Abstract
A vacuum relief assembly for a containment vessel. The vacuum relief assembly includes a normally closed pressure activated valve assembly that selectively permits flow into the containment vessel from the atmosphere through an interior passage. The valve body includes inlet opening into the interior passage. It also includes a torque acceptance portion to permit connection of the valve assembly to a vessel. A tamper resistant cap is secured in overlying relation to the inlet opening and the torque acceptance portion. The cap is secured with mechanism that provides indicia of tampering.
