The Tecflow flanged ball check valve is engineered specifically for heavy duty applications in demanding wastewater, sewage and effluent pumping systems. Operating as a highly reliable non-return valve, it features a self-cleaning design where the internal ball rotates during operation to prevent solid matter or stringy waste material from nesting. This ensures consistent, clog-free performance in high solids environments where standard swing check valves frequently fail.
Self-cleaning sinking ball mechanism rotates during flow cycles to clear thick sludge and stringy debris automatically
Bi-directional housing flexibility allows for secure installation in either horizontal or vertical rising pipe networks
Removable bonnet cap allows on-site maintenance crews to clean or replace the internal ball without disconnecting the pipework
A2 stainless steel external bolts and clear direction arrows ensure quick, error-free installation on active sites

The Tecflow flanged ball check valve is a robust non-return solution engineered specifically for high solids fluid management. Unlike standard swing check valves that suffer from premature clogging in sewage and effluent applications, this unit utilises an unrestricted internal chamber. When the pump starts, fluid pressure forces the internal NBR encapsulated ball up and completely out of the flow path, creating a 100% full bore stream with exceptionally low head loss.
The heavy duty valve assembly is manufactured from high tensile GJS500-7 ductile iron, providing excellent structural resilience against systemic shockwaves and fluid surging. To combat aggressive chemicals and rust in buried networks, the casting receives an internal and external 250 micron protective epoxy coating (RAL 5017).
