Within the boiler, piping and pressure vessel industry, control and safety relief are of Most essential importance. Pressure relief valves are the last line of defense against Catastrophic failure or even loss of life. The course covers control and safety valve types And designs, materials, specification and selection, preventive maintenance procedures, Operation and troubleshooting. The course provides a basic and specialized knowledge of valve types and designs, Materials used to make valves, where various designs should and should not be used, Factors to consider in specifying a valve for a specific application, how to calculate flow Through valves, and valve maintenance and repair. In addition to presenting information.
By the end of this course delegates will be able to:
- Familiarize participants with the functions and applications of control and safety
- Relief valves, their types, designs and components.
- Introduce the participants to normal valve operation, bypass operations, abnormal
- Conditions, inspection and preoperational checks.
- Enable appropriate control and safety valve sizing and selection for liquid, gas and vapour applications.
- Train participants to install, disassemble, clean, inspect, align, and reassemble a Variety of control and safety valves.
