<p>The invention relates to a valve assembly (1), typically of the double block and bleed type. Conventionally these assemblies include a flange formation at each end to allow the same to be joined to adjacent pipeline end flanges. However this causes problems as there are limitations on the acceptable length of these valve types. The present invention provides ports (34) for the reception of location means (32) in the valve body (2) without the need for the flange formations and therefor allows the valve body (2) to extend along the whole length of the valve assembly (1), increasing the space available for the valve components within the valve assembly (1).</p> |
