How to ensure that the control valve reliable operation and quality

To ensure the reliable operation of the control valve, here not only refers to the manufacturing quality of the control valve itself, but also involves the correct calculation of the control valve, valve selection, as well as including the operator training and quality improvement. In order to prevent misuse, the process personnel must pay attention to the nameplate of the notice, according to our new new pneumatic control valve (GB / T4213-92), the actuator nameplate at least marked with the manufacturer's name, product type, the rated flow coefficient , Design number, product number and year of manufacture, etc .; the body will have to cast or punch out the arrow indicating the flow of media and the "DN" value and the "PN" words and values ​​can also be marked with the valve Body firmly fixed on the nameplate. Important control valve should be equipped with enough accessories, such as valve positioner, limit switches. Have enough space for installation and operation, adequate lighting, strict operating procedures. In order to ensure the quality of regulating valve, the selection of regulating valve to go through the correct calculation; type, caliber, the performance must meet the requirements; control valve of all important parts of the material to be strictly selected; to have sufficient strength and stiffness; To pass the pressure test in accordance with national standards, air tightness and other tests; manufacturers of manufacturing technology and test methods must meet the standards, to be recognized by the competent authorities recognized.
