How Should We Maintain Globe Valves?
You should also consider some below points:
Regular maintenance of the valve should be needed. You should pay attention to check there is no valve leaking.
If the valve is not working regularly, then cycle the valve. It will prevent the disc from bedding itself in the seat.
You can use a grease gun to grease the crossbar on the nipple. If needed, you should lubricate the spindle.
If packing needs adjustment, you should need to tighten the gland bolts slightly. The gland will be damaged if you over-tighten it. You need to replace the packing if leaking through the gland appears.
