Abstract
A pressure relief valve (PRV) assembly may include PRV stages coupled in end-to-end relation. Each PRV stage may include a PRV body having a cavity therein to receive an adjacent PRV body therein and a fluid passageway fluidly coupled to the cavity. Each PRV stage may also include a PRV valve carried within the cavity and extending within the fluid passageway, and a first biasing member carried within the cavity to bias the PRV valve. Each PRV stage may further include a biasing member stop coupled to the PRV valve within the fluid passageway, and a second biasing member held within the fluid passageway by the biasing member stop and biasing the PRV valve. An end cap may be coupled to a last PRV stage of the PRV stages to hold the first biasing member within the cavity.
