Gas Shutoff Valve Certification Program

There are three types of gas shutoff devices. These are manual shutoff valves, earthquake sensitive automatic shutoff valves, and excess flow automatic gas shutoff valves. The DSA certification program deals with the latter two types of devices:

  1. Earthquake sensitive gas shutoff valves (ESV) and
  2. Excess flow automatic gas shutoff valves (EFV).

DSA derives its authority to certify these valves from the Health and Safety Code.

For questions regarding the state certification program for gas shutoff valves, contact Raghubir Gupta at Raghubir.Gupta@dgs.ca.gov or 916.322.0719.
