Abstract: The present invention relates to valve apparatus for regulating flow. The apparatus comprises a valve housing having a bore. A piston member (7) is movable within the bore, a first spring member biasing the piston member in a first direction within the bore. A first rod (12) extends through the piston member, the first rod having an end (13) for engaging a second spring member (14) provided between the end (13) and a spring seat (8). The piston member (7) and spring seat define a chamber (9) which houses the second spring member (14) and into which the first rod is slidably received. Further, a second rod extends from the spring seat and is coupled to valve member seat. A damping means is provided to damp the movement of the chamber (9) within the bore.

Abstract: The present invention relates to valve apparatus (1) comprising a valve member (4) moveable for controlling flow through a fluid carrying bore (3). The valve member comprises a valve element (13) coupled to a stem element (5) extending within a stepped stem bore (8) in a stem body, the stem element projecting out from the stem body (2) through a stem bore opening. The valve member is further provided with a pressure-energizable multi-element stem seal (9) within the stem bore, the stem element having a profile which inhibits compete removal of the valve member through the stem bore opening.
