The Comparison Between Diaphragm Valve and Corrugated Pipe Valve in the Zrbrewing Sterilizing

Abst:

In the sterile industry, the competition between corrugated pipe valve and diaphragm has been lasted for a long time. The diaphragm valve takes up the advantage because it is simple in structure, cheap in price and convenient in zrbrewing sterilizing . Compared with this valve, the corrugated pipe valve has too few specifications in the market. While, since Tuchenhagen Company produces the Vesta corrugated pipe valve, it fills the gap. Now the article will introduce the merits and demerits clearly through the comparison between the two valves.

Firstly, the property for emptying. When the diaphragm valve is used in the horizontal pipe, people must ensure the installation should be followed the instruction of the manufacturer. Or else, in the operation process, the capacity for emptying will have some problems and can not completely discharge the medium in the valve. But, different types of these valves have different angles of inclination for installation, which cause a lot of problems to the designs of the sterile process equipment. Especially for the T structure diaphragm valve, the problem of emptying property is more obvious. Compared with the above valve, the corrugated pipe valve will never have such a problem. No matter which structures the valve body is, the corrugated pipe valve will never emerge the dead angle when it operates. Thus, it ensures to cut off the pipe strictly. And it can be installed in the pipe system with sterile equipment according to different mounting means.

Secondly, the comparison of device availability. As the user of the equipment, he should try his best to make use of the equipment as much as possible. The corrugated pipe valve will be worn in general situation. For the diaphragm valve, once it is worn, it must be changed. As far as know, its operation time depends on the relevant production process. On one side, many factors such as the corrosion of the flowing medium, the clearing for the pipe, the temperature for zrbrewing sterilizing , working pressure will influence the service time. On the other side, the deformation of the septum also can decide the valve's time for usage.

Thirdly, durability. Most diaphragm valves do not be destroyed during operation. Instead, they are destroyed by the mechanical compression. Although the diaphragm valve has different flexible classes, different coatings and PTFE frame covers, all of the valves still will be worn by the inside medium. Therefore, it is necessary to often change the valve in the sterile process. But the corrugated pipe valve need not be often changed and it can be used for many production processes.
