KITZ Steel Ball Valves, Floating Ball Design Pressure-Temperature RatingsThe pressure-temperature ratings of ball valves are determined,not only by valve shell materials, but more essentially by sealingmaterials, used for ball seats, gland packing and gaskets.Sealing materials may be high molecule, or rubber, but thechoice is limited by the characteristics of the service fluid,working temperatures, working pressures, velocity of fluid, andoperational frequency of valves.As it is very difficult to predetermine the exact pressuretemperature rating for all kinds of fluid under all imaginableconditions, we have prepared general rating charts for non-shock fluid service here, based on our past experiences both inthe field and in our laboratory.In case of extraordinary service conditions as mentioned below,contact KITZ Corporation or its distributors for technical advice:1. Valves shall be left fully closed for a long period of time underhigh temperature or high differential pressure.2. Valves shall be frequently operated under high temperatureor high differential pressure.3. Frequent change of line pressure or temperature.HYPATITE PTFE is the standard seat material for KITZ ball valves. Specify virgin PTFE or carbon-filled PTFE when required. The body ratings shownhere are for ASTM A216 Gr. WCB and A351 Gr. CF8M. For the pressure ratings of other valve shell materials, refer to the latest edition of ASME B16.34.FILLTITE is a specially reinforced ball seat, made by using carbon based fillers into PTFE at higher rate than conventional carbon filled PTFE, whichgreatly improves heat and abrasion resistance. The material shows excellent operability, durability, chemical resistance and sealing performance at a hightemperature of 300 . In addition, the ball seat is replaceable with the most of our conventional ball seats, so it also has the cost advantage.6

Its resistance to high or low temperature, creep orcompression, abrasion and corrosion is all outstanding. As anoption, KITZ SWELLESS ball seats principally made of PFAare recommended specifically for monomer service. Thisepoch-making new seat maximizes resistance to thepermeation of monomer into its molecular structure (generallyknown as a “swelling” problem) which causes seat deformationand seriously affects shut-off function of valves in styrene andbutadiene monomer service.12Simplified actuator mountingFor 150/300 SCTDZ/UTDZM and SCTA/UTAM Series ballvalves, ISO 5211 actuator mounting pad is integrally providedfor uniformly simplified mounting of any actuators provided withvalve mounting flanges designed to ISO 5211 dimensionalrequirement. 150UTBM Series ball valves are provided withKITZ standard integral actuator mounting pad.Easy maintenanceSplit body design for KITZ SCTDZ/UTDZM Series provides theconvenience of very easy maintenance critically required forprocess plants.

KITZ Steel Ball Valves, Floating Ball DesignSeven Safety Considerationsfor KITZ 150/300 SCTDZ/UTDZM 150UTBM and 150/300 SCTA/UTAM Series Ball Valves1. Double “D” stem head design provides mountingof the lever handle always in parallel to the flowpassage. Misaligment of the handle is thusprevented. (Fig. 1)StemStem CollarBodyAntistaticdevicesFlow direction2. The lower end of the stem is designed with anintegral collar to be blowout-proof. It also functions as the backseat for assured stem sealing.(Fig. 2)Top of stem3. An antistatic feature is provided to ensureelectrical continuity between ball, stem, and body.(Fig. 2)BallHandleFig. 14. Facility for mounting a locking device for prevention of accidental valve operation is provided.Fig. 2BodyBodySeatMetal-to-metalcontact5. Plant fires are a serious concern for soft-seatedball valves because of possible fluid leakage andconsequent increase of the fire magnitude causedby deterioration of resilient sealing materials.KITZ ball valves are engineered for firesafety andsuccessfully fire tested to minimize both externaland internal fluid leakage after plant fires. Theyhave post-fire metal-to-metal contact of all sealingareas such as:Fig. 3 (Before fire)PackingMetal-to-metalcontactBearing Contact between ball and valve shell(Fig. 3 & 4)Fig. 4 (After fire)WasherStemGasket Contact between stem and valve shell(Fig. 5 & 6) Valve shell coupling flanges of split body design(Fig. 7 & 8) Contact between valve body and insert of uni-body design (Fig. 9)The problem of external fluid leakage is moreserious than internal leakage through the valvebore because of the fear of fueling the fire. Toprevent this, KITZ ball valves may be ordered withflexible graphite packing and gaskets, whichare extremely heat resistant, and not affected bythe fire.6. The surface of stem and stuffing box, and interfaceclearance of stem-to-gland, stem-to-body andgland-to-stuffing box are precision controlled onmachining and assembly for low emission service.A Belleville spring washer is employed for liveloading on gland packing rings, to minimize needof gland retightening for low emission service.7. A provision of cavity pressure relief is incorporated into precision engineered KITZ HYPATITE PTFE ball seats for the ultimate safety.
