PRODUCT DATA
FEATURES
APPLICATION
L404F PressureTrol® Controllers provide operating control with automatic limit protection for pressure systems of up to 2070 kPa, or 300 psi.
L404T,V PressureTrol® Controllers are for use on oil burner systems for pressures up to 1035 kPa or 150 psi.
•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 
•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.
