Precautions for Troublefree Operation of KITZ Butterfly Valves Valve Selection 1. Ensure to select a valve with design specifications which meet the fluid type and the pressure and temperature conditions required.. ubricants are applied to discs, rubber seats and PTFE seats as standard to protect their surfaces. Oilfree treated types are available as option. Contact KITZ Corporation or its local distributors for the details.. Contact KITZ Corporation or its local distributors for service with pulverulent bodies. Fig 1 Storage and andling Valves must be stored in dry, clean and corrosionfree environment with no direct exposure to the sun, leaving valves open by 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 1. Please reference product drawing to quote the flange of pipeline.. Valves must be mounted on flanges only after flanges have been welded to Fig 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 WJA series butterfly valves.. Clean flanges and pipe bores to thoroughly remove welding spatters, scales and other foreign objects which may have been left inside.. Accurate centering of each couple of upstream and downstream pipes is Essential for troublefree operation of valves mounted between them. Incorrect centering shown in Fig. 1 must be by all means avoided. Fig. For valve mounting, set jack bolts under the pipes for flat support at the same height, and adjust the flangetoflange distance so that some to room may be allowed beside the both sides of the valve body. Remember that valves here must be left open only by from the fully closed position. (Fig. & ) 7. Set two bolts into the lower mounting guides of a valve and mount it carefully so that flange faces may not damage resilient seats.. Then set another two bolts into the upper mounting guides of a valve,ensur ing the correct centering between pipes and the valve. 9. Trially open the valve to check to see if there is no disturbing contact between the valve disc and the flanges.. 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. & ). 11. For mounting actuated valves, provide valve supports to prevent bending of valve necks and reduce valve and pipe vibration. 1. o not step on valve necks or valve hand wheels. 1. o not mount valves of N and larger with their operations upside down. 1. o not mount butterfly valves directly to check valves or pumps, which may cause damage to them by the disc contacts. 1. on t mount valves to downstream sides of elbows, reducers or regulating valves where fluid velocity changes. It is recoended to install valves approximately times of the valve nominal sizes away from them for such cases. 1. Mount valves taking consideration of the effects which discs are given by fluid velocity or pressure changes in the pipings. Refer to the illustrations.(fig.) Valve Operation 1. Valves equipped with manual operators such as levers, and handles of gears must be ONY MANUAY 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.. When valves need to be dismantled from pipes for maintenance or any other cause, ensure to thoroughly relieve the pipeline pressure beforehand. oosening piping bolts under line pressure causes a danger. Any residual fluid left inside the pipeline must be completely drained.. Users should contact KITZ Corporation or its local distributors for technical advice, when valves should be continuously pressurized while left open by 0 or less.. o not use position indicators to operate valves, or overload position indicators. This may cause damage to indicators.. 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.. Contact KITZ Corporation for service at hopper or pump outlets. 9. Avoid touching gear operators and actuator stopper bolts accidentally.. 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 11. Refer to instruction manual for other precautions. Also refer to the actuator catalogs and instruction manuals for actuated valves. WARNING o not disassemble necks while the valve is pressurized to prevent stem blowout. Also do not dismantle valve operating devices, since it may cause valve discs rotate and result valve malfunction. Fig Fig Fig Note: Centering with centering sleeves is required for the valves coupled with them for accurate centering(fig. 7). Fig 7 09
