When choosing a control valve, we typically consider some of the traditional factors such as pressure rating, pressure drop, flow media, temperature, and cost. However, with the changes of the times and the continuous improvement of science and technology, valve design is also advancing with the times, and the cost-benefit characteristics of the production process are greatly enhanced compared with the past. This has greatly weakened the importance of traditional factors that have to be considered before, and the evaluation of dynamic characteristics has become a key factor in the selection of valves. Here, we always stress that "dynamic characteristics" is the key to choosing a valve: If we only measure the valve, it is hard to know what kind of performance the valve will show under actual operating conditions. Traditionally, it has been our belief that careful adjustment of the static factors will optimize the performance of the valve, but the fact makes us realize that this is not always the case. Through thousands of performance tests by researchers and manufacturers, we can see that many domestic valves, which have been chosen by considering traditional factors, do not produce much expected results in optimizing control loop performance. A professional research has shown that the dynamic characteristics of the valve to reduce process variability has a very important role. More data show that in many processes, different valves to reduce process variability, even if the difference is small, can greatly improve the production efficiency and reduce waste, and achieved great economic benefits. The traditional view is that the improvement of process optimization always comes from the control room control instrument upgrade. However, based on the resulting professional test data, the valve dynamics will have a significant impact on circuit performance if we use the same control instrumentation.
Label Remover
Label Remover is necessary part of PET Bottle Recycling Machine. It can remove the label automatically. This label separator can remove label without water, it can save a lot of water, reduce the water consumption.PET bottle label removing machine complete change the previous way of removing the label by manual work. Because it is greatly improving the productivity and reducing the labor intensity. Also with crusher and strong air blower, the cap and label could be separately sorted out according to our customer's desire.
Mechanical friction removing, blower sucking out,smaller motor comparing with conventional label removing machine, low electric consumption,lower running cost,optimized inside structure design, label removing degree upto 100%.
The labels will be peeled off by self-friction.The bottles are fed into the top of the machine, and discharged from the bottom.Using this machine can have high-purity recycled flakes.The capacity for this series machine is 300-2000kg/h.
