Factory-assembled actuated valves are all adequately adjusted for satisfactory
function and performance. Do not disassemble them for any reason, unless
approved in advance by KITZ Corporation, as it may cause valve malfunction,
valve seat leakage and other technical problems.
Maintenance works for dismantled valves must be carried out in dust-free, clean
places to prevent intrusion of foreign objects into the interiors of valves and
actuators.
During maintenance works and dismantling from or reinstallation on piping, take
care not to damage sliding parts of actuated valves such as shafts and stems,
and prevent foreign objects from sticking to internal and external surfaces.

To remove the valve from a piping, check that no fluid remains within the piping

valve as shown in Fig. 20.
