L404T,V PressureTrol® Controllers are for use on oil burner systems for pressures up to 1035 kPa or 150 psi
FEATURES
• Models available in a series of control ranges, and pressure scales in kPa and psi.
• All models automatically reset and have an adjustable differential.
• Models have snap switch to open or close a circuit on a pressure rise.
• Case has a clear plastic cover so setpoints can be observed.
• 1/4 inch—18 NPT connection for pipe on diaphragm assembly.
• Ground screw terminal.
L404F:
• Controllers may be used with steam, air, or noncombustible gases, or fluids noncorrosive to the pressure sensing element.
L404T:
• High pressure limits, break a circuit on oil pressure rise above setpoint.
L404V:
• Low pressure limits, makes a circuit on oil pressure rise above setpoint.
