Bronze Globe Valve
Installation, Operation and Maintenance Instructions
Installation
1) Before valve installation thoroughly clean and prepare piping system, be sure mating pipe
threads are free from excessive grit, dirt or burrs.
2) Inspect the valve ports and seating surfaces for cleanliness just prior to installation. Take
care to assure that pipe sealant is not excessively applied to the pipe threads, as to foul the
valve seat.
3) Use pipe sealant on threaded valves, which is recommended for valve, end use.
4) Use solder on solder joint valves, which is recommended for valve, end use.
5) Support the valve to prevent unnecessary stresses induced by the connecting pipe.
6) Operate the valve from the full open to closed position.
7) Verify the tightness of the packing nut after installation.
Operation
1) Globe valves are operated manually. To open, turn the handle in a counterclockwise
2) If the handwheel is difficult to turn, loosen packing nut ¼ to ½ turn. Retighten packing
direction. To close, turn the handle in a clockwise direction.
nut after open-close operation is completed.
Inspection and Maintenance
1) Periodic inspection of the valve is recommended.
2) If a valve develops a stem packing leak, adjust the packing nut to increase the pressure on
the stem packing. The packing nut should be turned in a clockwise direction
approximately ¼ to ½ turn.
3) If tightening the packing nut does not stop the leak, the backseat on rising stem valves
can be used to limit the leakage until circumstances permit a system shutdown and
packing replacement.
4) Stem packing replacement with the valve under pressure and backseated represents a
hazard and should not be undertaken. The hazard is magnified as fluid pressure or
temperature increases or when the fluid is toxic.
