A liquid collection and evaporation device is proposed for use between a cooling water regulating valve of a vehicle and an actuator device for actuating the valve. The liquid collection and evaporation device includes a separation tank for collecting and evaporating liquid droplets emerging from the cooling water regulating valve. The separation tank here has a connection to the valve, a connection to the actuator device, and also a multiplicity of openings which firstly prevent the liquid droplets from emerging from the tank and secondly permit droplet evaporation because of waste heat acting on the tank. The invention furthermore relates to a valve unit with such a liquid collection and evaporation device, and to a vehicle with such a valve unit.

A valve stem includes a valve stem body connected to a valve stem head. The valve stem is for use with a choke valve. The valve stem body has first and second ends with an expandable valve stem tip extending from the second end of the valve stem body, The valve stem tip expands radially outwardly in an opening in the valve stem head to secure the valve stem head to the valve stem body.

A seal assembly for a valve stem comprises an external seal placed on a valve stem facing an external environment; an internal seal placed on the valve stem facing a process environment; the external and internal seals define a chamber for the containment of barrier fluid; the chamber has an inlet configured to be placed into fluid communication with a source of barrier fluid; a detector of the amount of barrier fluid; a pressurizer device for providing the chamber with a positive pressure with respect to the process environment; the pressurizer device is configured to be installed coaxially with the valve stem.

A number of variations may include a product comprising: a bushing (100) located at a cavity (56) formed by a stationary body (46) of a valve (12), and located around a movable stem (48) of the valve (12), wherein the bushing (100) facilitates movement of the stem (48); and a seal member (102, 104) located in the cavity (46), around the stem (48), and on the inboard side of the bushing (100), wherein the seal member (102, 104) substantially prevents fluid-flow between an outer diametrical surface (76) of the stem (48) and a confronting inner diametrical surface (120, 128) of the seal member (102, 104), forming a first seal.
