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

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.
