Emergency response transfer valve

摘要

An emergency transfer valve (10) attaches to a transportable tank (403) and allows an operator to actuate a valve stem (22) that will open a check valve (404) that prevents the tank (430) from leaking if the tank dome (401) and valves (10) are sheared off. The transfer valve (10) includes a valve stem (22) that engages and unseats a check valve plug (414) and has an outlet port (33) that allows a transfer line to be attached thereto to facilitate loading and unloading of the tank (430).
