1100 Series Liquid Flow Switch

Description

Our model 1100 series is an Industrial Standard that sets the bar for other units to be ranked against. True globe shaped housings yielding lower pressure drops, one-piece cast bodies to achieve pressure capabilities unheard of in the industry, among other reasons as to why our units are the standard to compare others to.

You’ll find these units commonly in the HVAC, Machine Tool, and Marine industries, but you will find them other places too due to their reliability and accuracy.

This model offers field-replaceable bonnet assemblies featuring a “Clean-In-Place” approach; no need to un-plumb/ remove the body from the line, simply de-pressurize the line, remove the nut, and pull the bonnet assembly out; reverse the process to get your system back up and running!

Note: Also available in SST, 1″ FNPT, 1.5″ FNPT, 2 GPM | 4 GPM | 5 GPM | 10 GPM | 15 GPM | 26 GPM | 35 GPM | 50 GPM
