This clearly suggests that the thermostat does, indeed, control the temperature by the amount it is open, not that the temp is controlled by an "OFF and ON" cycle. | This clearly suggests that the thermostat does, indeed, control the temperature by the amount it is open, not that the temp is controlled by an "OFF and ON" cycle. | ||

Previously, it was erroneously suggested that a "true" industrial valve would behave differently than an automotive thermostat, that an automotive thermostat could only control the coolant temp in one direction and that an industrial valve would be in a "centered" position at "normal" temps so it can both increase AND decrease the coolant temp. | Previously, it was erroneously suggested that a "true" industrial valve would behave differently than an automotive thermostat, that an automotive thermostat could only control the coolant temp in one direction and that an industrial valve would be in a "centered" position at "normal" temps so it can both increase AND decrease the coolant temp. |
