One Way Valves

One Way Valves


High Performance, light weight, billet aluminium One way valves to suit both Metric and AN/JIC thread fittings of various sizes.  Through research and design we have been able to produce a high quality valve that will both enhance the performance of your fuel system and prolong the life of your fuel pump.

Our anodised AN/JIC one way valves are CNC machined from 6061T6 Aluminium and are Australian made to the SAEJ514 Standard with all threads checked by German thread gauges ensuring that quality and performance is at its best.



By running a Powerflow one way valve, the pressure left between the fuel pump and the fuel regulator after engine shut off will not be able to flow backward through the fuel pump. By preventing this from occurring the strain that would usually be placed on the fuel pumpís internal parts from back pressure is eliminated thus prolonging the fuel pumps life and a costly replacement.


As all one way valves are made right here in Australia Powerflow are able to provide full ongoing support from our team located in Scoresby, Victoria.
