A shrouded valve assembly comprising a valve with a valve pipe and a valve channel. A valve member in the valve channel is operable to regulate a flow of fluid through the valve channel. A valve shroud shrouds the valve pipe and provides a valve shroud chamber between the valve pipe and the valve shroud. The valve shroud comprises first and second valve shroud members which are fixed to each other via respective valve shroud member flanges. An actuator shaft passes through the valve shroud and the valve pipe to the valve member and can move to operate the valve member to regulate the flow of fluid through the valve channel. The actuator shaft extends in an actuator shaft direction as it passes through the valve shroud and the valve pipe. The valve shroud flanges meet at a valve shroud interface which is inclined at an acute angle to the actuator shaft direction. The actuator shaft passes through the first valve shroud member but not through the second valve shroud member. This enables a simple interface to be provided between the actuator shaft and the first valve shroud member, and also enables the valve to inspected by disassembling this interface without having to disassemble the pair of valve shroud members.
