earthquake safety valve brands

​Seismic shut-off valves are a simple, but effective way to ensure you never experience a gas fire after an earthquake. They are designed for earthquakes, accidents and any event of impact. We have installed thousands of automatic gas shut off valves to the manufacture’s specification to ensure safe, trouble free use.

The seismic valves work on a simple, consistent and accurate principle. A sensor moves when the valve is subjected to a 5.4 magnitude or larger earthquake, releasing the valve float which blocks the line and prevents gas going in to the building. The valve is then manually reset once a safety inspection has been done and you’re sure there are no leaks in the building.

Each valve is tested and certified before leaving the factory to meet approval from the State Board of Architect and LA Counties stringent requirements. They are tested to ASCE 25-97, State of California 12-23-1 & ANSI Z21.70-1981 Standards for Seismic Gas Valves.

Some cities and counties in California have regulations that require the installation of automatic gas shut-off devices, which may include excess flow gas shut-off valves and/or seismic gas shut-off valves. Regulations vary, but generally apply to new building construction, or significant alterations or additions to existing buildings.

If a customer installs an automatic gas shut-off valve, it should be one that is certified by the State of California and it should be installed by a licensed plumbing contractor in accordance to the manufacturers instructions.PG&Edoes not install or service seismic actuated or excess flow gas shut-off valves, or recommend specific contractors for customer applications.

​Non-emergency shut-offs will occur if the automatic gas shut-off is not installed according to manufacturer’s specifications. For example, the impact of heavy vehicles can trigger a non-emergency shut-off. They operate on movement and shut off the supply of gas to a building, when triggered by a 5.4 magnitude or larger Earthquake.

While it"s possible to manually shut off your natural gas, the following specialized valves are available that can automatically shut off your service in case of an emergency:

Earthquake natural gas shut-off valve (also known as a seismic natural gas shut-off valve) automatically shuts off your natural gas service when an earthquake of a sufficient magnitude occurs at your home.

An excess-flow valve (EFV) automatically closes and restricts the flow of natural gas in the event an underground pipe is damaged or if there is a significant increase in the flow of natural gas to the meter.

If you want to have an earthquake natural gas shut-off installed, or are required to have one by your insurance company or the local Department of Building and Safety, the valve must be installed on your house line.

Under the regulations of the California Public Utilities Commission (CPUC), General Order 112-E, only SoCalGas® or its certified contractors are authorized to operate the natural gas service shut-off valve.

When you hire a qualified professional to install your earthquake valve, you"ll need to make sure that the valve is installed on your house line, not on SoCalGas" facilities. SoCalGas" facilities include all of the pipe fittings installed and maintained by SoCalGas, up to and including the last elbow or tee connecting to your house line. See the diagram below for to see where your house line starts.

All unauthorized valve installations found on SoCalGas" facilities will be removed. In addition, earthquake valves are not permitted in utility curb meter vaults.

If an earthquake or other significant event causes your earthquake shut-off or excess-flow valve to close, you can follow the manufacturer"s instructions for resetting the valve so that natural gas flows again. However, we recommend that you contact a qualified professional or SoCalGas to reset the valve, and to perform a safety check of your natural gas appliances before they are placed back in operation to verify that no natural gas leaks exist, and to re-light your pilot lights.

Remember that following a major emergency it may take many days or even weeks before someone can come to your location. (SoCalGas charges a fee to reset valves and re-light pilot lights when your earthquake shut-off valve has closed due to a non-earthquake occurrence.)

Price: The cost of the valve is going to vary based on the type and size of the valve, as well as the installation requirements and the company installing it.

Choosing a valve: In order to choose the right valve size and manufacturer, contact your local Department of Building and Safety to find out their earthquake valve requirements.

Where to buy a valve: You can purchase an earthquake valve at supply retailers, licensed plumbing contractors, or directly from the valve manufacturer.

Using a contractor: You can hire a qualified professional to install the earthquake or excess-flow valve on your house line. SoCalGas will not install a valve for you.

Effective February 10, 2002, California Public Utility Commission (CPUC) Decision 01-11-068 prohibits installation of an earthquake valve on SoCalGas" facilities. In addition, SoCalGas no longer installs earthquake shut-off valves for its customers, and does not allow any customer owned equipment, including excess-flow valves, be installed on SoCalGas" facilities.

If you have an earthquake valve that was installed by SoCalGas or one of its authorized contractors on or before the February 10, 2002 cutoff date, that is located on SoCalGas" facilities, with proper documentation your installation may be allowed to remain in place. Authorized contractors are those who participated in SoCalGas" earthquake program and were trained by SoCalGas to work on their facilities.

Additional information regarding earthquake valves and natural gas service restoration after a valve activates can be found in Tariff Book, Rule 10, Section G, "Earthquake Valve Service."

An Excess Flow Valve, or EFV, is a safety device installed on natural gas distribution pipelines to automatically close and restrict the flow of natural gas in the event an underground pipe is damaged or if there is a significant increase in the flow of natural gas to the meter. These conditions are typically caused by digging or construction but can also be caused by damage to your natural gas meter by a vehicle impact.

EFV can reduce the risk of explosions, fires, and personal injury because they close or restrict any unplanned or excessive natural gas flow. Installation of an EFV will not protect a customer from household appliance malfunctions, small punctures in underground pipelines, and pipeline damage from earthquakes or flooding. It is

Surface-controlled subsurface safety valves (SCSSVs) are critical components of well completions, preventing uncontrolled flow in the case of catastrophic damage to wellhead equipment. Fail-safe closure must be certain to ensure proper security of the well. However, this is not the only function in which it must be reliable—the valve must remain open to produce the well. Schlumberger surface controlled subsurface safety valves exceed all ISO 10432 and API Spec 14A requirements for pressure integrity, leakage acceptance criteria, and slam closure.

Through decades of innovation and experience, Schlumberger safety valve flapper systems are proven robust and reliable. The multizone dynamic seal technology for hydraulic actuation of subsurface safety valves is a further improvement in reliability performance when compared with traditional seal systems in the industry.

The multizone seal technology is currently available in the GeoGuard high-performance deepwater safety valves, which is validated to API Spec 14A V1 and V1-H.

California is known for its gorgeous beaches, blue skies, warm weather, and unfortunately, its earthquakes. Yes, it is one of the states that’s the most prone to earthquakes in all of the lower 48 states. If you are a California native, then you have become somewhat used to experiencing the occasional tremor. You also know some of the precautionary steps you need to take with your home to make sure it is as safe as possible during an earthquake. That includes installing earthquake gas shut-off valves, something we are well accustomed to doing at Boss Plumbing.

It is a fact that earthquakes will continue to occur. While we cannot control them or predict them, there are preventative measures you can take to help protect your family and personal property. Having a qualified professionally installed earthquake valve on your gas meter is one of the most economical and reliable ways to be sure the gas is safely shut off in a major earthquake. We all remember the significant seismic activity that led to a large seismic event that transpired in the late 1990s. Though we have not experienced one of that magnitude since then, it has generated the necessary awareness for protective services like earthquake valves.

An earthquake gas shut-off valve automatically shuts off the flow of gas supply and gas service to your home when an earthquake of a sufficient magnitude occurs in and around your home. This type of valve must be installed on your house line, never on the public gas line, and must be done by a licensed plumber such as Boss Plumbing.

If a powerful earthquake were to hit California, it could break gas pipes, leading to a hazardous gas leak. This type of leak is hazardous inside a structure. If the gas, which is highly flammable and dangerous, gets trapped and builds up, it can become very explosive. If an earthquake starts a fire and comes in contact with gas inside a structure, that could trigger an explosion.

Earthquake gas shut-off valves are specifically designed to react to major seismic earthquakes that measure 5.4 or higher on the Richter scale. This device helps prevent not only the devastating aftermath of an earthquake itself, but also the broken pipes, leaking gas, and damaged service lines that often occur in the immediate wake of a major seismic event. Utility companies recommend that after the shaking of an earthquake to immediately shut off the gas but some people may not be able to do this if they are at work or simply away from home. A gas shut-off valve takes care of this automatically.

Earthquake gas shut-off valves are installed on the gas meter of a home or business. When it detects the kind of major shaking that accompanies a significant earthquake, it will automatically cut off gas service to the property if an accumulation of gas enters the building or if a pressure surge occurs downstream of the valve. These valves should be installed on every active gas meter and should typically be done by a well-qualified Boss Plumbing contractor who will ensure proper installation and function.

The answer to this question is simple: as soon as possible! Earthquake gas shut-off valves are quick and easy to install. All you have to do is contact a reputable plumber such as Boss Plumbing. We are certified and experienced in installing this type of equipment under the California Utilities Commission. We’ll be able to install your shut-off valve correctly so that it will perform its job.

Our skilled service technicians will decide what earthquake gas shut-off valve is best for you and your property. There are two kinds of earthquake shut-off valves on the market; typically the option will consist of a pressure-sensitive valve that kicks in due to the excessive gas flow or a motion-sensitive valve that employs a motion-sensing ball detecting movement in a pipe, likely to be caused by an earthquake. Both of these valves are effective methods of shutting down natural gas flow in the event of an earthquake.

The motion-sensing valve works by seating a metal ball bearing above the pipe, suspended on a small rubber or metal ring. In the event the pipe is shaken, the ball dislodges itself and falls into the pipe, essentially cutting off gas flow If it happens to block off the gas then you will need to have the pipes inspected by a professional Boss plumbing contractor to ensure there is no breakage prior to having the ball bearing fished out and the gas flow re-initiated.

This excess flow valve sensor is a slightly more sophisticated method that involves a sensor to determine the gas flow of a pipe. These sensors are equipped with data on just how much gas is appropriate for the location they’re serving — from a small home to a large business. If gas begins to flow at an accelerated rate, they assume a break or leak has occurred and gas service is immediately shut off.

These setups do have one flaw, however: they often fail to detect very small leaks, which are equally common after earthquakes, and equally lethal once enough gas has leaked into the structure. The differences between these two types of earthquake shut-off valve installations, and what they mean for your building, are why it’s always important to contact a qualified Boss Plumbing service technician to help you make the decision and perform a sound installation.

Suppose an earthquake or another significant event causes your earthquake shut-off or excess-flow valve to close. In that case, you can follow the valve manufacturer’s instructions regarding resetting the valve for natural gas to flow again. At Boss Plumbing, we recommend that you contact a licensed plumber to ensure that you’re following the necessary steps to reset the valve, not to mention performing a safety check of your natural gas appliances before they’re placed back online. This ensures there are no leaks when you reignite your pilot lights.

Earthquake gas shut-off valves are fairly simple to install onto your gas meter, right at the point where the meter connects to your home’s gas pipes. In the case of an emergency such as an earthquake, the earthquake shut-off valve closes, restricting gas flow into your home.

Located inside the valve is a metal ball suspended on a ring above the passage where the gas travels though. During an earthquake, the shaking will dislodge this metal ball from its perch. It will fall down into the passage which lies below it and blocks the gas flow. Until you reset the valve, gas cannot enter the pipes in your home. When you reset the valve, what you’re only doing moves the metal ball back into its original position.

If you need earthquake shut-off valves installed or need help resetting your gas valves, do not hesitate. Contact Boss Plumbing today for gas valve services. We’ll be more than happy to come out and install this critical safety device. It often saves lives and can prevent critical earthquake damage following a seismic event.
