FR20 Reversing Valves operate in conjunction with two pressure switches, alternating lubricant flow through DC41 end-of-line systems so that lubricant is directed first to one set of Dualine valve inlet ports and then the other, on succeeding system cycles.
Each coil has a power-on indicating light located on the terminal box. This is very helpful when troubleshooting a system.
Plug-in coils are easily changed without disturbing the wiring.
The new FR20 is completely interchangeable with existing FR10.
