Velan, Inc. Cast Split-body Flanged Ball Valves

Severe service metal-seated ball valves for high temperature, abrasive and corrosive applications. Features and benefits • Off-center split-body design allows the use of advanced spiral-wound gaskets. • Maximum temperature for CF8M 1,000°F (538°C), for WCB 800°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 NPS 2 - 12 (DN 50-300) 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 NPS 2 - 4 (DN 50 - 100) FP and NPS 3 - 6 (DN 80 - 150) RP. 6 NPS (DN 150) FP, NPS 8 (DN 200) RP and larger require gear or actuator. Gear or pneumatic actuator available. • Tightness rates: Allowable leakage rate at full δP: 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; and less motion loss and wear in automatic on-off applications.
