About EDSON

Edson International is a US-based manufacturer of marine and industrial fluid-handling equipment, with a product history that dates back to the late 19th century. The company is known for bronze and stainless-steel hardware used in bilge, sump, and pump-suction service. 3G Electric supplies Edson suction strainers and floor-mount foot valves as part of its industrial flow-control catalog, shipping globally to plant engineers, maintenance managers, and procurement teams.

The Edson suction strainer line includes round, side-perforated bronze strainers with female NPT connections. Available sizes in the 3G Electric catalog include 4-inch and 6.6-inch diameters, with corresponding FNPT ports. These strainers are installed on the suction side of positive-displacement and centrifugal pumps to intercept debris before it reaches the pump impeller or valves. The bronze body resists corrosion in fresh-water, bilge, and light chemical service. Perforations are located on the side of the cylindrical body, which allows fluid intake while retaining larger solids. The strainers are typically used with a foot valve or a check valve to maintain prime.

Edson floor-mount foot valves in the 3G Electric catalog are full-flow, inline swing-check designs. They are available with 1-1/2-inch and 2-inch female NPT connections. The valve bodies and strainers are bronze; some variants include a Viton seal. The maximum cold working pressure rating is 20 psi at 73°F. These valves are designed for floor-mount installation in bilge and sump systems, where they hold pump prime and prevent backflow when the pump stops. The swing-check mechanism opens with forward flow and closes when flow reverses. The integrated strainer protects the valve seat from debris.

For technical buyers, the relevant specifications are the connection size and type (FNPT), the strainer diameter, the perforation pattern (round, side-located), the body material (bronze), and the pressure rating (20 psi CWP for the foot valves). The suction strainers do not carry a published pressure rating in the supplied data; they are selected by port size and body diameter. The foot valves are rated for cold water service at 73°F. Viton seals are available on certain 1-1/2-inch models, which extends chemical compatibility beyond standard elastomers.

3G Electric supports the Edson line by stocking multiple SKUs across the suction strainer and foot valve families, providing logistics coordination for global shipments, and offering specification comparison across sizes and seal options. The catalog includes both 4-inch and 6.6-inch strainers, and both 1-1/2-inch and 2-inch foot valves, allowing buyers to match port sizes to existing pump suctions and sump layouts. 3G Electric does not manufacture these products; it distributes them as part of a broader industrial equipment offering.

Common Applications

  • Marine bilge systems — Edson floor-mount foot valve, 1-1/2 in or 2 in FNPT, bronze body, maintains pump prime and prevents backflow.
  • Industrial sump drainage — Edson full-flow foot valve with bronze strainer, 20 psi CWP, installed at the bottom of sump pits.
  • Automotive wash-down sumps — Edson 2 in floor-mount foot valve (SKU 49DR57) for wash-water transfer and debris filtration.
  • Pump suction protection — Edson bronze suction strainer, 4 in or 6.6 in diameter, side-perforated, filters debris before the pump.
  • Water-handling systems — Edson suction strainers and foot valves in bronze, FNPT connections, for fresh-water and light chemical service.
  • Bilge and sump priming — Edson swing-check foot valve with Viton seal (SKU 49DR56), 1-1/2 in FNPT, for chemical-resistant priming.

Frequently asked questions

Common questions about EDSON from 3G Electric.

What sizes of Edson suction strainers does 3G Electric list?

The 3G Electric catalog includes Edson bronze suction strainers in 4-inch and 6.6-inch diameters. The 4-inch models (MPN 11115 and 11120) have 4-inch female NPT connections. The 6.6-inch models (MPN 11130 and 11140) have 6.6-inch female NPT connections. All listed strainers feature round perforations located on the side of the cylindrical body. Selection is typically based on the pump suction port size and the required flow area. The bronze body is suitable for water, bilge, and light chemical service where corrosion resistance is needed.

What is the pressure rating of Edson floor-mount foot valves?

Edson floor-mount foot valves in the 3G Electric catalog are rated to a maximum cold working pressure of 20 psi at 73°F. This rating applies to the 1-1/2-inch and 2-inch full-flow inline swing-check models. The valves are intended for suction-side service in bilge and sump systems, where system pressures are typically low. They are not intended for discharge-side or high-pressure applications. Buyers should verify that the system's maximum operating pressure does not exceed the 20 psi CWP rating at the stated temperature.

What is the difference between the Edson suction strainer and the Edson foot valve?

The Edson suction strainer is a bronze, side-perforated cylinder that attaches to a pump suction line to filter debris. It does not include a check mechanism. The Edson floor-mount foot valve is a full-flow swing-check valve with an integrated bronze strainer. It performs two functions: filtering debris and preventing backflow to maintain pump prime. The foot valve is installed at the bottom of a suction line in a sump or bilge. The suction strainer is used where a separate check valve is already present or where backflow prevention is not required.

Are Viton seals available on Edson foot valves from 3G Electric?

Yes. The 3G Electric catalog includes an Edson floor-mount foot valve with a Viton seal, SKU 49DR56. This model has a 1-1/2-inch FNPT connection, a bronze body and strainer, and a full-flow inline swing-check design. The maximum pressure rating is 20 psi CWP at 73°F. Viton is selected for compatibility with fluids that would degrade standard elastomers, such as certain oils, fuels, and mild chemicals. Buyers should confirm chemical compatibility between the process fluid and Viton before specifying this seal option.

What connection types do Edson suction strainers and foot valves use?

Edson suction strainers and floor-mount foot valves in the 3G Electric catalog use female NPT (FNPT) connections. The suction strainers are available with 4-inch or 6.6-inch FNPT ports. The foot valves are available with 1-1/2-inch or 2-inch FNPT ports. NPT is a tapered pipe thread standard common in North American industrial and marine piping. All connections are female, meaning the mating pipe or fitting must have male NPT threads. Proper thread sealant or tape should be used during installation to prevent leaks on the suction side.

Can Edson foot valves be used in automotive wash-down sumps?

Yes. The 3G Electric catalog lists an Edson floor-mount foot valve (SKU 49DR57) specifically for automotive wash-down sump applications. This model has a 2-inch FNPT connection, a bronze body and strainer, and a full-flow inline swing-check design rated to 20 psi CWP at 73°F. It is installed at the bottom of a sump to maintain pump prime and prevent backflow when the pump is off. The bronze construction resists corrosion from wash water and mild detergents. The integrated strainer helps protect the valve and downstream pump from debris common in wash-down sumps.
