Pressure Switches

Pressure and Vacuum Switches will incorporate a U.L. Listed Single Pole double throw snap-action micro switch. The switch enclosure will have a NEMA 4 water tight housing with a mounting bracket. Electrical ratings will be 10 amps at 120 volt AC. Only for Nitrogen and Instrument Air will 2 switches be required. Pressure and Vacuum switches with gauges will incorporate a 2″ dial after the pressure switch.

Pressure:

  • Tested at 160 psi with an adjustable range of .5 to 80 psi
  • Settings will be 40 psi and 60 psi for pressure gases

Vacuum:

  • Tested up to 30″ Hg with an adjustable range of .8″ to 29″
  • Preset at 12″ Hg for alarm condition

Instrument Air, Nitrogen & Reserve Switches:

  • Proof Pressure of 1000 psi
  • Adjustable range of 10 to 230 psi decreasing pressure or 11 to 250 psi increasing pressure

Reserve Manifold:

  • Preset to 1,100 psi decreasing pressure
