10. For mounting actuated valves, provide valve supports to prevent bending of valve necks and reduce valve and pipe vibration.

11. Don’t step on valve necks or valve handwheels.12. Don’t mount valves of DN350 and larger with their operations upside

down.13. Don’t mount butterfly valves directly to check valves or pumps,

which may cause damage to them by the disc contacts.14. Don’t mount valves to downstream sides of elbows, reducers or

regulating valves where fluid velocity changes. It is recommended to install valves approx-imately 10 times of the valve nominal sizes away from them for such cases.

15. Mount

16. The protection rating of manual operators is up to IP65, appropriate protection should be taken for outdoor use.

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.

1. 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.

2. 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 30 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.10. It is recommended to perform periodical inspection for

e of valve opening degree

11. Refer to instruction manual for other precautions. Also refer to actuator catalogs and instruction manuals for actuated valves.Fig.5

Note:Centering with "centering sleeves" is required for the valves coupled with them for accurate centering for sizes of 80mm, 125mm and 200mm (XJ series).(Fig.6)

WARNINGDon't disassemble necks while the valve is pressurized to prevent stem blow-out. Also don't dismantle valve operating devices, since it may cause valve discs rotate and result valve malfunction.
