Excess Flow Valve Devices
An An excess flow valve is a mechanical device installed inside a natural gas distribution service line between the street and residential meter that enhances the safety of your natural gas service. If there is a significant increase in the flow of gas (e.g., due to a damaged line), the EFV will “trip” or close to minimize the flow of gas through the service line. EFVs do not stop the flow of gas for any leaks or faulty equipment on the customer’s side of the gas meter. Once the repair is made and the correct pressure is restored, the EFV automatically resets itself.
We install EFVs on all new services where the system operating pressure is appropriate, and many customers on our system already have the devices in place.However, EFVs will not work properly on all natural gas services, which means not all customers qualify for an EFV.
If you are interested in having an EFV installed on your gas service line, or to see if you already have an EFV installed at your location, please contact Valley Energy at 570-888-9664 or 800-998-4427.
If there is not an EFV on your existing service line and your service pressure is compatible with proper operation of an EFV, we will install the device on your line at your request. Generally, the cost to the customer to have Valley Energy install an excess flow valve on an existing line ranges from $800 to $1,500. The process of installing the EFV requires excavating to expose the gas service line where it connects to the natural gas main. While the work typically takes no more than one day, restoration of the excavation site may take longer. Since an excess flow valve must be sized to operate properly under current load conditions, any significant load changes that would require a larger meter, such as installing an emergency generator or pool heater, may also require the replacement of the EFV at an additional cost.
