The control valve consists of two main components: the valve body assembly and the actuator assembly (or actuator system), which are divided into four series: single-seat series control valve, two-seat series control valve, and sleeve. Barrel series control valve and self-operated series control valve. Variants of the four types of valves can result in a number of different applicable structures, each having its particular application, features, advantages and disadvantages. Although some control valves have a wider range of applications than other valves, the control valves are not suitable for all operating conditions to jointly create the best solution for enhanced performance and reduced cost.
