The loading station of the invention includes an intake fitting, a pair of pressure operated motorized flow control valves, and a pair of loading boom assemblies that are all mounted on a movable equipment skid. The intake fitting is connectable with a source of high pressure natural gas, and the boom assemblies are universally adjustable and include coupler portions that are connectable with matching coupler portions carried on pressure vessels. Natural gas is loaded into the pressure vessels through the boom assemblies, and the loading station further includes a pressure control system that operates the motorized valves and which prevents natural gas from flowing into the boom assemblies when a pressure vessel is not connected thereto.

A loading station for use in loading natural gas at high pressure from a source thereof into a pressure vessel, the pressure vessel being eqipped with loading manifold apparatus that includes a flow control valve and one portion of a connector device, and said loading station including: an intake fitting arranged to be connected with said source of high pressure natural gas; at least a pair of loading conduit arrangements, each loading conduit arrangement being connected with said intake fitting and including in series moving outwardly therefrom a pressure operated motorized control valve and a one-way check valve arranged to permit flow only in a downstream direction; at least a pair of loading assemblies, one of said assemblies being connected with each of said loading conduit arrangements downstream of the associated one-way check valve, and each of said assemblies including a connector device portion adapted to be connected with said connector device portion of said loading manifold apparatus; and a pressure control system for operating said pressure operated motorized control valves in response to pressurized natural gas transmitted thereto, said pressure control system including a separate control box for each of said loading conduit arrangements, and each of said control boxes containing a pressure control circuit designed and arranged so that its associated motorized control valve cannot receive operating pressure sufficient to open it until the pressurized natural gas transmitted to said pressure control system reaches a pressure value above a pre-set minimum pressure.
