The shrouded valve assembly (100) comprises a valve with a valve pipe (200) and a valve channel (201). A valve member (220) in the valve channel (201) is operable to regulate a flow of fluid through the valve channel (201). A valve shroud (110, 120) shrouds the valve pipe (200) and provides a valve shroud chamber (240) between the valve pipe (200) and the valve shroud (110, 120). First and second shrouded pipe assemblies are arranged on opposite sides of the valve. Each shrouded pipe assembly comprises a pipe (210a, 210b) which is in fluid communication with a respective end of the valve channel (201), and a pipe shroud (211a, 211b) which shrouds the pipe (210a, 210b) and provides a pipe shroud chamber (212a, 212b) between the pipe (210a, 210b) and the pipe shroud (211a, 211b). Each pipe shroud chamber (212a, 212b) is in fluid communication with a respective end of the valve shroud chamber (240). The first and second shrouded pipe assemblies are connected to the valve shroud (110, 120) by respective first and second connections (410, 420) and to the valve by respective third and fourth connections (430, 440). The fourth connection (440) is more flexible than both the first connection (410) and the second connection (420). As a result load passes between the first and second shrouded pipe assemblies via the valve shroud (110, 120) rather than via the valve, thereby protecting the valve from damage.
