General

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.

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.
