An internal valve includes a valve stem disposed in a valve body, a poppet valve coupled to the stem, and a bleed valve coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and the poppet may close in response to a pressure change. The internal valve includes a strainer having an extended portion to be positioned in a clearance space between an upper portion of the valve body and an opening of a fluid container. The strainer is arranged for securement to a mounting area of the valve body by at least one fastener.

The valve body includes a shoulder that is arranged for sealing engagement with a container flange and is between an inlet and a flange of the valve body and spaced away from the inlet. The shoulder is arranged on the valve body to place the inlet a desired distance away from the inner wall of the fluid container.

One embodiment is related to a valve apparatus to be mounted on a fuel tank. The valve apparatus including: a housing including a ventilation chamber on a bottom face of which a first opening and a second opening are provided, and a valve chamber communicating with the first opening and disposed below the ventilation chamber, and a float valve disposed in the valve chamber. The housing includes a canister-connecting pipe communicating with the second opening. A standing wall is disposed on the bottom face of the ventilation chamber between a peripheral edge portion of the first opening and a peripheral edge portion of the second opening. And, an overhang wall portion extends from a side face of the standing wall toward the first opening, as viewed from above.

A tanker railroad car with one or more non-contact sensing assemblies that are configured to sense a level of fluid in a tanker railroad car using one or more non-contact sensors, wherein the non-contact sensing assemblies are configured to communicate with a converter device that translates output signals from the non-contact sensors into readings of the level of fluid in the tanker railroad car in desired output units.

A drain valve for a portable tank has a flange securable externally to a wall of the tank and formed with a hole centered on a flange axis perpendicular to a face of the flange. A housing extends from the flange and forms a housing flow passage extending along a passage axis opening into the tank at the hole of the flange and forming an angle of less than 90 with the flange axis. A ball valve element in the housing at the housing flow passage is movable between an open position permitting flow through the housing flow passage and a closed position blocking such flow. A shaft journaled in the housing is fixed to the ball valve element and extends along a shaft axis substantially perpendicular to the passage axis. An actuator connected to the shaft outside the housing is operable to pivot the ball valve element about the shaft axis between the open and closed positions.

Actuator for a valve, comprising a first piston, a first piston rod and a first fluid chamber for enabling movement of the first piston and the first piston rod. The actuator has a second piston, a second piston rod, the second piston rod being coaxially arranged with the first piston rod and radially enclosing at least a part of the first piston rod. A second fluid chamber is arranged for the second piston, for enabling movement of the second piston and the second piston rod. A first fluid channel is arranged in communication with each of the first and the second fluid chambers, for effecting, when fluid is introduced into the first fluid channel, movement of the first piston and the second piston. Also, a valve comprising such actuator is disclosed.

A fluid container designed for filling through an opening in a bottom surface. The fluid container includes a connection device, including a ring crimped around the opening and a cap. The ring may include a ferrous metal. The cap may include a magnetic material. The cap may be removable from the fluid container. The cap is coupled to the ring via magnetic attraction to seal the opening in the bottom surface in a fluid container closed position. The connection device is designed to transition from the fluid container closed position to a fluid container open position when the connection device is coupled to a filling device for filling of the fluid container.
