This is the mechanism by which the pressure relief valve allows excessive pressure to escape. If you find that your water heater regularly leaks water in this way, you may need to replace the thermostat, or turn it down to a more suitable temperature. What It Does During times of ...
So the choice between a pressure control valve and a flow control valve depends on the specific application requirements, with pressure control valves used to maintain a constant pressure and flow control valves used to regulate the volume of fluid/gas passing through a system over a specific pe...

It is held closed by pressure from the valve outlet, and opens under pressure from the inlet. Beyond these most basic principles, a number of other factors come into play, most notably, actuation. In other words, the force or mechanism that makes the valve open, close, or do whatever ...
pressure relief valve Operation In operation, pressure relief valves exhibit precision in responding to pressure increase, ensuring that pressure does not exceed set limits. When the system pressure reaches a critical point, these valves open to release excess pressure, averting potential damage and cat...
What is a breather valve, exactly? A breather valve, also known as a pressure relief valve, prevents excessive pressure or vacuum buildup in a sealed container, enclosure, or other sealed space. AGM carries two variations of breather valves in a variety of sizes: Spring-actuated breather valve...

If I understand your question right, the answer is no, the vessel does not need to be stamped due to (presumably) having less than 15 psig design pressure. You have done a quick HAZOP and determined that the vessel, while normally operating at less than 10 psig, can not ever see more...
There is a large difference between a pressure relief valve and a thermal relief valve, as the name suggests! Although they can be combined into one valve, a thermal valve will operate at a preset temperature regardless of pressure to discharge the hot fluid, introduce a cooling supply, or ...
