Product operation instruction


1. Pipe flange standards should conform to butterfly valve standards; suggest using welding neck flange, specialized flange for butterfly valves or integral pipe flange; do not use slip-on welding flange, supplier must agreed before user can uses slip-on welding flange.
2. The use of pre-installation conditions should be checked whether the use of butterfly valves with the same performance. 
3. Before the installation user should clean the sealing surface of valve cavity, make sure no dirt attached; simultaneously clean the pipe for welding slag and other debris.
4.When installing, the disc must be in closed position to ensure that the disc do not collide with the pipe flange.
5. Both valve seat ends act as flange seal, extra seal is not needed when installing the butterfly valve.
6. The butterfly valve can be installed at any position (vertical, horizontal or tilt). Butterfly valve with big size operator may need bracket.
7. Collide when transporting or storing the butterfly valve may cause butterfly valve reduce its sealing ability. Avoid butterfly valve disc from bumping to hard objects and it should be open at 4 ° to 5 ° angle position in order to maintain sealing surface from damaging during this period.
8. Confirm correctness of flange welding before installation, welding after installation of the butterfly valve may cause damage to the rubber and preservation coating.
9. When using butterfly valve operated by pneumatic, the air source should maintain dry and clean to avoid foreign bodies from entering pneumatic operator and affect working performance.
10. Without special requirements noted in purchasing order of the butterfly valve can only be mounted vertically and for interior use only.
11. Case of disorder, reasons should be identified, troubleshooted, should not knock, hit, prize or lengthen the lever operator by arm of force to forcibly open or close the butterfly valve.
12. During the storage and unused period, the butterfly valves should kept dry, sheltered in shade and avoid harmful substances surrounding from erosion.
