  "textContent": "A pressure actuated valve assembly includes a valve body. The downstream end portion of a main spring (106) is engaged with a downstream end portion of the valve body and the main spring is axially aligned with the valve body. A main spring guide (110) is engaged with an upstream end portion of the main spring (106) proximate an upstream end portion of the valve body. The main spring guide (110) is mounted for movement toward the downstream end portion of the valve body by compression of the main spring. A hold-down sleeve (116) is engaged with the downstream end portion of the valve body and includes a stop structure proximate the main spring guide. The stop structure is configured to engage the main spring guide (110) to maintain a predetermined minimum clearance between the main spring guide and the upstream end portion of the valve body with the valve body in the closed condition.",
