Abstract
Concepts and technologies disclosed herein for relief valves ('relief valves'). A relief valve can include a flow path, a primary valve poppet that is urged or biased into a closed position by a tensioned spring, and a pilot valve in communication with a valve compartment of the relief valve. When an exterior space pressure overcomes the tensioned spring, the primary valve poppet can be overcome and pressure between an interior space and the exterior space can equalize, at least partially. When the pressure within the interior space increases beyond a defined threshold, which can be defined by a spring of the pilot valve, the pilot valve can open, the valve compartment can vent, and the tensioned spring again can be overcome and can open to allow at least partial equalization of pressures within the interior space and the exterior space.
