A valve is provided for use in a fluid flow line with first and second parts connectable to define a fluid flow path through the valve. A first valve member is operable in the first part and a second valve member is operable in the second part, and the valve members are arranged for movement between an open position and a closed position for shutting off fluid flow. The valve includes a closure mechanism for activating movement of the valve members from the open position to the closed position, and a separation mechanism for allowing the first and second parts of the valve to separate from one another. The valve has a fluid transfer mode of operation and a separation mode of operation. In the fluid transfer mode of operation, the first and second parts of the valve are connected together, the first and second valve members are in an open position and fluid can flow along the flow path through the valve. In the separation mode of operation, the separation mechanism is operable to separate the first and second parts of the valve, after operation of the closure mechanism. |
