摘要： An apparatus is provided for a valve actuator assembly comprising an actuator housing, a piston, and a spring. The piston is disposed within the actuator housing. The piston is configured to couple to a valve element, and includes an inner cylindrical section and an outer cylindrical section. The outer cylindrical section of the piston is spaced apart from the inner cylindrical section to define a recess. The piston is further configured to move within the actuator housing in a first direction and a second direction, to thereby move the valve element toward a first position and a second position, respectively. The spring is disposed within the actuator housing, and is configured to supply a bias force that urges the piston to move in the first direction. The spring is at least partially disposed within the recess, and at least partially surrounding the inner cylindrical section.

摘要： Seals, ball valve assemblies, and methods of operating ball valves assemblies are provided. The seal includes an annular jacket, a restrictor, and a spring energizer. The annular jacket includes a first annular pocket and a second annular pocket. The restrictor is disposed in the first annular pocket and is capable of restricting shrinkage of the first annular pocket to a predetermined diameter range, if the seal is exposed to a temperature within a predetermined temperature range. The spring energizer is disposed in the second annular pocket and is configured to supply a force against the annular jacket to maintain the seal against a contact surface.

摘要： A straight shaft sealing valve assembly includes a valve body, a shaft, a valve element, and a seal element. The valve body has an inner surface that defines a flow channel. The shaft is rotationally mounted on the valve body and extends across the flow channel. The shaft includes a first seal opening and a second seal opening. The first and second seal openings are spaced apart from each other and extend through the shaft. The valve element is coupled to the shaft and is rotatable therewith, and has an outer periphery. The seal element is coupled to the valve element, extends from the outer periphery, and extends through the first and second seal openings.
