Abstract
A fluid regulator includes an actuator assembly disposed in a valve body. A sleeve includes a cylindrical wall, a first plate, and a second plate. Each of the first plate and the second plate is disposed in a cavity of the sleeve. A stem extends through the sleeve and is axially aligned with a longitudinal axis of the body, and includes a passage extending partially through the stem. The actuator assembly includes first and second pistons. First, second, third, and fourth chambers are separately disposed between the sleeve, the first or second plate, or the first or second piston. The first and third chambers are in fluid communication, and the second and fourth chambers are in fluid communication via the passage of the stem. The actuator assembly actuates a control element in response to a fluid pressure receivable in the first, second, third, and/or fourth chambers.
