Abstract

A shrouded valve assembly includes a valve with a valve pipe and a valve channel. A valve member in the valve channel can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber. First and second shrouded pipe assemblies are on opposite sides of the valve, each including a pipe in fluid communication with a respective end of the valve channel, and a pipe shroud providing a pipe shroud chamber. Each pipe shroud chamber is in fluid communication with a respective end of the valve shroud chamber. The pipe assemblies are connected to the valve shroud by first and second connections and to the valve by third and fourth connections, the fourth connection more flexible than both the first connection and the second connection. Load passes between the pipe assemblies via the valve shroud rather than via the valve, protecting the valve from damage.
