7.3.9 Temperature control valve (2V01)
The temperature control valve maintains desired oil temperature at the engine inlet, by directing
part of the oil flow through the bypass line instead of through the cooler.
When using a temperature control valve with wax elements, the set-point of the valve must
be such that 63°C at the engine inlet is not exceeded. This means that the set-point should
be e.g. 57°C, in which case the valve starts to open at 54°C and at 63°C it is fully open. If
selecting a temperature control valve with wax elements that has a set-point of 63°C, the valve
may not be fully open until the oil temperature is e.g. 68°C, which is too high for the engine
at full load.
A viscosity of 50 cSt at 60°C can be used for evaluation of the pressure drop (SAE 40, VI 95).
