Honeywell Thermal Solutions FSG L91B1068 Pressure Controller

Honeywell FSG L91B1068 Pressure Controller delivers precise differential pressure control for steam, air, gas, and fluids. As a differential-type operator with Prosperous Bronze Bellows, this unit offers reliable modulation across a 10 to 300 PSI operating range and a 325 PSI maximum line pressure, with a differential range of 28 to 110 PSI.

Designed for demanding HVAC and process applications, it supports modulating pressure control on liquids, air, and non-corrosive gases. The 1/4 inch female threaded connection ensures straightforward installation, while the screw-terminal electrical connection simplifies wiring. Approved by UL, CSA, and Swiss RE, this compact controller fits tight spaces with dimensions 4-1/2 Inch Width x 2-3/4 Inch Depth x 6-1/16 Inch Height. The 140-ohm single potentiometer provides precise, stable modulation output.
