Abstract

A shrouded valve assembly including a valve, valve pipe and valve channel. A valve member can regulate flow of fluid through the valve channel. A valve shroud provides a valve shroud chamber and includes first and second valve shroud members fixed via 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 flow of fluid through the valve channel. The actuator shaft extends in an actuator shaft direction passing through the valve shroud and the valve pipe. The valve shroud flanges meet at a valve shroud interface inclined at an acute angle to the actuator shaft direction. The actuator shaft passes through the first valve shroud member and not the second valve shroud member, enabling the valve to be inspected by disassembling this interface without disassembling the valve shroud members.
