9001/TS 22163 Certified Factory
  • How do you prove your valves can withstand long-term seawater corrosion?
    We conduct triple verification:
    ① 5,000-hour salt spray test under DNVGL-CP-0091 standard (equivalent to 20 years of service)
    ② Intergranular corrosion report of C95800 alloy from a third-party laboratory
    ③ Cathodic protection compatibility certificate from Norwegian classification society
  • What is the shortest delivery cycle for urgent orders?

    For DNV standard valves:
    48-hour express delivery: 2,000 sets of maritime-grade stock at the Wales bonded warehouse
    72-hour custom production: Flexible production line + laser additive manufacturing emergency channel

  • What is your cost advantage compared to European and American brands?
    We achieve a 30% cost optimization through vertical integration:
    In-house C95800 alloy smelting workshop (no middleman markup)
    Fully automated gravity casting line (qualification rate 98.7% vs industry average 92%)
    Ningbo/Liverpool dual bonded warehouses (reduces 25% in logistics and customs duties)
  • How do you handle sudden leakage issues?
    Our global warranty mechanism includes:
    ① Emergency service team arriving at the site within 48 hours
    ② Priority allocation of replacement valves (faulty parts must be retained)
    ③ Root cause analysis report (provided within 10 working days)
