A thermal management module comprises a housing and a drive shaft located within the housing. The housing is provided with a first internal cavity, a partition and a second internal cavity which are arranged in series along the axial direction of the drive shaft. The first internal cavity and the second internal cavity are separated by the partition. The partition is proved with a through-hole through which the drive shaft passes. One end of the drive shaft extends into the first internal cavity. A second internal cavity is used for receiving a drivetrain for rotating the drive shaft.

A rotary seal comprises a seal element comprising a disc-shaped body having a first axial side and an opposed second axial side. The seal element further comprises a radially inner central circular opening for receiving a rotary shaft, the opening having an inner periphery for sealing engagement with the shaft. A radially outer rim portion of the seal element comprises an axially facing annular sealing surface provided on the first axial side for sealing engagement in use with an opposed axially facing sealing surface of an adjacent first static housing and an axially facing pocket provided on the second axial side and having an axially facing surface for receiving, in use, an annular elastomeric biasing element. At least one drainage passage is formed through the outer rim portion from an inlet on the second axial side to an outlet on a radially outer portion of the rim portion.

A valve upper part, in particular for sanitary fittings, includes a sleeve-type head piece, which can be fastened in a valve housing of a fitting and through the center of which a spindle extends, which has a handle connection and is mounted for rotation about the longitudinal axis of the spindle and by which a valve body can be actuated, a groove being formed in the spindle, which groove receives an elastic sliding bush, which radially surrounds at least some regions of the spindle and which lies against at least some regions of the inner lateral surface of the head piece.

A stuffing box assembly for a valve includes a stuffing box and a packing module. The packing module carries one or more seals to engage with the stuffing box and a valve stem extending through the stuffing box. The packing module is able to be installed into, and removed from, the stuffing box as a single assembly. A valve stem can be formed with an integral ball on one end for engaging with a valve seat. The seals of the packing module create a fluid-tight seal against the valve stem and the stuffing box to inhibit fluid leakage through the stuffing box.

A connection socket for a tubular connection that includes: a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess; a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature, and a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition. Further, the secondary seal has a melting temperature at or above the service temperature of the primary seal.

Valve stem packing assemblies may include at least one end ring and at least one sealing ring. The at least one end ring may include an inner ring and an outer ring. Valves include a valve body, a valve stem, and a valve stem packing assembly.

Valve stem packing assemblies may include at least one end ring and at least one sealing ring. The at least one end ring may include an inner ring and an outer ring. Valves include a valve body, a valve stem, and a valve stem packing assembly.

A flow control device for a heat exchange system. The device includes a housing, a valve core and a transmission element. The housing is formed with an accommodating portion, a first port and a second port, the valve core being at least partially accommodated in the accommodating portion. The housing includes fixing elements and an outer housing, the fixing elements being located on a circumferential inner side of the outer housing, the outer housing and the fixing elements are arranged in a relatively sealing manner, and the valve core and the fixing elements are arranged in a relatively sealing manner. The valve core at least has a first flowing passage. The transmission element drives the valve core to open or close at least one of the first and second ports, thereby improving an internal sealing performance of the product.
