4155A 2-Way Temperature Sensing Valve
The 4155 Temperature Sensing Valve monitors liquid temperature in engines and other industrial applications. It can be used as a single component or as part of a complete safety shutdown system for monitoring:
- Jacket water
- Lube oil
- Bearing lube oil temperature
- Gearbox oil

Operation
The temperature sensitive element includes a push rod which rises in response to increasing temperature.
At a predetermined temperature, the valve assembly is lifted from its seating, allowing the sensing medium to vent and reduce pressure within the control circuit.
