About Bang4buck Fuel Non Return One Way Aluminium Alloy

Check valves are mechanical valves that permit liquids(like fuel, water, oil) to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed. The mechanics of check valve operation are not complicated. And our Bang4buck check valves are made of Aluminum which has much longer using life with very considerable price!
