Natural Gas
6480 By-Pass Procedure
5/21
3210-538
Valve Rating 25 PSIG
NOTE: These valves are designed for use with natural, manufactured or LP gas only.
1. Read instructions and reference pressure rating on integral valves before installation or maintenance of meter bar.
2. Inspect valves for foreign material. Remove any foreign material.
3. Always apply a quality grade pipe thread sealant to the pipe before installation - do not use teflon tape. Excess pipe
sealant contacting the ball surface may cause the valve to leak.
4. Always wrench nearest to connection point. Never insert a tool into the port area of the valves to thread bar onto
the pipe. A backup wrench should be used on the end pieces when installing swivels. Incorrect tightening or
overtightening of the bar on installation can cause bar failure.
5. Installation torques should be reduced when using pipe heavier than schedule 40.
6. Reference the bypass procedure shown below and on reverse side.
7. Lock the valves to prevent unwanted operation or access. Valves can be locked in "NORMAL FLOW" (through the
meter) or in "BYPASS MODE".
8. The bypass meter bars are designed to provide uninterrupted gas service to a service during gas meter maintenance. The
ability to maintain gas flow to the service comes from the valves' oversized ports, which allow for a minimum-flow condition
during valve operation.
