    摘要: A valve assembly includes a valve body defining a fluid inlet in fluid communication with a fluid outlet. The valve body has an inner body surface defining an interior chamber extending between the fluid inlet and the fluid outlet. A valve element is disposed within the interior chamber and rotatable through a range of positions relative to the outlet providing a high level of precision control of a fluid flow rate through the valve assembly. A valve seat with a seal is positioned around a valve element. The valve seat is configured to self-adjust its inner radial diameter to correspond to the outer radial diameter of the valve element to maintain a portion of an inner seat surface in contact with an outer valve surface of the valve element through the range of positions.

    摘要: A butterfly valve includes a body (102) defining a passageway (112) between an inlet (114) and an outlet (116). The butterfly valve includes a first flexible seal (106) coupled to a first surface of the body (102) adjacent the inlet (114) to engage a first portion of a disk (104). The example butterfly valve also includes a second flexible seal (108) coupled to a second surface of the body (102) adjacent to the outlet (116) to engage a second portion of the disk (104) different than the first portion.

    摘要: The invention relates to a flap valve comprising a seal (34) that has an annular seal body made of an elastomeric material and comprising an annular groove (26) for receiving the seal (34). The seal body has a radially inner wall section (36) relative to a longitudinal axis (16) of the seal body, said inner wall section having a seal surface (46), and a radially outer wall section (38) that has a greater longitudinal extension in the direction of the longitudinal axis (16) than the radially inner wall section (36), said radially outer wall section (38) forming a step (40) with the radially inner wall section (36). The radially outer wall section (38) is received in a radially outer groove section (28) of the groove (26) in a formfitting manner such that the longitudinal ends (42, 44) of the radially outer wall section (38) are held in the radially outer groove section (28). The radially outer wall section (38) has a reinforcement (50) made of a material that is more rigid than the elastomeric material, said reinforcement (50) axially supporting the radially outer wall section (38).
