Titanium Alloy Globe Valve DN80 Price – Specialized for Marine Engineering
1. Titanium Alloy Globe Valve DN80 Price Reference
Currently, the market price of a titanium alloy globe valve DN80 generally ranges from 1,800 to 4,500 RMB per unit, depending on titanium grade (TA1/TA2/TC4), manufacturing process, pressure rating, and brand:
Economy models (TA2 pure titanium, manual operation): approx. 1,800–2,800 RMB
Mid-to-high end models (TC4 titanium alloy, worm gear or pneumatic actuator): approx. 3,200–4,500 RMB
Marine engineering has strict material requirements. It is recommended to prioritize titanium grades of TA2 or above to avoid pitting or crevice corrosion caused by inferior materials.The main stop valve product names of China Stop Valve Network include:Flange Straight-through Low Temperature Globe Valve,Flange Fluorine-lined Globe Valve,Forged Steel Straight-through Globe Valve,GB Stainless Steel Flange Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Oxygen-specific Globe Valve,Vacuum Isolated Straight-through Globe Valve,Y-type Rubber-lined, Fluorine-lined Globe Valve.
2. Why Is It Specialized for Marine Engineering?
Seawater corrosion resistance – Titanium alloy forms a dense oxide film on its surface, offering resistance to chloride ion corrosion far superior to stainless steel and copper alloys.
High strength, low density – Excellent specific strength reduces the dead weight of piping systems, making it suitable for space-constrained applications such as offshore platforms.
Reliable sealing – Hard seal or PTFE soft seal structures maintain zero leakage under alternating high and low temperature conditions.
Long service life, maintenance-free – Service life can exceed 20 years in marine environments, significantly reducing replacement frequency and maintenance costs.
3. Purchasing Suggestions
When evaluating the price of titanium alloy globe valve DN80, it is recommended to also confirm:
Titanium material certificate (including third-party composition test report)
Pressure rating (PN16 / PN25 / Class 150)
Classification society certification (CCS, ABS, DNV, etc.)
Conclusion: Although the price of titanium alloy globe valve DN80 is higher than ordinary valves, its corrosion resistance and reliability in marine engineering offer significant advantages, making it an economically sound choice for long-term operation.
