Key Topics Covered in the Handbook

The Fisher Control Valve Handbook is packed with information, but let's highlight some of the key topics you'll find inside. Understanding these areas will give you a solid foundation in control valve technology. Here’s a breakdown:

• Valve Types and Components: Learn about the different types of control valves (globe, ball, butterfly, etc.) and their specific applications. Understand the function of each component, such as the body, trim, actuator, and positioner. Knowing the various valve types and components is essential for selecting the right valve for a specific application. Each type has unique characteristics that make it suitable for different process conditions, such as pressure, temperature, and flow rate. The handbook provides detailed descriptions of each valve type, including their advantages and disadvantages, helping you make informed decisions. For example, globe valves are known for their precise control and tight shutoff, making them ideal for throttling applications. Ball valves, on the other hand, offer high flow capacity and quick opening/closing, making them suitable for on-off service. Butterfly valves are lightweight and compact, making them a cost-effective option for large-diameter pipelines. Understanding the function of each component is also crucial for maintenance and troubleshooting. The valve body provides the structural integrity, while the trim (including the seat, plug, and stem) controls the flow. The actuator provides the force needed to move the trim, and the positioner ensures accurate valve positioning. By understanding how each component works together, you can diagnose and repair valve problems more effectively.
• Valve Sizing and Selection: This section guides you through the process of properly sizing a control valve to meet specific flow requirements. It covers the use of flow coefficient (Cv) calculations and other factors that influence valve performance. Proper valve sizing is critical for ensuring optimal control and avoiding issues such as cavitation, flashing, and noise. The handbook provides detailed guidance on how to calculate the required Cv value based on process conditions, such as flow rate, pressure drop, and fluid properties. It also covers the use of valve sizing software and other tools that can simplify the process. In addition to sizing, the handbook also provides guidance on valve selection. This involves considering factors such as the type of fluid being controlled, the operating temperature and pressure, and the desired control characteristics. The handbook provides tables and charts that help you compare different valve types and materials, allowing you to make the best choice for your application. For example, if you're dealing with corrosive fluids, you may need to select a valve made of stainless steel or other corrosion-resistant materials. If you need precise control at low flow rates, you may need to choose a valve with a characterized trim. The handbook also covers the importance of considering the valve's turndown ratio, which is the ratio of the maximum flow rate to the minimum controllable flow rate. A valve with a high turndown ratio can provide accurate control over a wide range of flow conditions.
• Installation and Maintenance: Learn the best practices for installing control valves to ensure proper operation and longevity. Get tips on routine maintenance, troubleshooting common issues, and performing necessary repairs. Proper installation is essential for ensuring that control valves operate correctly and reliably. The handbook provides detailed instructions on how to install valves, including guidelines for piping, support, and alignment. It also covers the importance of proper sealing and torqueing to prevent leaks. Regular maintenance is crucial for extending the life of control valves and preventing unexpected failures. The handbook provides a maintenance schedule that outlines the tasks that should be performed on a regular basis, such as lubricating moving parts, inspecting for wear and corrosion, and testing valve performance. It also covers the procedures for disassembling and reassembling valves for cleaning and repair. Troubleshooting is an essential skill for anyone working with control valves. The handbook provides a comprehensive guide to diagnosing common valve problems, such as leaks, sticking, and noise. It also covers the use of diagnostic tools and techniques for identifying the root cause of the problem. The handbook also provides detailed instructions on how to perform necessary repairs, such as replacing worn parts, repairing leaks, and adjusting valve settings. It also covers the importance of using genuine replacement parts to ensure optimal performance and reliability.
• Actuators and Positioners: Understand the different types of actuators (pneumatic, electric, hydraulic) and how they control valve movement. Learn about positioners and their role in improving valve accuracy and response time. Actuators are the devices that provide the force needed to move the valve trim. The handbook covers the different types of actuators, including pneumatic, electric, and hydraulic actuators. Pneumatic actuators are the most common type, using compressed air to generate force. Electric actuators use an electric motor to drive the valve trim. Hydraulic actuators use hydraulic fluid to generate force, providing high thrust and precise control. The handbook provides detailed descriptions of each type of actuator, including their advantages and disadvantages, helping you choose the best option for your application. Positioners are devices that improve the accuracy and response time of control valves. They compare the actual valve position to the desired position and adjust the actuator signal to minimize the difference. The handbook covers the different types of positioners, including analog and digital positioners. Digital positioners offer advanced features such as diagnostics and communication capabilities, allowing you to monitor valve performance and troubleshoot problems remotely. The handbook also covers the importance of proper calibration and tuning of positioners to ensure optimal performance. It provides detailed instructions on how to calibrate positioners and adjust their settings to achieve the desired control characteristics. Understanding actuators and positioners is crucial for optimizing control valve performance and ensuring accurate and reliable control.
• Digital Valve Controllers: Dive into the world of digital valve controllers (DVCs) and their advanced features, such as diagnostics, calibration, and communication protocols. Digital valve controllers (DVCs) are advanced devices that provide enhanced control and diagnostic capabilities for control valves. They combine the functions of a positioner with digital communication and advanced diagnostic features. The handbook covers the different types of DVCs, including those that use HART, Foundation Fieldbus, and Profibus protocols. DVCs offer several advantages over traditional analog positioners. They provide more accurate and reliable control, allowing you to optimize process performance. They also offer advanced diagnostic features, such as valve signature analysis and online monitoring, which can help you detect and prevent valve problems before they cause downtime. DVCs also support digital communication protocols, allowing you to integrate them with plant-wide control systems and access valve data remotely. The handbook provides detailed instructions on how to install, configure, and calibrate DVCs. It also covers the use of DVC diagnostic features for troubleshooting valve problems. Understanding DVCs is essential for anyone working with modern control systems. They can help you improve process efficiency, reduce maintenance costs, and enhance plant safety.
