ABSTRACT:
A safety valve assembly for use with a global manual valve which is installed on a high pressure cylinder or container. The safety valve assembly has a main body that is threaded into the lower bore of the global manual valve. A poppet valve slides into the bore of the main body and is restrained by a valve seat. An end cap is then threaded into the lower end of the main body to keep the poppet valve inside. The poppet valve has longitudinal flutes formed on the surface for regulated passage of gases and fluids. The poppet valve also has a cone on the upper end, which can have bleeder veins inscribed on its surface. When activated, the poppet valve prevents the uncontrolled release of high pressure out of the cylinder. Thereafter, the bleeder veins permit the release of small amounts of high pressure until the cylinder is exhausted to a safe level.
