• SB150


    • Off-center split-body design allows the use of advanced spiral-wound gaskets.
    • Maximum temperature for CF8M 1,000°F (538°C), forWCB800°F(426°C).
    • Full port ensures large capacity and reduces the risk of clogging when handling solids or slurries.
    • Wall thickness complies with ASME B16.34 and BS 5351 for 2-12" ASME 150 and 300 full port only.
    • Stem bearing reduces side thrust effect on packing and prevents stem wobbling.
    • Integral seat locking option does not require additional parts or special tools.
    • Scraper seats standard.
    • Ball and seats lapped for optimum performance and tight shutoff.
    • Low emission stem seal.
    • Blowout-proof stem.
    • Two-piece flanged gland. Live-loaded as standard.
    • All valves with graphite packing and backup seal are inherently fire safe.
    • Can be used for manual throttling applications. (For automation contact Velan Engineering.)
    • Manual operation with handle for 2-4" (50-100 mm) FP and 3-6" (80-150 mm) RP. 6" (150 mm) FP, 8" (200 mm) RP and larger require gear or actuator. Gear or pneumatic actuator available.
    • Tightness rates: Allowable leakage rate at full Delta P: ASME/FCI 70-2 Class V. Tighter shutoff available upon request.
    • Oversized ball to stem connection provides:

    - No deformation of the stem slot in the ball.
    - Better throttling control performance.
    - Less motion loss and wear in automatic on-off applications.

  • UB-150


    • Exclusive Memoryseal™ seats compensate automatically for wear and fluctuations of pressure and temperature.
    • Unique 4-Way and 3-Way packing arrangements for superior stem sealing (refer to page 7 for details).
    • TA-Luft certified.
    • Multiple solid cup and cone type PTFE stem seal and graphite packing.
    • Stem guides prevent side thrust.
    • Long cycle life
    • Low, uniform torques.
    • Blowout-proof stem.
    • Fully enclosed PTFE body seal.
    • Metal-to-metal contact between insert and body act as secondary seal and prevents overcompression of the seats.
    • Pipe flange gasket acts as third precautionary seal as threads from the insert are within the raised face flange.
    • Meets worldwide specifications. Design ASME B16.34, BS 5351, API 608(2), fire tested to API 607 Rev. 4, BS 6755 and API 6FA. ISO/CAPI for all parameters of standardized valve automation.
    • Locking device standard for valves with lever handle.
    • Highest standards of quality.
      Over its 50 years of production activities Velan has earned a worldwide reputation for quality in design, manufacturing and valve performance.
    APPLICATIONS: These rugged, versatile, high performance ball valves meet requirements for oil and gas pipeline service and can meet NACE specifications when required.

    The valves can handle a vast variety of fluids, slurries, semi-solids and almost any corrosive service in chemical, petrochemical, oil, gas, pulp and paper, processing and other industries.

  • TypeT1


    • Permits in-line access for seat replacement.
    • Can be welded into line without disassembly. Consult IOM manual for details.
    • Full port reduces risk of clogging in slurries and solids applications.
    • Body-cover joint not affected by pipe stresses.
    • High sealing integrity of body-cover joint due to fully-enclosed spiral-wound stainless steel graphite gasket design.
    • Solid Stellite 6 seats with large seating faces.
    • Backup seal: Graphite to 1,000°F (538°C).
    • Operation automatically wipes ball clean.
    • Wall thickness complies with ASME B16.34.
    • Stainless steel ball, hard chrome plated.
    • Stainless steel blowout-proof stem.
    • Low emission stem seal.
    • Live-loaded two-piece flanged gland.
    • Fully-guided stem reduces side thrust effect - no wobbling.
    • Heavy stainless handle for manual operation. Up to 2" (50 mm) for regular port.
    • Oval handles and extension handles available.
    • Tightness rates: Allowable leakage rate at full AP: ASME/FCI 70-2 Class V. Tighter shutoff available upon request
