7. – CARE AND MAINTENANCE
Theoperatormustdenemaintenanceandmaintenance-intervalstomeetrequirements.
- Check for body and seat tightness and valve smooth operation without additional tools.
- Check the valve surface inside and outside. Keep valve surface is in good condition and retouch coating protection if
any when needed. If advanced corrosion or erosion is observed, double check service and valve features and replace
the valve properly.
7.1 Parts disasseembly and assembly
- Packing, seats, ball and stem can be easily dismounted by using common tools.
VALVE DISASSEMBLY
-Placethevalveinverticalpositionsothebodyange(part1)leadsontheworkingtable.
- Release any pressure that may be retained in the body cavity by using the drain valve (part 4) or by opening or closing
the main valve. Leave the valve in the closed position to continue the disassembly.
- Remove body bolting (parts 2 & 3) that retains the body halves (parts 1, 7) and remove the seats and ball carefully in
order not to damage the seals sittings.
-Toremovethestemfromtheinteriorofthebody(part.14),rstremovethecapscrew,gasket,O-ring(19,20,21).Once
done there is free access to rest of parts..
- All the parts to be used in the assembly must be cleaned and stored in a dry and secure place. All the sealing surfaces
on the ball, seats, packing and metal faces must be carefully checked for corrosion and or erosion. Seats should have
no metal particles. All damaged parts must be replaced.
VALVE ASSEMBLY
- Before assembly all the sealing surfaces on the ball, seats, seals and metal faces must be carefully checked for dirt,
corrosion or erosion.
-Followtheabovestepsinthereverseordertoreassemblethevalve.Seatsshouldperfectlyt;ifnecessaryslightly
strike with a soft hammer. Once mounted, slowly operate the valve till a complete manoeuvre is covered, to allow perfect
adjustment between ball and seats.
- Seats, stem seals and ball must be lubricated with suitable lubricant. Please contact lubricant supplier for advice. This
will improve overall performance and torque due to less friction.
- After assembly check for leaks and the correct opening and closing of the valve.
After any maintenance work please refer to chapters 5 and 6 for installation / commissioning.
Recommended Spare parts:
Use only original spare parts.
It is advisable to keep packing rings (9), body seats (7), gasket (8) and body union gasket (5) as spare parts. Type and
number of each spare part to be stored according to many factors: service level, valves quantity, etc. In many cases a
good choice is to keep complete valves as spare part.
8. – TROUBLESHOOTING
