Maintenance guide for air-operated valves, pneumatic actuators, and accessories
- Fossil Technologies, Inc., Kelso, WA (United States)
Air Operated Valves (AOVs) are used extensively in the power generation industry for process control and system isolation functions. Their proper operation is essential to reliable power plant operation. This guide discusses major components such as actuators, valves, and positioners, and explains the inter-relationship of these components. Diagrams indicating the application and operation of various types of actuators are presented as an aid for thorough investigation of malfunctioning equipment. Recent developments on diagnostic equipment for AOVs are covered and valve traces on valves with maintenance related problems are used to demonstrate how the diagnostic equipment can quickly solve complex valve problems. In addition, predictive and preventive maintenance recommendations based on specific failure data are included. The guide also includes a troubleshooting section with tables providing easily accessible information to minimize troubleshooting costs. Appendices augment the guide by providing a glossary of terms and various engineering schedules including useful engineering parameters for the proper maintenance of air operated valves and accessories.
