The R-400 is a modulating float pilot with a plastic float, suitable for remote installation on a tank or reservoir.
It positions the main valve in proportion to the reservoir level. Standard configuration is for the pilot to close on rising level. Specify “Reverse Acting” for the pilot to open on rising level. The polypropylene float connects to the pilot on a 10 in / 250 mm brass rod.
The R-400 pilot is used as the standard float pilot on all 106 and 206 series modulating float valves.
