Lyons Filter Co. Flow-Control Units are specifically designed for each application. Our housings are manufactured onsite at our facility ensuring quality. 

The Flow Controllers utilize Griswold Cartridges which have only a single moving part, yet they respond instantly to even the slightest change in system conditions. Within a fraction of a second, they compensate for the surges that can occur when a valve is opened or closed, or when a pump comes on line. Flow is maintained within a broad pressure range at the same rate you have engineered into the system.
