摘要:
A valve assembly comprises a valve (22) including a valve body (24) and a movable valve closure member (26). The valve assembly also includes a manifold (12) having a bore (20) with a valve opening through which the valve (22) is received into the bore (20), and at least one process fluid pathway defined within the manifold (12) in fluid communication with the bore (20). The valve (22) includes a proximal end section arranged to close the valve opening (23) and an opposing distal end located within the bore (20) inwardly of the proximal end. The valve closure member (34) is arranged to open and close the at least one fluid pathway. In addition a primary seal is located between the valve body (24) and the manifold (12) to seal the valve opening (23), with a secondary seal being located inwardly of the primary seal along the bore (20) relative to the valve opening (23) arranged to create a seal between and the valve body (24) and the bore (20) to isolate the primary seal from the first fluid pathway. The valve assembly further includes a vent port (74) in fluid communication with the bore (20) located along the bore (20) between the primary seal and the secondary seal.
