A valve arrangement for a hose end coupler of a transfer hose for the offloading of hydrocarbons from an offshore floating production storage and offloading vessel (FPSO) to a shuttle tanker is described. The valve arrangement comprises a linear valve comprising a linear valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; a secondary valve comprising a secondary valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; wherein the linear valve actuator and the secondary valve actuator are operatively coupled such that movement of the linear valve actuator between the first position and the second position effects a corresponding movement of the secondary valve actuator between the first position and the second position. A hose end coupler with such a valve arrangement, and a transfer hose and transfer system and method incorporating such a hose end coupler with such a valve arrangement are also described.

To provide a safety joint that can immediately shut off a hydrogen gas flow path at the initial stage when a plug (nozzle side member) comes out of a socket (fueling apparatus side member) to prevent release of hydrogen gas. In a safety joint (100, 100-1, 100-2) when the plug (10) is disconnected from the socket (20), a plug side shutoff valve 5 and a socket side shutoff valve 24 close, a mechanism for closing the socket side shutoff valve (24) includes a socket side spring (23) for urging a socket side valve body (25), a socket side rod (22) connected to the socket side valve body (25), and a support member (26, 27, 28) for supporting (mounting) the socket side rod (22), the support member (26, 27, 28) moves, together with the plug (10), to a state that the support member (26, 27, 28) does not support (mount) the socket side rod (22) when the plug (10) is disconnected from the socket (20).

To provide a safety joint that can immediately shut off a hydrogen gas flow path at the initial stage when a plug (nozzle side member) comes out of a socket (fueling apparatus side member) to prevent release of outgas. A safety joint (100, 100-1) of the present invention includes: a plug (10) with a flow path (1A) formed inside, a shutoff valve (5) of the plug (10) opens when connected to a socket (20); and the socket (20), a flow path (21A) in communication with the flow path (1A) is formed when connected to the plug (10); and when the plug (10) is disconnected from the socket (20), the flow paths (1A, 21A) of the plug (10) and the socket (20) are shut off, wherein the socket has an opening (21C) that communicates with the flow path (21A) and extends orthogonally to the flow path (21A); when the plug and the socket are connected, a protruding portion (3) of the plug is inserted into the opening; and a socket flow path blocking mechanism (30, 31) is provided to instantly close the flow path (21A) at an initial stage when the plug is disconnected from the socket.

An automatic shutoff valve for breakaway wet barrel fire hydrant is disclosed. In general, one aspect disclosed features an apparatus comprising: a valve housing comprising a valve body, a flange, and a valve seat; a valve pedal configured to engage the valve seat and prevent fluid flow through the valve seat in a closed position, and to permit fluid flow through the valve seat in an open position; a lockout tab disposed within the valve body, wherein the lockout tab maintains the valve pedal in the open position; a lockout bar disposed distally from the valve body; and an activation rod mechanically coupled to the lockout bar and configured to keep the valve pedal engaged with the lockout tab.

A check valve includes a valve body defining a valve bore extending from a first axial end to a second axial end, the valve body including an annular body and a cross member secured to and extending across the valve bore from the annular body on one side of the valve body to the annular body on an opposite side of the valve body, the valve bore at the cross member divided into more than one portion by the cross member; a position block extending from the cross member; a valve member positioned within the valve body and configured to rotate between an open position and a closed position; and a pivot pin extending from the valve member, engaged with the position block, and fixed with respect to the valve member; the valve member and the pivot pin configured to rotate together between the open position and the closed position.

A check valve can include a valve body defining a valve bore, the valve body comprising an annular body and a cross member secured to and extending in a radial direction across the valve bore from the annular body on one side of the valve body to the annular body on an opposite side of the valve body, the valve bore at the cross member divided into more than one portion by the cross member; a position block extending from the cross member; a pair of valve members, each valve member of the pair of valve members positioned within the valve body and configured to rotate between open and closed positions; and a pivot pin positioned within the valve body and extending through the position block and each valve member of the pair of valve members, the pivot pin being supported only by the position block.

A first tubular and a second tubular define a fluid passage. A feather is positioned within the first tubular. The feather is configured to axially translate towards the second tubular and pivot towards a center of the first tubular. The feather includes a hinge on a pivoting end. A first end of a spring is coupled to the feather and a second end of the spring is coupled to the first tubular. The spring is loaded to actuate a movement of the feather between an open position and a closed position. A trigger is positioned between the first tubular and the second tubular to provide an interference with the feather. The interference retains the feather in the open position when the first tubular and second tubular are coupled.

A check valve for a fluid distribution system can include a valve body defining a valve inner cavity defining a valve bore extending from a first axial end to a second axial end; a position block secured to the valve body and defining a pivot bore; a pivot pin positioned within the valve body and extending through the pivot bore of the position block; and a valve member positioned within the valve body and configured to rotate about the pivot pin from an open position to a closed position, the valve member configured to remain in the open position as long as a fluid in the fluid distribution system is moving in a positive flow direction of the check valve, the valve member further configured to close when the fluid is moving in a negative flow direction of the check valve.

A coupling for a break-away valve assembly includes a coupling and an adapter, the coupling including: a valve arranged in an annular body, the annular body having a valve seat including a first portion and a second portion, adjacent to the first portion, of greater internal diameter relative to the first portion, the valve being biased in a first direction to seal against the valve seat on disconnection of the coupling from the adapter, wherein the valve is biased in a second direction, and the valve is adapted to extend past the first portion into the second portion of the valve seat to release a volume of fluid if the pressure acting on the valve exceeds a predetermined surge pressure threshold.
