A valve, and tubular cage component for a valve, in which the tubular cage is formed such that at least a ported portion between the ends of the cage includes a tubular outer cage member formed from a metal material, and a tubular inner cage member formed from a wear resistant material. The inner cage member and the outer cage member are concentrically aligned and have a length to span at least the ported portion. Some or all of the flow ports in the ported portion include a port insert which includes a port sleeve formed from a wear resistant material such that the port sleeve extends at least over the metal material of the outer cage member at the flow port.

A removable independent steam jacket for a bottom outlet valve of a railroad tank car able to connect to an existing bottom outlet valve, with or without an integral steam jacket, in a field environment without having to take the tank car in for repairs having a partially annular hollow base with a rectangular cross-section and a plurality of pipes connected to the base extending away from the bottom of the base. The removable steam jacket also has a plurality of mounting brackets connected to the bottom the base for installing and removing it from the bottom outlet valve.

A pressurized gas containing system has a cowling and mounting ring which supports a valve and regulator on a cylinder containing gas under pressure.

An apparatus is provided for protecting from freezing an above-ground conduit outlet on an exterior wall of a building, the freeze protection apparatus comprising a housing including a top wall, a front wall, and a pair of opposed side walls interconnecting the top wall and the front wall. The housing partially defines an enclosed area having a rear aperture and a bottom aperture. Thermal insulating material lines the interior surface of the walls of the housing. Means are provided for mounting the housing to the exterior wall adjacent the conduit outlet. The inner edges of the side walls and the top wall contact the exterior wall and the bottom edges of the side walls and the front wall contact the ground for enclosing the conduit outlet. Heat is retained within the housing to prevent fluid within the conduit from freezing.

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.

Exemplary embodiments are directed to a pipe valve insulation cover. The cover includes a flexible sheet including a first side and a second side positioned over each other in a substantially overlapping manner. In the overlapping configuration, the flexible sheet defines a top edge, a bottom edge opposing the top edge, a right edge, and a left edge opposing the right edge. The flexible sheet defines a hollow interior in the overlapping configuration. The cover includes a first opening formed in the flexible sheet at or near the top edge, a second opening formed in the flexible sheet at or near the right edge, a third opening formed in the flexible sheet at or near the left edge, and a fourth opening formed in the flexible sheet at or near the bottom edge.

A system for semiconductor fabrication having at least one heated valve manifold assembly comprising a heat-conductive plate having a total surface area, said conductive plate having a first side and a second side; at least one heater contacting said at least one heat-conductive plate; a valve manifold comprising a plurality of valves and pipes; said plurality of said valves and pipes having a total surface area wherein a portion of the surface area of said plurality of valves and pipes contacts said at least one heat-conductive plate; and one or more layers of insulation covering: (i) a majority of the surface area of said plurality of said valves and pipes where said portion contacts said at least one heat-conductive plate, (ii) said at least one heater in contact with said at least one heat-conductive plate, and (iii) the majority of the surface area of said at least one heat-conductive plate.
