摘要

Valve usu00c1vel, apparatus for generating a force to close a set of preventores below the level of the sea and method to retrofit a valve mounted in subchapa is a valve usable in an apparatus below sea level to generate a force to close a set of expected Ntores (BOP) based on a differential pressure between a pressure vessel and low pressure environment.An apparatus which includes the valve and related methods are provided. The valve includes a valve body which surrounds a chamber with a front door selectively attachable to a door and a mounting chamber configured to separate the separation chamber of a region of the pressure different.The assembly includes (1) a backing sheet which has a first portion of a first diameter in the direction of the chamber and a second portion of a second diameter greater than the first diameter in the direction of the region, and (2) a top seat located between the first portion of the plate. The support and the valve body.
