Honeywell L404 Pressuretrol® Pressure Limiting Controllers

Honeywell's L404F Pressuretrol is an operating control with automatic limit protection for pressure systems up to 300 PSI. You can use it with steam, air, noncombustible gases, or fluids that are not corrosive to the pressure sensing element.

All Pressuretrol models feature automatic reset with adjustable differentials.

 

  • For use with steam, air, non-combustible gases, or fluids non-corrosive to sensing elements
  • SPDT snap action switches to open or close a circuit on pressure rise
  • 120 VAC switch rating: 8.0 AFL, 48.0 ALR, 10.0 Amp resistive
  • Adjustments are made by screws on top of the case
  • Clear plastic cover on the case make setpoints easy to see
  • Mount using 1/4"-18 NPT internal pipe threads, or surface mount through the base of the case
