  AMERICAN Ductile Iron Pipe Recognized As A SMaRT Certified Product For Sustainability


The Series 2500 Flex-Ring Gate Valve design incorporates many exclusive design features.

The American−Darling B−84−B−5 hydrant is rated at 250 psig and is seat tested at 500 psig. This hydrant meets or exceeds all requirements of AWWA C502 for dry-barrel hydrants. The all-bronze seat and bronze drain ring assure that the B−84−B−5 hydrant is easily repaired by just one person. The epoxy-primed and polyurethane top-coat system on the external surfaces on the upper barrel of the AMERICAN B-84-B-5 fire hydrant provides a durable, high-gloss finish that, under normal conditions, should continue to look good for years without repainting.

The AFC SEMPER RPM featuring "Lift & Shift" capability is an ideal solution for pressure concerns, fire flow testing, and hydraulic model calibration. 

The AFC SEMPER® RPM featuring "Lift & Shift" capability is an ideal solution for pressure monitoring, transient analysis, fire flow testing, customer pressure concerns, and hydraulic model calibration. This flexible installation method allows the use of a smaller number of units to cover a large area with the advantage allowing utilities to move their RTU’s quickly and easily without having to reconfigure the application or retrofit existing assets. 

The AMERICAN Series 2500 Ductile Iron Resilient Wedge Gate Valve is available with ALPHA ends in sizes 4” -12”. The valve is designed for use in drinking water, sewage and fire protection systems as well as irrigation and backflow control systems.

The American Waterous Pacer’s sleek and stylish design blends perfectly with today’s modern architecture.

The American-Darling B-84-B-5 hydrant incorporates more than 100 years of experience in design, manufacture and field experience.

AMERICAN’s 16"-60" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems.

AMERICAN’s 14"-66" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems.

AMERICAN’s 14"-66" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems.

AMERICAN has combined the Flex-Lok boltless ball joint and the Flex-Ring boltless restrained joint to now provide up to 25 degrees of deflection in sizes 4-inch through 12-inch.

  • Pipe Resiliency In Harsh Environments

    A combination of metallized arc-sprayed zinc coating — with a finishing layer topcoat and V-Bio enhanced polyethylene encasement with an anti-microbial compound and a volatile corrosion inhibitor — uniquely protects pipes in the most aggressive soils.

  • Evolving Advantages For Water Distribution Infrastructure

    With a tried-and-true technology like ductile iron pipe, it can be easy to overlook some of the newer developments that are keeping this long-term water-industry standard relevant in the face of challenging operations. In this conversation with Maury Gaston of American Ductile Iron Pipe/American Spiral Weld and Derek Scott of American Flow Control, the benefits of new opportunities abound.


  • In October 2021, the Birmingham Water Works (BWW) in Birmingham, Alabama, discovered a broken water main in one of its city centers. Read the full case study to see how SEMPER RPM provided critical help.

  • Since the Forsyth County, Georgia, Department of Water and Sewer deployed the AMERICAN Flow Control SEMPER Remote Pressure Monitor (RPM) more than a year ago, it has seen numerous advantages. But the AFC SEMPER’s ability to move from one system asset to another, “Lift and Shift,” is among the greatest.

  • The year was 1989. The place was Anchorage, Alaska. The project was the installation of a gravity sewer line beneath Campbell Lake while it was drained for dam repairs. While this type of project and installation is unique in itself, the pipeline’s performance during a magnitude 7.1 earthquake more than 30 years after it was installed is equally remarkable.

  • The AFC SEMPER RPM featuring "Lift & Shift" capability is an ideal solution for pressure concerns, fire flow testing, and hydraulic model calibration. 

  • Nestled at the foot of the Cerro de Potosí – or Cerro Rico (“rich mountain”) – is Potosí, Bolivia. This capital city of the Tomás Frías Province was established almost 500 years ago and is most known for its abundance of silver, which has fueled the area’s economy for centuries. Another unique aspect of Potosí is its location. It is one of the highest cities in the world, with an elevation of more than 4,000 meters [13,000 feet].

  • Denver Water had four months to replace 2,200 feet of water pipe in an urban setting, in the middle of a colorado winter, and AMERICAN was there to help.

  • In the summer of 2020, the Lowcountry Regional Water System in Hampton, South Carolina, had a customer located in an industrial park report a low water pressure issue. The company was a commercial laundry that served the hospitality industry and provided linens to hotels around the Hilton Head area. The low water pressure issue was causing the company’s heat recovery system to work improperly shortly before the July 4 holiday. In its first use of the AMERICAN Flow Control SEMPER™ Remote Pressure Monitor (RPM), Lowcountry Regional Water System deployed two units to resolve the issue. One device was located on the water system’s side of the meter and the other device was placed inside the company’s building, where water enters the facility at the backflow preventer.

  • For any water system, water hammer, also known as pressure transients, pose significant threats, from leaking joints to service connection failures and even pipes that burst. The damages resulting from these events can be costly to repair and leave customers without water.

  • The Washington County Water Conservancy District was faced with the possibility of a severe water shortage and knew something had to be done. Explore how the solution they chose increased system efficiency and security, while also decreasing treatment and pumping costs. 

  • The Tri-County Water Authority (TCWA) was formed in 1991 as a not-for-profit water utility serving portions of Jackson, Cass and Bates counties, Missouri. When the system was first established, about half of the pipe installed were ductile iron and half were plastic PVC. Today, the authority’s 120 miles of pipe are approximately 75% ductile iron and 25% plastic PVC.


  • Over the past year, the Water Division of the city of Miami Beach, Florida, has seen its use of AMERICAN Flow Control SEMPER Remote Pressure Monitors (RPM) grow. 

  • First, it was Lake Mead, behind Hoover Dam. Now it's Lake Powell, upstream of Mead and behind Glen Canyon Dam. The water supplies supported by these feats of engineering are dwindling. There are many reasons, but it's not necessary.

  • The Lafourche Parish Water District used the AMERICAN Flow Control SEMPER Remote Pressure Monitor (RPM) to understand what was happening to their water system before Hurricane Ida made landfall.

  • I was in fifth grade on the first Earth Day. There was an abandoned earth mover in the woods near my elementary school, and Mrs. Fields’ social studies class painted it with bright colors to improve our visual environment. It was 1970, Richard Nixon was President, and later that year he would establish the Environmental Protection Agency.

    Little did I know then that Earth Day is about science, there are economics within environmentalism, and I would have a career promoting stewardship of the earth.

  • When something goes wrong, we often ask ourselves if there was some sort of sign that would have lessened the impact. Especially if you are in the business of providing water to people, you might wish you had a crystal ball to get in front of problems before they happen. While we can’t provide you with a crystal ball, we can help give some insight into what your water system may be telling you with the introduction of the AFC SEMPER Remote Pressure Monitor.
