The LFC ™_7 energy dissipator is a custom designed piece of equipment that reduces the upstream pressure to the designed ratio at a specific designed flow rate. The LFC™_7 energy dissipator has been developed to present a robust, simple and cost effective method to reduce pressure at a set flow rate in open ended pipes. It will typically be used with a dam level control valve or a column drain valve. The dissipator will ensure that the pressure is discharged from the open end at a safe pressure. The LFC™_7 energy dissipator will increase the life of the valve upstream of it as the valve will not be required to throttle or break pressure. The high wear task is undertaken by the dissipator .
