Pressure Control 10 - 150 psi Operating 10-22 psi Differential

Resideo PA404A is a pressure actuated high limit, safety control for steam heating boilers. It breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level.

The PA404B is used with suspension-type unit heaters to make the fan circuit when a pressure rise indicates the presence of steam.

Each model contains an SPST MICRO SWITCH snap-acting switch.Sensitive pressure-actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch.

A screw on top of the case allows set point adjustment without removing the cover.Differential is adjusted by means of a dial located inside the case..,
