A solenoid actuator includes a housing assembly, a bobbin assembly, a coil, an armature, an actuation rod, a guide ring, a lower spring guide, an upper spring guide, and a spring. The actuation rod is fixedly coupled to the armature, and the guide ring, the lower spring guide, the upper spring guide, and the anti-rotation structure all comprise a non-metallic material.

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.

A diaphragm is provided that includes a plurality of zonal portions that define reinforced and non-reinforced areas of the diaphragm. A first zonal portion extends from a marginal edge portion toward a central portion and is formed of a fabric material. A second zonal portion extends from the first zonal portion toward the central portion and is formed of an elastomer. A third zonal portion defines the central portion and is formed of a fabric material. The combination of reinforced and non-reinforced portions provides for a decrease in the radial tension (spring rate) of the diaphragm and helps prevent undesired changes to the flow control valve flow setpoint.
