A sealing assembly for use in a valve plate assembly includes a sealing ring and a retention spacer. The sealing ring has a radial ring section and an axial ring section, the axial ring section extends axially from the radial section and includes an outer diameter surface and a contact face, the contact face includes a contact surface and an annular slot, and the contact surface is located radially outward relative to the annular slot. The retention spacer is configured to be positioned adjacent the sealing ring.

A valve actuator includes an actuator housing, a piston, a linkage assembly, a magnet, and a Hall sensor. The actuator housing is adapted to receive pressurized fluid. The piston is movably mounted within actuator housing, and is configured to translate in a first direction and a second direction. The linkage assembly is rotationally coupled to the piston and is adapted to couple to a valve element. The linkage assembly is configured to rotate the valve element in a first rotational direction and a second rotational direction in response to piston movement in the first direction and the second direction, respectively. The magnet is mounted on the piston and is movable therewith, and the Hall sensor is mounted on the actuator housing and is responsive to movement of the magnet to supply a position signal.

Butterfly valve plate sealing assemblies are provided that include a sealing ring and a retention spacer disposed at least partially within a sealing ring groove formed about a periphery of a butterfly valve plate. The sealing ring includes a first portion, a second portion configured substantially perpendicular to the first portion, and a substantially L-shaped cross-section. The sealing ring is positioned at least partially within a groove opening and a groove body defining the sealing ring groove. The retention spacer is positioned at least partially within the groove opening and adjacent the first portion of the sealing ring. The retention spacer is configured to limit expansion of the sealing ring when under the influence of a pressurized fluid flow. The second portion of the sealing ring may be configured to optimize stiffness for a desired sealing ring tension.
