Profile of KITZ Cast Steel ValvesKITZ’s wide product range helps customers save onprocurement costs by reducing the number ofsuppliers. It has recently been expanded with theintroduction of low emission service valves thatexceed the US federal environment protectionrequirement of a 500 ppm limit on external leakageof toxic gases and chemicals from valves and otherplant equipment. Every customer is trying hard toimprove their plant life cycle by targeting valvemaintenance problems as an essential managementprogram. KITZ’s low emission service valves offeredin hydrocarbon and chemical industries a realisticand timely solution.To compliment its state-of-the-art production systemand facilities, KITZ has committed itself to qualityassurance management to an extent unparalleled inthe valve industry. Its aggressive employment ofquality management was confirmed by the BureauVeritas Quality International of London when theychose KITZ for their premiere presentation of the ISO9001 certification in 1989, the earliest in the valveindustry.Field applications 1Valve machiningField applications 201

KITZ Low Emission Service ValvesIn the United States, the Federal Clean Air Act was dramatically amended in 1990, to realize the new environmentalprotection policy of a 95% reduction in fugitive emission or leak levels of toxic gases and chemicals from plantequipment. Promulgated in April, 1994, the new law requires all plants handling the toxic gas specified by theEnvironmental Protection Agency, to periodically monitor their plant equipment for detection of leaks exceeding500 ppm, and repair or replace all defective parts immediately. California has exceeded the Federal law with a stateregulation requiring 100 ppm maximum leak level for an astonishing 99% reduction of such an environmentalpollution for the Northern California Region after 1997.Our low emission valves, the proud fruits of several years of trial and error at our laboratory, are designed,engineered, manufactured and tested to now meet the 100 ppm maximum emission level. This is the standardspecification in North America for KITZ flanged and butt-welding end carbon or low alloy steel valves rated Class150, 300 and 600. In other markets, all these low emission valves are optionally available. Major designconsiderations for having upgraded our standard valves to the low emission performers are introduced below.Gland packingKITZ’s original ‘‘SEALEVER ® ’’ flexible graphite packingset, consisting of 4 dieformed flexible graphite rings*and 2 braided flexible graphite rings, combined with aspacer bush for Class 300 and 600 rated valves.*US Patent No. 5522603 & 5573253.

Straightness and roundnessare precision controlled according to KITZ design andmanufacturing standards.YRT Emission Test ResultsIn addition to our in-house lab tests and certifications by Lloyd’s Register of Shipping, a third-party perfomance test was carriedout on a KITZ nominal size 6 Class 300 gate valve at Yarmouth Research and Technology, Maine, USA, according to one user’stesting specifications. The test conditions included an unprecedented 3500 cycle operation of a 99% methane pressurized valvethrough thermal cycles at 350F (177), with the valve stem positioned horizontally to the ground, and the leak level wasmonitored at every 100 cycles, from an aluminum foil housing sealed the valve gland area. In spite of these severe testconditions, the results were in close agreement with findings from the tests made at our laboratory over the last several years.09

Design Features of KITZ Gate Valve Wedges (Discs)Among the four different shapes of wedge gates recognizedby API 600 Paragraph 5.6.1.1 and 5.6.1.2, KITZ hasadopted solid wedges for smaller valves such as nominalsize 2 to 4 of Class 900/1500/2500 gate valves, and flexiblewedges for all other sizes of all pressure classes.H-shaped flexible wedges are featured with mechanicalflexibility to adjust its own shape following the shape ofthe body seats for tightly secured mutual contact. This ispaticularly important when larger gate valves serviceextremely high pressure and temperature, wheretemporary deformation of the valve body always occurs.Operational torque is smaller, seat wear is less and valveclosure is tighter when H-shaped flexible wedges areprovided.Side ViewSolid wedgeFlexible wedgeFront ViewHeavily designed KITZ wedge gates are forged or castsolid, single piece of steel without any welding work.Specially heat-treated wedges are firmly coupled withintegral T-head of the valve stems, which are alsoruggedly designed and specially heat-treated for thehighest possible durability of stem to wedge connection.API 600 Paragraph 5.8.7 particularly emphasizes theimportance of the mechanical strength of thisconnection.As another unique feature, KITZ wedge gates aredesigned for always accurately maintained concentricityand carefully lapped for leakfree contact.Stem-to-Wedge Connection10

Care for Handling Valves1. Before mounting valves:Before mounting valves, be sure that adequate valveshave been prepared to exactly meet the serviceconditions including the maximum design pressuresand temperatures. Foreign objects such as sand orscale may be left in the pipes, and care should betaken to remove all of them by filters or strainers toprotect valve seat surfaces during subsequent valvecommissioning.2. Mounting valves:On mounting valves, clean the inside of pipes again sothat no welding spatter, chips, scale or sand are left.For installation of flanged end valves, flange boltsshould be tightened alternately in a star pattern.Where extraordinary external forces such as pipingstress may be applied to the flanges of valves beingmounted, provide valve supports or any otheradequate protective measures.Check body/bonnet bolting during installation, stressrelaxation of fasteners can occur during transit andstorage.Lubricate stem and yoke sleeve prior to valve operation.KITZ valves are shipped from the factory withonly a light lubricant which facilitates assembly.3. Retightening valves glands:When leakage is detected from the gland area whilethe valve is being in service, the gland nuts should beimmediately retightened. Tighten the gland slowlyand gradually until the leakage stops, while rotatingthe valve handwheel. In case the valve operatingtorque has been found considerably increased afterthese procedures, it is recommended to replace allpacking rings at the time of valve maintenance.4. Replacing packing rings:It is recommended to replace packing rings duringvalve maintenance operation, but never while thevalve is being pressurized in service, except when theline pressure is reduced to the atmospheric level. KITZcast carbon and low alloy steel valves are providedwith the backseats on the bonnet bushing. If leakagefrom the gland area cannot be stopped byretightening the gland nuts, operate the valve to itsfull open position and add a few packing rings orreplace packing rings utilizing sealing function ofthese backseats.Sealing function of backseats is sometimes disturbeddue to rust or other foreign objects trapped inside. Itshould be carefully checked before adding orreplacing packing rings that backseats functionproperly. When the valve is highly pressurized, itsometimes causes danger to replace all of packingrings. In this case, adding a few new rings or replacinga few rings on top of the packing chamber isrecommended as a first aid solution.For replacement of packing rings, first remove thegland nuts and then packing rings. Clean the packingchamber and the valve stem. After checking that allsliding parts are in good condition, securely installnew packing rings. Press new packing rings lightly afew times with the gland and then evenly tighten thegland nuts.30
