4143 DIFFERENTIAL PRESSURE VALVE
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 AMOTÂ 2800 Master Safety Control, causing it to trip and shutdown the engine.
Model 4143 senses the pressure differential between each side of the water pumps. Valve port stamped P2 is piped to water pump discharge and valve port stamped P1 is piped to water pump suction. As the dangerous condition arises, the pressure differential will decrease and the valve will vent the lubricating oil pressure supply causing it to trip and shut down the engine.
