Titanium Butterfly Valve for Corrosive Process Systems<\/h2>\n

\u8be5 WDL Titanium Butterfly Valve<\/strong> is designed for flow isolation
\nand control in systems where conventional stainless steel valves may suffer
\nfrom pitting, crevice corrosion or rapid material loss. Titanium develops a
\nstable protective oxide film that can reform after minor surface damage when
\nsufficient oxygen or another oxidizing agent is present.<\/p>\n

WDL supplies titanium butterfly valves in wafer, lugged and double-flanged
\nconfigurations. Available designs include concentric soft-seated valves,
\nhigh-performance double-offset valves and triple-offset metal-seated valves.
\nThe final construction is selected according to the fluid composition,
\nconcentration, operating temperature, pressure, required shutoff class and
\nfrequency of operation.<\/p>\n<\/section>\n

\n

Why Is Titanium Used for Butterfly Valves?<\/h2>\n

Titanium combines low density with useful mechanical strength and strong
\nresistance to many chloride-bearing and oxidizing media. This makes a
\ntitanium butterfly valve suitable for seawater, brine, desalination and
\nselected chemical processes where corrosion allowance alone cannot provide
\nan acceptable service life.<\/p>\n

    \n
  • Strong resistance to seawater and many chloride-bearing solutions<\/li>\n
  • Lower weight than many nickel-based corrosion-resistant alloys<\/li>\n
  • Protective oxide film with self-passivating behavior<\/li>\n
  • Good strength-to-weight ratio for large valve discs<\/li>\n
  • Smooth wetted surfaces that can reduce product adhesion<\/li>\n
  • Available for soft-seated and metal-seated valve designs<\/li>\n
  • Suitable for manual, pneumatic and electric actuation<\/li>\n<\/ul>\n<\/section>\n
    \n

    Available Titanium Grades<\/h2>\n

    WDL can manufacture wetted components from titanium Grades 2, 3, 5, 7 and
    \n12. The grade should not be selected by pressure rating alone. Chemical
    \ncomposition, chloride level, pH, temperature, flow velocity and possible
    \ncrevice conditions must also be reviewed.<\/p>\n

    Applications of Titanium Butterfly Valves<\/h2>\n

    Titanium butterfly valves are commonly selected for industrial systems
    \nexposed to chlorides, seawater or oxidizing chemicals. WDL reviews the
    \ncomplete operating data before confirming the titanium grade, seat material
    \nand valve design.<\/p>\n

      Important Media Selection Notes<\/h2>\n

      Titanium is not universally resistant to every acid or chemical. Dry
      \nchlorine, strongly reducing acids and media with insufficient oxidizing
      \nconditions require a separate corrosion review. Slurry service also
      \nrequires evaluation of particle size, solids concentration, velocity and
      \nabrasion because corrosion resistance does not automatically provide
      \nresistance to erosion.<\/p>\n

      For accurate valve selection, provide the medium composition,
      \nconcentration, operating and design temperatures, operating and design
      \npressures, pipeline size, flange standard, required shutoff performance

      Which titanium grade is normally used for a butterfly valve?<\/h3>\n

      Grade 2 is a common starting point for seawater, brine and many oxidizing
      \nmedia. Grade 7 or Grade 12 may be considered when the process has more
      \ndemanding acidic, thermal or crevice-corrosion conditions.<\/p>\n

      Can WDL supply wafer and lugged titanium butterfly valves?<\/h3>\n

      Yes. WDL can supply wafer, lugged and double-flanged titanium butterfly
      \nvalves. The connection type is selected according to the pipeline standard,
      \nmaintenance requirements and whether downstream pipe isolation is required.<\/p>\n

      Can a titanium butterfly valve be used for slurry?<\/h3>\n

      A titanium butterfly valve can be considered for corrosive slurry, but the
      \ndisc, seat and flow velocity must be reviewed for erosion. Titanium solves
      \ncorrosion problems but may require additional seat or trim protection in
      \nhighly abrasive service.<\/p>\n

      What information is required for a quotation?<\/h3>\n

      Please provide the valve size, pressure class, medium composition,
      \nconcentration, temperature, flange standard, seat requirement, actuator
      \ntype and quantity. WDL will evaluate the material and configuration before
      \npreparing the quotation.<\/p>\n<\/section>\n
