EDSON
Frequently asked questions
Common questions about EDSON from 3G Electric.
What is the maximum pressure rating for Edson foot valves?
Edson foot valves are rated for a maximum working pressure of 20 psi at 73°F. This rating applies to the bronze-bodied swing-check models with FNPT connections. The valves are designed for low-pressure suction line applications, such as bilge and sump systems, and should not be used in high-pressure or steam service.
What materials are used in Edson suction strainers?
Edson suction strainers feature bronze bodies and strainer elements. The perforations are round and located on the side of the strainer. Bronze provides corrosion resistance in marine and freshwater environments. The strainers are available in 4-inch and 6.6-inch diameters with FNPT female connections.
Are Edson foot valves suitable for saltwater applications?
Yes, Edson foot valves are constructed from bronze, which offers good corrosion resistance in saltwater environments. The valves are commonly used in boat bilge systems and other marine applications. However, the maximum pressure rating of 20 psi at 73°F should be observed, and the valves are not intended for high-pressure or continuous-duty industrial pumping.
What connection types are available for Edson foot valves and suction strainers?
Edson foot valves and suction strainers are available with FNPT (female national pipe taper) connections. The foot valves come in 1 1/2-inch and 2-inch pipe sizes, while the suction strainers are offered in 4-inch and 6.6-inch diameters. All connections are female NPT, allowing direct threading onto male pipe ends.
Can Edson foot valves be used in automotive wash-down sumps?
Yes, Edson offers specific foot valve models (e.g., SKU 49DR57) designed for automotive wash-down sump applications. These valves feature bronze construction and swing-check mechanisms to prevent backflow while allowing full flow. The 20 psi pressure rating is adequate for typical wash-down pump systems.
