gas meter safety valve brands

Our Safety Relief valves offer an economical installation for large capacity relief applications. And that’s exactly the solution you need when other devices in the system don’t relieve dangerous overpressure in the transmission, distribution and use of gas. Leaking bypass valves can sometimes permit pressure to build during off-peak hours. Pressure regulators with damaged valves or seats are not able to effectively shut off when required, possibly leading to dangerous conditions.

Our mechanical safety relief valves are an economical solution with large relieving capacity. The Model 257-S features a “roll-out” diaphragm with a double-ported single valve in which diaphragm action is constantly matched with spring action. This design offers large capacity, tight seating and reseating, sturdy construction and easy servicing with no adjustments needed.

The RV10 safety relief valve is well-suited for overpressure protection of production equipment, including compressors, scrubbers, separators, pipelines or anywhere overpressure protection may be required.

Sensus safety relief valves offer an economical installation for large capacity relief applications. The Model 250-S and 250-DW valves incorporate a deep molded diaphragm and offer an angled body with a large exit area for a high flow rate.

Relief valves are installed downstream of a pressure reducing regulator and vent excess pressure in case the main regulator fails to close. They are also known as a downstream overpressure protection device, which is required when the internal relief valve of the upstream regulator is inadequate.

Designed to vent directly to atmosphere in outdoor installations, these “pop” style relief valves are economical for high pressures with high flows. Brass construction with a weather cap is standard.

With a variety of sizes and options available, these “pop” style relief valves can be used both outdoors & indoors. Cast iron construction is standard and a weather cap is available.

Designed for installation in stationary ASME applications such as bulk plant, skid tanks, underground and above ground containers as the primary pressure relief valve.

A back pressure regulator designed for a large variety of process applications. Used for any type of industry and ideal for liquids, air as well as gas applications.

Natural gas supply lines are exposed and vulnerable at the meter, and can easily be broken by impact from vehicles, landscape equipment, falling snow and ice, and more-often leading to a catastrophic incident.

When concrete or steel bollards are used to protect gas meter piping from damage, these often only provide nominal protection. In many cases, the bollards are actually the cause of the gas line rupture.

HaloValve is a patented breakaway valve installed to the riser where most breaks occur. Upon impact, HaloValve instantly seals the line, preventing the flow and accumulation of gas until the line can be repaired.

Because of their rigidity, gas risers and associated meter piping can easily break upon impact, causing dangerous leaks. HaloValve creates an intentional weak point in the meter set piping assembly, resulting in an engineered point that instantly self-seals.

Itron relief valves are installed downstream of pressure regulators to relieve limited volumes of gas in industrial, district stations or city gate stations. Used where venting to the atmosphere is acceptable, they provide a cost-effective solution to prevent safety shut-off valves from triggering in case of creep leaks from regulators.

Itron safety relief valves offer robust performances and have been tested by the German Technical and Scientific Association for Gas and Water, Deutscher Verein des Gas (DVGW).

UMW is the sole UK supplier of SRV valves for Itron.  We do appreciate, however, that customers may have alternative requirement which we will try to accommodate where possible.

​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.

To stop the flow of gas into a building during an emergency, turn your gas off at the service shut-off valve. View instructions. Visit Turn Your Gas Off. PG&E installs gas service shut-off valves at all gas meter locations.

Keep a 12- to 15-inch adjustable pipe wrench or crescent wrench available to close the valve in an emergency. Earthquake wrenches with fixed openings may not fit your valve, so an adjustable type is ideal. To minimize the possibility of an unauthorized person tampering with the valve, do not keep wrenches near the gas meter. Shut-off the flow of gas only if you:

To turn off the gas, rotate the valve one-quarter turn in either direction. The valve is closed when the tang (the part on which the wrench is placed) is crosswise to the pipe.

Most gas appliances have a gas shut-off valve located near the appliance that lets you turn off only the gas to that appliance. Find out which of your appliances use gas and where the appliances’ gas shut-off valves are located. In some cases, you need only turn off the gas at the appliance’s shut-off valve.

Some city and county regulations require the installation of automatic gas shut-off devices. This installation may include excess flow gas shut-off valves and/or earthquake-actuated gas shut-off valves. The regulations can vary, but generally apply to:

If a customer installs an excess flow gas shut-off valve or earthquake-actuated gas shut-off valve, the valve must be certified by the State of California. A licensed plumbing contractor must install it according to the manufacturer’s instructions. We do not install or service seismic-actuated or excess flow gas shut-off valves. We do not recommend specific contractors for installation.

Excess flow gas shut-off valves and earthquake-actuated gas shut-off valves must be installed on the building’s gas houseline piping. This pipeline is the gas pipe that connects your appliances to the gas meter downstream of the utility point of delivery. It is located after the PG&E gas shut-off valve, pressure regulator, meter and the service tee. No attachments or connections of any kind are allowed on the utility facilities before the point where the service tee connects to the gas houseline piping. After installation, the valve must not obstruct any gas operations or PG&E services in or around:

The State of California requires approval for all excess flow gas shut-off valves and earthquake-actuated gas shut-off valves used within the state. A list of approved valves is available. Visit DSA Gas Shut-off Valves Certification Program.

A closed gas service shut-off valve or automatic gas shut-off device can delay the restoration of your service by PG&E. Please do not turn the gas on, yourself. Ask a PG&E representative or another qualified professional to perform a safety check, restore gas service and relight your appliance pilots, even if an earthquake did not cause the closure.

1: Close the valve of the main gas pipeline and the gas cooker, open the gas safety valve, and observe the red buoy after 30 minutes. If the original state is maintained, it means that there is no air leakage. If there is a gas leakage problem, it is necessary to proceed to the next step to determine the scope of gas leakage.

2: Close the main gas pipeline valve and safety valve valve, observe the red buoy after 30 minutes, if the red buoy retracts, it means there is air leakage between the gas meter and the safety valve. If the red buoy does not retract, it means the pipeline between the safety valve and the gas cooker is leaking.

Beginning May 2015, Nicor Gas will install a second valve downstream of the meter bar outlet on all new and replacement natural gas service installations. This second valve, known as the Customer Fuel Line Cut Off Valve, will be located at the outlet of the meter bar and will help prevent misuse of the service inlet valve.

The first valve (Nicor Gas’ normal inlet valve) is owned by Nicor Gas. This valve falls under the jurisdiction of 49CFR Part 192.The Nicor Gas Service Valve is to be operated and maintained by Nicor Gas personnel only.

As Nicor Gas’ responsibility for meter sets ends at the outlet of the meter bar; and it is possible that others may have a need to control the flow of natural gas to the customer; the second valve (Customer Fuel Line Cut Off Valve), serves as a non-jurisdictional component of the meter set. Having this component available for operation will allow a qualified HVAC professional to control the flow of natural gas and relight appliances.

Nicor Gas will place tags on all new and replacement natural gas services receiving a Customer Fuel Line Cut Off Valve alerting you that this second valve has been installed and cautioning that only qualified HVAC and plumbing professionals are to operate the Customer Fuel Line Cut Off Valve.
