FLOATING BALL VALVES
TSC Valve manufactures some of the most dependable cast steel Ball Valves in the industry. Our products are manufactured and tested in accordance with respective API, ASME, and ANSI standards. The TSC design offers many features and options beneficial for Oil, Gas, and liquid applications making it one of the most preferred floating ball valves on the market.,
DESIGN DESCRIPTION
-
Split body design with flanged ends for fast installation, in-line maintenance and rebuilding
-
Solid ball construction provides structural integrity and minimizes flow turbulence
-
Mounting pad complies with ISO 5211 for ease and interchangeability of actuation
-
Bottom-loaded blow-out proof stem
-
Investment cast body & end cap on sizes 1/2” to 4”. Sand cast body & end cap on sizes 5”
to 10”
-
Body joint is designed to prevent excessive compression of valve internals, resulting in a consistent and low operating torque
Floating Ball Valve Function
Zero leakage packing chamber design
-
ASME CLASSES : 150-600
THE E-20 PACKING CHAMBER OUTPERFORMS COMPETITIVE DESIGNS
-
Packing chamber design maintains low emissions control for long lasting high cycle life.
-
Self-aligning packing flange is independent of gland for equal compression of packing rings.
-
Upper and lower stem bushing prevent side load on packing rings. Eliminates premature wear, therefore enhancing packing life.
-
Floating stem eliminates thrust washer wear.
-
Stem shoulder assures blowout-proof safety.
-
Cup and cone packing rings for directional compression for a tighter seal and longer life.
-
Anti-static design
Ball-spring device eliminates static electrical
buildup between stem, ball, and body
NPS 1/2–12". A separate external coil spring
device that grounds stem to body is included
in the full size range.

-
Face-to-face dimensions meet ASME B16.10 long pattern or short pattern. Refer to page 15 for actual dimensions.
-
Locking devices standard on lever operated valves.
-
Trunnion-mounted ball on larger valves allows the ball to float in case of fire and shut off on the secondary metal seat.
-
Cavity fillers available for NPS ½"–12".
-
Gear actuators standard(6): 150/300Lb
Full port: NPS 8"–24" (DN 200–600)
Regular port: NPS 10"–24" (DN 250–600)
600Lb: Full port: NPS 6"–12" (DN 150–300)
Regular port: NPS 8"–12" (DN 200–300)
APPLICATIONS
The valves can handle a vast variety of fluids, slurries
semisolids and almost any corrosive service in chemical, oil, petrochemical, gas, pulp, paper processing and other industries. Standard valves with RPTFE seats can handle steam service to 150 psig. Valves with carbon graphite filled PTFE seats are suitable for steam up to 250 psig (17.2 bar).
-
These rugged, versatile, high-performance ball valves can meet NACE specifications(7).
-
Fire tested in accordance with API 607(5). Rev. 5/ISO 10497. (See page 11 for details.)
(1)Floating ball valve optional for NPS 8 (DN 200).
(2)Trunnion optional on NPS 2–3 (DN 50–80) full port valve.
(3)Trunnion optional on NPS 3–4 (DN 80–100) regular port valve.
(4)For latest revision compliance contact your local TSC office.
(5)API 607 Rev. 5 is optional, requires graphite packing.
(6)May be recommended on NPS 6 (DN 150) SB-150/300 full port or NPS 8 (DN 200) 150/300 regular port depending on service conditions.
(7)To ensure these valves meet NACE specifications, this requirement must be confirmed prior to placing the purchase order.
