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.

L404F:
PRODUCT DATA
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
systems for pressures up to 1035 kPa or 150 psi.
Controllers are for use on oil burner
• 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.

Pressure Sensing Element: Stainless steel diaphragm (140
to 2070 kPa models) has brass bellows.
Maximum Ambient Temperature: 66°C (150°F). Also, refer
to note under Mounting.
Adjustment Means: Screws on top of control case. Scales are
marked in psi or kPa.
Mounting Means: 1/4 inch-18 NPT connection on diaphragm
assembly; or surface mounts using holes in back of case.
Dimensions: See Fig. 1.
Switching Action: Snap switch breaks R-B (closes R-W) on
pressure rise. Make-on-rise devices omit terminal B.
Grounding Means: Ground screw terminal marked with a
circled ground symbol.
