Weflo FFA-5400F-DCDA Double Check Detector Assembly – Backflow Prevention with Flow Monitoring
The Weflo FFA-5400F-DCDA Double Check Detector Assembly is a reliable backflow prevention device designed to protect water systems by preventing reverse flow while providing monitoring of low-volume water usage. It combines a double check valve assembly with a bypass detector arrangement to help identify unauthorized or continuous water draw-off.
Designed for commercial, industrial, and water distribution applications, the FFA-5400F-DCDA features a robust flanged connection configuration for secure installation in larger piping systems. The integrated bypass line with water meter provides additional flow monitoring capability, making it suitable for applications where both backflow protection and system monitoring are required.
The assembly supports dependable operation in cold water service environments and is designed for use where controlled water flow protection is required.
