OPERATION
The BWB "PH" is a 3 way, dual pilot, automatic relay. It is normally installed near a pump, a control valve, or
inside a control panel. It receives dual instrument pressures (Ports D & E) from safety system controllers for
process levels or valves.
When instrument pressure (Port E) is applied, it will automatically push the relay into the closed position.
The inlet (Port B) is blocked and the outlet (Port C) is open to the exhaust (Port A). The relay will remain in the
closed position when instrument pressure (Port E) is lost.
