Honeywell Thermal Solutions FSG L404F1060 Pressure and Limit Controller

The Honeywell FSG L404F1060 Pressure and Limit Controller delivers precise auto-recycle pressure control for steam, air, and non-corrosive fluids. This adjustable subtractive differential controller uses a diaphragm operator for dependable limits in boiler and process applications.

Operating range is 2–5 psi with a 2–6 psi differential, and it accommodates various load profiles. The SPDT two-circuit contact arrangement supports multiple configurations, with ratings for 120 V AC and 240 V AC. Connections are via 1/4" female threads, and mounting can be surface-mounted or threaded for flexible installation. The unit features a clear plastic cover and a gray finish for durable service in challenging environments.

UL and CSA approved, it operates from -35 to 150°F and uses auto-recycle, snap-action switching to respond on pressure rise. Ideal for steam, air, non-combustible gas, or non-corrosive fluid limit control.
