The problem of turning the flywheel in the valve
The problem of turning the handwheel in the valve arises when they are opened less than once a year and are deprived of attention from the service personnel. The reason lies in the scale on the sealing surfaces.
Troubleshooting Tips:
Remove the valve top cover and clean the sealing surfaces of the disc and body.
If necessary, grind the rubbing surfaces.
Attention! Knocking on the stem is strictly prohibited, as the guide nut may be torn off.
