L404T,V PressureTrol® Controllers are for use on oil burner systems for pressures up to 1035 kPa or 150 psi. PRODUCT DATA FEATURES • Models available in a series of control ranges, and pressure scales in kPa and psi. • All models automatically reset and have an adjustabledifferential. • Models have snap switch to open or close a circuit ona pressure rise. • Case has a clear plastic cover so setpoints can beobserved. • 1/4 inch—18 NPT connection for pipe on diaphragm assembly. • Ground screw terminal. L404F: • Controllers may be used with steam, air, ornoncombustible 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 pressurerise above setpoint.
