A valve, comprising: a housing defining a flow path for a liquid between a fluid inlet and a fluid outlet, the housing having a first and a second hole formed therein, the first and second holes forming part of the flow path; a plug movable in relation to the housing between a first position in which the plug blocks the first hole to create a normal operational flow rate of liquid between the fluid inlet and the fluid outlet and a second position in which the plug does not block the first hole to create a purging flow rate of liquid between the fluid inlet and the fluid outlet, the purging flow rate larger than the normal operational flow rate; and an actuator that moves the plug from the second position to the first position when the temperature of the fluid is at or above a predetermined level.
