In the sterile area, competition between the corrugated pipe valve and the diaphragm was last long. The diaphragm valve is the advantage because it is simple in structure, cheap in price and practice of sterilization. Compared to the valve, the corrugated pipe valve also has some specifications on the market. Whereas since Univalve company produces corrugated pipe valve Vesta, it fills the void. Now, the article will present the advantages and disadvantages clearly through the comparison between the two valves.
First, the property drain. When the diaphragm valve is used in the horizontal pipe, people must ensure that the installation must be followed by the manufacturer’s instruction. Or, in the process of operation, the ability to drain will have problems and can not fully discharge the fluid through the valve. But different types of these valves have different inclinations to the facility, which cause many problems in terms of equipment sterile processing. Especially for the valve membrane structure T, the problem of emptying property is more evident. Compared to the valve above the valve corrugated pipe has never such a problem. Whatever the structure of the valve is the valve corrugated tube can never get out of the blind spot when it works. Thus, it ensures strictly cut the pipe. And it can be installed in the piping system with sterile equipment under different mounting means.
Secondly, comparing the availability of the apparatus. When the user of the equipment, he must do his best to make use of the material as possible. The corrugated pipe valve will be brought to the general situation. For the diaphragm valve, once it is worn, it must be changed. Regarding knowledge, the running time depends on the production process involved. On the one hand, many factors such as corrosion of the flowing fluid, compensation for driving, the temperature for sterilization, the working pressure will influence the time of service. On the other hand, the deformation of the wall can also choose the time of the valve for use.
Third, sustainability. Most diaphragm valves not be destroyed during the operation. Instead, they are destroyed by mechanical compression. Although the diaphragm valve has different classes, different coatings and PTFE flexible framework covers all valves will still be borne by the middle of the inside. Therefore, it is often necessary to change the valve in the sterile process. But the corrugated pipe valve does not need to be changed often and it can be used for many production processes.
