Series AGB Silent Check Valves



CheckFlo provides a range of Silent Check and Nozzle Check Valves that prevent Water Hammer and reverse flow and insure long and trouble free operation.

Each check valve in our range balances the capital cost with ease of installation and performance to provide an optimum solution to the end user.

CheckFlo Check Valves were designed utilising the latest in Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) software. Each validated design was heavily prototyped and refined followed by independent flow and hydrostatic testing. This has resulted in a light weight moving assembly with excellent flow and dynamic characteristics for each design type. The result is that CheckFlo Check Valves provides the best combination of flow efficiency and excellent dynamic response in comparison to any conventional check valve design.
