SoCalGas to Install New Valves to Enhance Pipeline Safety

Southern California Gas Company will upgrade or replace 50 to 60 pipeline valves in 2017 to further enhance the safety of its system. The upgraded valves will feature the latest technology that allow operators to control the valves from a remote location, or that automatically shut off the valve if a drop in pressure is detected. The effort is part of SoCalGas’ Pipeline Safety Enhancement Plan, a multi-billion-dollar program that tests and updates the natural gas pipeline infrastructure in Southern California.

As part of the project, the company will upgrade or replace existing valves with Remote Control Valves, which can be opened or closed remotely by system operators from a central control location, or Automatic Shut-off Valves, which are equipped with a control device that automatically triggers a mechanism that shuts off gas flow in the event of a large pressure drop.

Since SoCalGas began using this new valve technology five years ago, the PSEP program has replaced or retrofitted more than 100 valve locations. PSEP has five separate project teams dedicated to valve upgrades and retrofits, and will continue to replace and retrofit valves through 2022. The company completed 56 valve upgrade projects in 2016.
