Differential Pressure Valve
Model 4143
Overview
AMOT Model 4143 valve is used for sensing loss
of coolant due to hose breakage, poor water
flow due to excessive cavitation or worn pump
impeller blades. Upon a dangerous condition, the
pressure differential will decrease, causing the
valve to vent the lubricating oil pressure supply
line to the AMOT 2800 Master Safety Control,
causing it to trip and shutdown the engine.

Typical applications
lt
Protection of engines and other industrial
equipment in case of water circulation slow
down or failure.
