This Practice describes requirements for selection and sizing of pneumatically actuated control valves, including requirements for body, bonnet, trim, actuator, accessories, and noise considerations. This Practice does not cover requirements for motor-operated valves, on-off valves, on-off valves intended for emergency isolation, or valves with hydraulic actuators. For these types of on-off valve applications see PIP PCECV003, Guidelines for Application of Remotely Actuated On-Off Valves.
