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.
Features and Benefits
- Coolant loss
- Excessive aeration
- Worn pump impeller blades
