SB-150/300/600 cast metal-seated ball valves

Overview

Category: Quarter-turn valves
Product line: Securaseal® metal-seated ball valves

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.
Valve/packing meets ISO and API Fugitive Emissions Standards, and corrosion test requirements.
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.
