The FN-03 and EFN-06/10 adjustable one-way restrictors are designed for applications where fluid oil flow regulation without pressure compensation is required. They can be used whenever the working load remains relatively constant.
Flow regulation is for one direction only. When the flow is reversed the valve opens against a spring and flow passes through at near zero pressure. These valves therefore cannot be used as isolating valves.
