• ISA75.24, Control Valve Actuator Sizing and Selection


    Standards Button

    Scope

    Identify the forces that act on closure components and actuators. Describe how these forces work in the positioning of closure components. Prepare equations required to determine an actuator (i.e. pneumatic, hydraulic, or electric) size based on piston or effective diaphragm area and spring characteristics.

    This subcommittee will address control valves that directly transmit actuator linear motion to the closure components. This would normally include such styles as globe and cage valves.

    Purpose

    This subcommittee has been formed to determine the forces and system parameters that influence control valve actuator sizing requirements, and to develop standards or technical reports and to interpret and promote the technology involved for the sizing and selection of control valve actuators. Forces related to the valve, actuator, and process will be identified. Equations will be developed for the solution of these forces, and the resulting actuator sizing selection criteria will be established.
