A temperature relief valve is not something with which I am familiar. I ask an Engineer to comment but it seems to me the only way a valve could relieve temperature would be as a consequence of the reduction of pressure. Ideal Gas Law. So it is just a pressure relief valve: The temperature and pressure relief valve mentioned in the article maybe doesn't exist? Thermostat is to temperature as relief valve is to pressure?? Anyway: please help out here! Psb777 08:30, 30 Jan 2004 (UTC)

  • A google search shows the term to be common. However the context seems to be that "a pressure rise (due to a temperature rise) is vented by the operation of such a valve". Elde 05:41, 1 Feb 2004 (UTC)
    • I had never heard of temperature and pressure relieve valves before (even though I've personally seen safety valves at an oil refinery). Here [1] I found info about one of those. Characteristic is that these valves are equipped with a temperature sensor. Ordinary pressure relief valves open when a preset pressure is reached. Temperature and pressure relieve valves open when a preset pressure is reached. The aim of both types is the same: prevention of overpressure, but the working principle is different.
