Proper safety equipment and apparel should be worn when preparing to service a valve. Observe the
following general warnings:
• A valve is a pressurised mechanism containing energised fluids under pressure and
consequently should be handled with appropriate care.
• Valve surface temperature may be dangerously too hot or too cold for skin
contact.
• Upon disassembly, attention should be paid to the possibility of releasing
dangerous and or ignitable accumulated fluids.
• Ensure adequate ventilation is available for service.
3.1 GLAND PACKING ADJUSTMENT
Tools Required: - aside from standard wrenches (for bonnet cap screws and packing gland nuts) the only
tool needed for minor Australian Pipeline Valve valve maintenance is a packing hook.
Special care is to be placed in the tightening of the gland nuts during installation, in order to get the
proper packing adjustment and functionality.
The packing gland should be checked periodically in service and tightened as necessary to stop leakage
around the stem. Tighten in a manner to develop uniform loading on the gland. Tighten only enough to
stop the leak.
