INSPECTION & MAINTENANCE OF VALVES
Nov 21, 2022
1 - Other than cycling of the valve from open to closed position periodically. Inspection and preventative maintenance are not required.
2 – Normal stem packing wear can be compensated for by tightening the packing nut. Tighten the packing nut clockwise in 1/8 turn increments until observed leakage stops.
Over tightening will increase the torque required to operate the valve and result in excessive wear on the packing.
3 - Do not repack valves under pressure. Repair or replacement of two-piece ball valves internal parts is not recommended. Damage can occur to the body and tailpiece during disassembly that would make the valve inoperable.
