How to choose process control valve control valve requirements usually area according to the craft, the application and the end user specifications. Process conditions and parameters also have very big difference, including pressure, temperature, controllability, cavitation risk, environmental impacts, noise, etc. In addition, priority may be different. The end user may want to know more about valve performance and controllability and total life cycle cost information, and the EPC contractor may be more concerned about the CAPEX related cost and delivery time. How do you know where to start - And where to seek to rely on high quality information to help? Ideal method is called valve experts to assist your local engineering team, some size calculation, specified requirements and identify abnormal situation, in order to achieve the ideal performance and controllability. Simply repeat before in similar projects are doing is not a good choice. Subtle changes in the process of serious impact on the valves and other equipment. In addition, up to date is very important - efficiency of local regulations and requirements And select the valves can meet these requirements. The world there is no best valve valve to handle all applications. Each type of valve plays a certain role. So I know which one to choose the task at hand is very important. Globe valve is the ideal choice of the general application and high pressure difference. One reason is because their intrinsic resistance to cavitation. 。 Replacement of valve adjustment is easy, if process conditions change quickly or plant capacity increasing, it is particularly useful. These valves is the ideal choice of the cleaning medium flow noise reduction, also widely used in micro flow service. Block valve is a kind of economic solution, can be achieved through a smaller nominal valve size high capacity. This means that you can use smaller valve in the same application, and the valve can be installed in almost any direction. Block valve is also a great option for fibre and impurity liquid medium. Eccentric rotating plug valve is a kind of compact and reliable solutions, suitable for general and more demanding applications. These valves are widely used in oil refinery and chemical plants, because they can also be processing a dirty fluid particles. Butterfly Industrial Valves is light, economical solution, it is big size valves are particularly attractive solution. They usually have high flow and good discharge performance. Ball valve is solid structure, in particular control applications can be seen as a problem solver. However, they also is very heavy and expensive, so usually not control the use of first choice. However, for high pressure, the application of high capacity, from the point of view of technology and cost, they still are the best in the long term. When plants into more severe service running under high pressure and temperature, such as cavitation, flashing and noise control problem is becoming more and more common. If you don't take these problems seriously, they will soon lead to problems with valves and process itself. It is important not to normal operating point selection valve based on a single, but taking into account all possible process conditions. Size and selection should be based on the minimum, normal and maximum process conditions and flow value. Gain the best results from the valve in full set, we believe it is important to every detail. Therefore, we offer a comprehensive product portfolio, linear and rotary valve is ready to provide experience for your valve selection, knowledge and the decades of delivery, installation and service of practical experience. We stand ready to in the entire life cycle of each valve to provide help for you, to provide support to maximize the extension of the normal operation of your process time, and make sure that you obtain the maximum performance.
