2 ultimate performance and efficiency. Its ma feature is a sgle undisturbed flow of processes from foundry operation to mache shops, assembly shops, tests, spections and the fal valve makeup works. uman engeered layouts of all manufacturg processes are equipped with stateof-the-art machery and apparatuses, makg KITZ production efficiency unrivaled anywhere Japan. KITZ s wide product range helps customers save on procurement costs by reducg the number of suppliers. It has recently been expanded with the troduction of low emission service valves that exceed US federal environment protection requirement of 500 ppm limit on external leakage of toxic gas from valves and other plant equipment. Every customer is tryg hard to improve his plant life cycle by targetg valve matenance problems as his essential management program. KITZ s low emission service valves offer hydrocarbon and chemical dustries a realistic and timely solution. To compliment its state-of-the-art production system and facilities, KITZ has committed itself to quality assurance management to an extent unparalleled the valve dustry. Its aggressive employment of quality management was confirmed by the Bureau Veritas Quality International of London when they chose KITZ for their premiere presentation of the ISO 9001 certification 1989, the earliest the valve dustry.

10 esign Features of KITZ Gate Valve Wedges (iscs) Among the four different shapes of wedge gates recognized by API 600 Paragraph 2.3.1, KITZ has adopted solid wedges for smaller valves such as 1 1 /2 to 4 of Class 150 / 300 / 900 / 1500 / 2500 (excludg class 600) gate valves, and flexible wedges for all other sizes of all pressure classes and 2" & larger of class shaped flexible wedges are featured with mechanical flexibility to adjust its own shape followg the shape of the body seats for tightly secured mutual contact. This is paticularly important when larger gate valves service extremely high pressure and temperature, where temporary deformation of the valve body always occurs. Operational torque is smaller, seat wear is less and valve closure is tighter when -shaped flexible wedges are provided. Side View Solid wedge Flexible wedge eavily designed KITZ wedge gates are forged or cast solid, sgle piece of steel without any weldg work. Specially heattreated wedges are firmly coupled with tegral T-head of the valve stems, which are also ruggedly designed and specially heat-treated for the highest possible durability of stem to wedge connection. API 600 Paragraph particularly emphasizes the importance of the mechanical strength of this connection. Front View As another unique feature, KITZ wedge gates are designed for always accurately mataed concentricity and carefully lapped for leakfree contact. -to-wedge Connection 9

12 KITZ Low Emission Service Valves In the United States, the Federal Clean Air Act was dramatically amended 1990, to realize the new environmental protection policy of a 95% reduction fugitive emission or leak levels of toxic gas from plant equipment. Promulgated April, 1994, the new law requires all plants handlg the toxic gas specified by the Environmental Protection Agency, to periodically monitor their plant equipment for detection of leaks exceedg 500 ppm, and repair or replace all defective parts immediately. California has exceeded the Federal law with a state regulation requirg 100 ppm maximum leak level for an astonishg 99% reduction of such an environmental pollution for the Northern California Region after Our newly developed low emission valves, the proud fruits of several years of trial and error at our laboratory, are designed, engeered, manufactured and tested to now meet the 100 ppm maximum emission level. This is the standard specification North America for KITZ flanged and butt-weldg end carbon or low alloy steel valves rated Class 150, 300 and 600. In other markets, all these low emission valves are optionally available. Major design considerations for havg upgraded our standard valves to the low emission performers are troduced below.

Low emission acceptance test While no official testg standard is available as of March 1, 2000, KITZ Corporation has developed its own test method and evaluation criteria basg on the results of laboratory tests carried out for the last several years. Most significantly, KITZ employs 10 ppm as the acceptance criteria for the random test done prior to shipment to customers, consideration of stress relaxation of packg material durg transportation and storage. iametrical terface clearance 20 to 32 mils (0.5 to 0.8 mm) : to gland 20 to 32 mils (0.5 to 0.8 mm) : to bonnet bushg 4 to 12 mils (0.1 to 0.3 mm) : Gland to stuffg boxs 16 to 32 RMS surface fish.

21 Care for andlg Valves 1. Before mountg valves: Before mountg valves, be sure that adequate valves have been prepared to exactly meet the service conditions cludg the maximum design pressures and temperatures. Foreign objects such as sands or scales may be left the pipes, and care should be taken to remove all of them by filters or straers to protect valve seat surfaces durg subsequent valve commissiong. 2. Mountg valves: On mountg valves, clean the side of pipes aga so that no weldg spatters, chips, scales or sands are left. For stallation of flanged end valves, flange bolts should be tightened alternately and diagonally. Where extraordary external forces such as pipg stress may be applied to the flanges of valves beg mounted, provide valve supports or any other adequate protective measures. For replacement of packg rgs, first remove the gland bolts and then packg rgs. Clean the packg chamber and the valve stem. After checkg that all slidg parts are good condition, securely stall new packg rgs. Press new packg rgs lightly a few times with the gland and then evenly tighten the gland. KITZ Product Warranty All KITZ cast carbon and low alloy steel valves are guaranteed for 12 months after placement service, but not exceedg 18 months after shipment from the factories of KITZ Corporation, provided that the valves are properly handled accordg to the relevant KITZ operation manual. 3. Retighteng valves glands: When leakage is detected from the gland area while the valve is beg service, the gland should be immediately retightened. Tighten the gland slowly and gradually until the leakage stops, while rotatg the valve handwheel. In case the valve operatg torque has been found considerably creased after these procedures, it is recommended to replace all packg rgs at the time of valve matenance. 4. Replacg packg rgs: It is recommended to replace packg rgs durg valve matenance operation, but never while the valve is beg pressurized service, except the le pressure is reduced to the atmospheric level. KITZ cast carbon and low alloy steel valves are provided with the backseats or bonnet bushes. If leakage from the gland area cannot be stopped by retighteng the gland, operate the valve to its full open position and add a few packg rgs or replace packg rgs utilizg sealg function of these backseats. Sealg function of backseats is sometimes disturbed due to rust or other foreign objects trapped side. It should be carefully checked before addg or replacg packg rgs that backseats function properly. When the valve is highly pressurized, it sometimes causes danger to replace all of packg rgs. In this case, addg a few new rgs or replacg a few rgs on top of the packg chamber is recommended as a first aid solution. 20
