Course Overview

Power Plant, petrochemical, and other oil and gas companies do deal with different types of valves. All piping systems are fitted with valves for controlling reasons or safety necessities. Understanding the purpose of each valve type will have a significant reflection on the process quality, equipment and plant reliability, and the economics of the whole action.

The different application requires to select the appropriate valve type of specific flow characteristics. The operation and Function of the valve also affect the system and the process. Understanding the difficulties and problems associated with valves is vital for diagnosis and troubleshooting and the necessary maintenance for the particular type of valves.

Valves can be categorised as manual or control valves. What type of valve is a control valve? When a manual valve is operated via an actuator, it becomes a control valve. Valves in common do control the rate of flow in a piping system, the direction of the flow, or perform as a relieving device to protect the system from over pressurization.

Valves like check valves would avert the flow from reversing, thus protecting equipment from reverse flow. Such valves function automatically without the need for any type of actuation. Stop and close valves are used predominantly to isolate a system in a situation of maintenance and/or putting the standby equipment in services. The function and purpose of a valve are what determines its design.

The right choice of a valve in terms of its type and size, and its pressure class is what affects most the stability and reliability of the system. The nature of the fluid, the type of the process, the level of temperature and pressures are parameters and considerations affecting the valve selection.

The flow through a valve will experience distinctive effects, like cavitation, flashing, and noise. Water hammer is one of the special effects that a check valve may cause. Such occurrence might lead to different kind of problems, some would affect directly the valve itself and other might distraught the process as a whole or result in system erosion or corrosion.

Vibration and instrumentation false function might also be an effect of a faulty valve. Some of these complications can be avoided in the stage of selection and sizing of the valve. Others could be removed in the process of writing the specifications and through good communications with the manufacturer or vendor.

Thoughtful considerations of these different types of problems will help in troubleshooting the valves and the systems and help to cure the problems. Wrong installations could be the cause behind many of the valves problem too. At the base of any process are the field devices that measure and control the flow of air, steam, water, gas or hundreds of other materials.

Without suitable basic setup, calibration and configuration of these devices, advanced control techniques cannot deliver the levels of efficiency the technology is capable of. Information of process control devices within a plant is regularly passed down from generation to generation.

At the same time, if advances in process technology and methodology typically brought about by training aren’t brought into the plant, in-house benchmarks for device setup and maintenance can become based on outdated theory. The outcome is that while a valve or instrument may be working, it may not be functioning up to its capabilities and is not delivering on its assured performance.

This Zoe training course analyses design and operating principles of control valves, actuators, positioners and related accessories. It explains the sizing and selection methods for a wide-ranging variety of control valve assemblies.
