The Peak Flow-Activated Safety Valve (FASV) is a cost effective, insert safety device that can be run below any suitable lock mandrel or nippleless SIM retrieveable bridge plug.

Used when surface communication is no longer available between the surface control panel and the tubing retrievable surface controlled subsurface safety valve (TRSCSSV).

A pressure safety valve actuated by inlet static pressure and characterized by rapid opening or rapid popping action. This safety valve is tight shut-off and is for safety only. Meets ASME SEC. VIII (Not a Fulflo valve)

A spring loaded pressure relief valve, actuated by the static pressure upstream of the valve. The valve opens normally in proportion to the increase in pressure over the set pressure. (Fulflo)

A pressure relief valve characterized by rapid opening or pop-action in direct proportion to the pressure increase, depending on the application. (Fulflo)

The pressure existing at the outlet of a pressure relief valve, due to the pressure in the discharge system. The pressure can be constant or variable. It is the sum of the superimposed and build-up pressure.

Fulflo was established in 1912 and is celebrating its 100th anniversary. Located in Blanchester, OH, Fulflo was incorporated in 1933 under its present name and trademark. Patents for the original guided piston, direct acting relief valve were obtained in 1935, coinciding with the onset of fluid power systems. The need for providing large flows without excessive bulk was met by the pilot-valve-control relief valve which was patented in 1943.

Fulflo parts and valves are used in oil and gas refineries, are essential to the military, including ships and aircraft carriers, and amusement roller coaster rides.

Automatically shuts off air flow upon a sudden air line break. Protects plant personnel and property from injury by "whipping" air hoses. Resets when repair is made. Allows full, unrestricted flow of air in normal open position. Meets OSHA Standard 1926.302(b)(7) for air hoses exceeding 1/2" ID requiring a safety device at the source of supply or branch line to reduce pressure in case of hose failure.

Designed to automatically shut off air flow in the event of a sudden break in an air line, these valves allow for full unrestricted flow while in the normal (open) position. This unit will reset itself once the repair in the air line is made. Consult with Coilhose customer service department for application information.

An important tool for determining field performance, Honeywell Gas Depot offers both digital and analog differential pressure testers to measure pressure drop across meters, filters, valves, and other gas system components.

BrassCraft’s Safety+PLUS gas connector combines patented excess flow technology with the advanced corrosion resistance, to provide a safer gas connector for your home and family. In the event of a gas line rupture or disconnect, the Safety+PLUS Excess Flow Valve (EFV) restricts gas flow at the appliance to a non-hazardous level. This immediate action helps avert the potential for a dangerous release of gas into the home. Gas is controlled only at the point where the problem exists; the rest of your system will continue to function. Safety+PLUS EFV automatically resets once the gas line is properly repaired. BrassCraft’s stainless steel gas connector also features a proprietary polymer coating designed to withstand prolonged exposure to harsh household cleaning, plumbing repair and masonry products as well as UV rays and salt. Unlike conventional dipped or sprayed coatings, the ProCoat coating is baked directly on the connector surface at high temperatures to provide a uniform coating over the entire length of the connector. The coating is applied only after the connector has been 100% leak tested to provide the most complete corrosion resistance.

The SI2 safety valve prevents the allowed operating pressure from being exceeded by more than 10%. If, after opening, the adjusted response pressure falls below max. 10% (gases) and max. 20 % (liquids), the valve closes.

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

important to understand that an EFV does not shut off the flow of natural gas completely. Some leakage may still occur resulting in a hazardous condition.
