A debris exclusion and removal system for connectors which have a filament barrier configuration designed to clean connectors as they are mated together.

An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

A safety valve device as for use with a compressed gas cylinder and/or a control valve comprising a housing unit, a plug with controlled bleed off channels bored into the plug, an actuator, and an actuating rod, which is designed to engage in the event that a control valve is severed from a compressed gas cylinder, at least partially sealing the opening formed in the compressed gas cylinder from the severing of the control valve, and achieving a safer, controlled bleed off of the compressed gas contained therein.

An emergency release mechanism is applied to fluid loading equipment for transporting fluid, and includes: a pair of pipe portions having a vacuum double structure in each of which a flow path for transporting the fluid is formed, the pair of pipe portions being arranged with opening ends abutting against each other; a coupling member capable of coupling the pair of pipe portions to each other and being removed therefrom; and a pair of shutoff valves configured to shut off the flow path in the pipe portions. The pair of pipe portions respectively include valve seats formed in the flow path. The shutoff valves respectively include valve bodies configured to seat on the respective valve seats to close the flow path, and linear motion drive devices configured to move the respective valve bodies along the flow path to cause the valve bodies to seat on the respective valve seats.
