• TypeT1

    DESIGN FEATURES:

    • 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

  • SB150

    DESIGN FEATURES

    • 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.
