Control Valve Calibration Step-by-Step | Full Guide for Pneumatic Valve & Positioner

​Welcome to this hands-on tutorial on Pneumatic Control Valve Calibration! 🛠️ This video provides a comprehensive, step-by-step guide for technicians and engineers on how to accurately calibrate a control valve and its positioner (or I/P converter). ​Mastering control valve calibration is essential for maintaining accuracy and stability in any PID control loop. We cover the setup, the tools, and the critical adjustments required. ​In this detailed procedure, you will learn: ​The Required Equipment and proper setup (Process Calibrator, Multimeter, Air Supply). ​The importance of Process Isolation for safety and accurate calibration . ​How to perform Zero and Span adjustment by applying 4mA and 20mA signals. ​The complete check for the valve stroke and position indicator. ​📺 Video Chapters (Jump to the step you need): ​0:00 - Introduction & Why Control Valve Calibration is Critical ​0:45 - Required Equipment and Setup ​1:30 - Step 1: Process Isolation and Safety Check ​2:15 - Step 2: Regulating Instrument Air Supply ​3:00 - Step 3: Connecting the Process Calibrator (Source Current Mode) ​4:10 - Step 4: Zero Adjustment (4mA) - Verify 0% Stroke ​5:20 - Step 5: Span Adjustment (20mA) - Verify 100% Stroke ​6:30 - Quick Check and Final Connection ​👉 Click to subscribe for more essential Industrial Instrumentation and Maintenance training!
