Model LF60 Flo-Clean Strainers are used to filter the fluid pass-

ing through the pilot circuit, and provide protection to pilot circuit 

speed controls and pilots. It is installed in the inlet body port of 

the Main Valve, exposing the strainer element to main line flow. 

The currents and flow across the screen create a self-scouring 

effect, cleaning the filter element.
