Abstract: 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).

Abstract: The invention relates to a valve assembly that can be provided of a length to meet conventional fitting dimensions and requirements. The valve assembly includes a valve body housing, at least first and second valve balls. Between the first and second valve balls are provided first and second valve seats. The valve seats are biased towards their respective valve balls by common biasing means. The valve seats, that lie between the valve balls, are typically provided as part of a common valve seat assembly that includes the biasing means.

Abstract: The invention relates to a valve assembly which includes at least one, but typically two, balls (12,14) located along a passage and which balls can be moved between open and closed positions to selectively control the passage of fluid along the passage. The valve assembly includes at at least one end thereof a retaining assembly (32,34) which allows the effective sealing against one surface of a ball and retention of the same in position. A sealing assembly is also provided when two balls are provided, intermediate the same, which allows effective sealing to be achieved and at least one of the two trunnions which allows each of the balls to be mounted within the valve body is located only internally of the valve body. The components of the valve assembly which are located within the same can in one embodiment all be inserted into and located within the valve body from one common end.
