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 wholesomeness considering it is mere in structure, unseemly in price and user-friendly in sterilization. Compared with this valve, the corrugated pipe valve has too few specifications in the market. While, since Tuchenhagen visitor produces the Vesta corrugated pipe valve, it fills the gap. Now the vendible will introduce the merits and demerits unmistakably 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 topics for emptying will have some problems and can not completely venting the medium in the valve. But, variegated types of these valves have variegated wiles of inclination for installation, which rationalization a lot of problems to the designs of the sterile process equipment. expressly for the T structure diaphragm valve, the problem of emptying property is increasingly obvious. Compared with the whilom valve, the corrugated pipe valve will never have such a problem. No matter which structures the valve soul is, the corrugated pipe valve will never sally the sufferer wile when it operates. Thus, it ensures to cut off the pipe strictly. And it can be installed in the pipe system with sterile equipment equal to variegated mounting means.

Secondly, the comparison of device availability. As the user of the equipment, he should try his weightier to make use of the equipment as much as possible. The corrugated pipe valve will be worn in unstipulated situation. For the diaphragm valve, once it is worn, it must be transpirationd. 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 transplanting for the pipe, the temperature for sterilization, working pressure will influence the service time. On the other side, the deformation of the septum moreover can decide the valve'
