JFLOW Ball Valve Manual.pdf

J Flow LD7300 series ball valve installation and maintenance manual provides instructions for proper installation, maintenance, and troubleshooting of the valve. The valve is designed for long-lasting, worry-free service when installed according to the manual's specifications. Key points include:

Storage and handling: Valves should be stored in a fully open or fully closed position, with protective covers in place, and in a clean and dry environment.
Safety precautions: Read the safety section before installation or operation, depressurize the line before disassembly, and wear protective equipment.
Installation: The valve can be installed in either direction, with the pipe flushed of any media that could damage the ball or seats.
Operation: The valve provides tight shut-off when used under normal conditions, and should not be left in a partially open position.
Maintenance: The valve is designed for easy disassembly and reassembly, and internal maintenance may require replacing packing, seats, seals, ball, or stem.
Troubleshooting: Common issues include stem leakage, body joint leakage, and in-line leakage, with procedures outlined for each.
* Disassembly and reassembly: The valve must be in the open position, with no flow through the valve, and removed from the pipeline before disassembly.
