3 & Valves KITZ K-Metal : Unique Dezincification Resistant (UNS No.C353) Water pollution and employment of new piping material have amplified valve dezincification problems. What is dezincification? The copper alloy used in bronze valves contains zinc, tin, and lead with copper as a base. When bronze valves are subjected to unfavorable service conditions, the zinc component contained in the copper alloy separates from the copper base, and the metal corrodes. This is called dezincification. In case of bronze valve, the body, bonnet, and other cast bronze parts hardly corrode due to the small percent of zinc contained in the alloy. But brass valve parts such as stems, which contain % zinc, often corrodes due to extreme dezincification. What causes dezincification? The following factors cause dezincification. These factors are generally believed to occur together, rather than independently. Excessive aqueous solution in acidity. Warm water containing excessive free carbonic acid with high electric conductivity. 3 High electric conductivity with excessive presence of chlorides and sulfides. 4 Copper or vinyl chloride pipes. 5 Excessive dissolved oxygen. What is K-Metal? To prevent dezincification, KITZ Corporation developed K-Metal as the stem material of bronze/brass valves. The test data given below compare the properties of K-Metal with ASTM B4, B6 and B6, and also with another dezincification resistant material introduced by one of our competitors in Japan. The comparisons prove K-Metal's overall high performance and explain why KITZ bronze/brass valves offer longer service life. The extent of the corrosion and dezincification compared here are the values recorded after two weeks of laboratory experiments. Australian Standard C36 was applied to the measurement of dezincification depth.

18 Butterfly Valves Precautions for Trouble-free Operation of KITZ Butterfly Valves Valve Selection. Ensure to select a valve with design specifications which meet the fluid type and the pressure and temperature conditions required.. Lubricants are applied to discs, rubber seats and PTFE seats as standard to protect their surfaces. Oil-free treated types are available as option. Contact KITZ Corporation or its local distributors for the details. 3. Contact KITZ Corporation or its local distributors for service with pulverulent bodies. Storage and Handling Valves must be stored in dry, clean and corrosion-free environment with no direct exposure to the sun, leaving valves open by 0 for prevention of permanent distortion of resilient seats. Refrain from overloading valves and their actuators, such as storing them in piles or placing other objects on them. Mounting on Pipelines. Valves must be mounted on flanges only after flanges have been welded to pipes and cooled down to the atmospherical temperature. Otherwise, welding heat may affect the quality of resilient seats.. Edges of welded flanges must be machined for smooth surface finish so that they may not damage resilient seats during valve mounting. Flange faces must be free from damage or deformation, and be cleaned to remove rust or any other foreign objects so that there will be no concern of external leakage through valve and flange connections. Gaskets are not required for mounting KITZ DJ series butterfly valves. 3. Clean flanges and pipe bores to thoroughly remove welding spatters, scales and other foreign objects which may have been left inside. 4. Accurate centering of each couple of upstream and downstream pipes is essential for trouble-free operation of valves mounted between them. Incorrect centering shown in Fig. must be by all means avoided. 5. For valve mounting, set jack bolts under the pipes for flat support at the same height, and adjust the flange-to-flange distance so that some 6 to 0 room may be allowed beside the both sides of the valve body. Remember that valves here must be left open only by 0 from the fully closed position. 6. Set two bolts into the lower mounting guides of a valve and mount it carefully so that flange faces may not damage resilient seats. (Fig. ) 7. Then set another two bolts into the upper mounting guides of a valve, ensuring the correct centering between pipes and the valve. 8. Trially open the valve to check to see if there is no disturbing contact between the valve disc and the flanges. 9. Remove the jack bolts, set all bolts around the valve body and tighten them alternately and diagonally till the flanges contact the valve body (Fig. 3 and 4). Fig. Fig. (a) (b) Fig.3 Fig.4 7

19 Butterfly Valves 0. For mounting actuated valves, provide valve supports to prevent bending of valve necks and reduce valve and pipe vibration.. Don t step on valve necks or valve handwheels.. Don t mount valves of 3 and larger with their operations upside down. 3. Don t mount butterfly valves directly to check valves or pumps, which may cause damage to them by the disc contacts. 4. Don t mount valves to downstream sides of elbows, reducers or regulating valves where fluid velocity changes. It is recoended to install valves approx-imately 0 times of the valve nominal sizes away from them for such cases.. Mount valves taking consideration of the effects which discs are given by fluid velocity or pressure chages in the pipings. Refer to the illustrations. (Fig.5) Contact KITZ Corporation or its local distributors for the details. Valve Operation. Valves equipped with manual operators such as levers, and handles of gears must be ONLY MANUALLY operated. Application of an excessive external force to operate valves may result in malfunction of valves and their operators.. Ensure to fully open valves before a loop test of the piping system is carried out with line pressure higher than the nominal pressure of tested valves. Never use closed valves in place of blind flanges. 3. When valves need to be dismantled from pipes for maintenance or any other cause, ensure to thoroughly releave the line pressure beforehand. Loosening piping bolts under line pressure causes a danger. Any residual fluid left inside the pipeline must be completely drained. 4. Users should contact KITZ Corporation or its local distributors for technical advice, when valves should be continuously pressurized while left open by 30ϒ or less. 5. Don't use position indicators to operate valves, or overload position indicators. This may cause damage to indicators. 6. Ensure to use blind flanges when butterfly valves are mounted at the end of pipelines. 7. Standard actuators are referenced in this catalog for actuated valve operation. Contact KITZ Corporation or its local distributors for mounting optional actuators. 8. Contact KITZ Corporation for service at hopper or pump outlets. 9. Avoid touching gear operators and actuator stopper bolts accidentally. 0. It is recoended to perform periodical inspection for Making sure of valve opening degree Checking loosened bolts and leakage at each connection Checking vibration and noise. Refer to instruction manual for other precautions. Also refer to actuator catalogs and instruction manuals for actuated valves.
