Valves are tested to ensure that they are functioning properly and providing accurate control of the process. Valves affecting hospitals, schools, and valves on water mains of diameter 16-inches or greater should be given priority, and should be exercised/assessed once per year. `4 TPI will provide a detailed report of the inspection results, including any issues identified during the inspection. Documentation: The results of the valve inspection, testing, and calibration should be documented and kept on file for future reference. Close the valve and apply pressure to the system. It also has a 4-20mA valve position feedback output. %PDF-1.6 % Control Valve Stroke Test Procedure - InstrumentationTools Step 1: Initial check the position of the valve open/ close then stroke , check the air pressure 4 kg/cm. The pneumatic shell test pressure shall be 110 % of the maximum allowable pressure at 38 degrees C (100 degrees F) or as specified in the purchase order. Preparation: Gather all necessary tools and equipment, such as a multimeter, torque wrench, pressure gauge, and valve position indicator. Select 4mA in the calibrator (also called as source meter). Control Valve Assembly: Includes all components normally mounted on the valve: the valve body assembly, actuator, positioner, air sets, transducers, limit switches, etc. A bellows seal globe valve is an essential component in many industries, such as chemical, oil and gas, and petrochemical industries. Mr. Jadhav Amits article on the Control valve stroke test is very informative.
