When it is necessary to use bellows stop valve in horizontal pipeline, electric stop valve is a relatively new type of stop valve. It has some unique advantages of its own structure, such as no friction of switch, difficult wear of seal and small opening and closing torque. This reduces the size of the actuator.

Equipped with multi rotation electric actuator, the medium can be adjusted and cut off tightly. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions requiring strict cut-off. It must be ensured that the bellows stop valve is installed in the horizontal pipeline according to the angle specified by the bellows stop valve manufacturer. Otherwise, during the operation of process equipment, the emptying of diaphragm valve will encounter some problems and the medium in the valve body cannot be completely discharged.

However, the installation inclination angles of different diaphragm valve types, bellows stop valves produced by different manufacturers and diaphragm valves with different nominal flow are different, which often brings great trouble to the design and manufacture of sterile process equipment. In the T-shaped bellows stop valve, the problem of emptying the valve body is more obvious.

Compared with the bellows stop valve, Vesta bellows valve will not have such a problem. No matter what structural form the valve body of Vesta bellows stop valve is, there will be no "dead angle" during the no-load operation of the process equipment, so as to ensure the strict isolation of the pipeline. Moreover, it can be installed in the pipeline system of sterile process equipment according to different installation methods.

In the pharmaceutical manufacturing industry, aseptic process equipment consists of many horizontal and vertical pipelines. In the design of pharmaceutical equipment, due to pipeline position and technical reasons, this bellows stop valve must be installed and used at a specific position. For example, if a bellows stop valve is installed in a vertical pipe, it must be connected through a 90 ° elbow in the same horizontal plane. The production cost of T-type diaphragm valve is very high. Compared with diaphragm valves with different body structure shapes, bellows valve has more advantages in volume and shape, connection and installation with pipeline. Due to the different structural types of the two types of stop valves, in the early stage of aseptic process equipment design, it is necessary to select which type of stop valve should be selected for each part.

In the fields of medicine, food and biotechnology, there are a large number of valves that need to be disinfected. Large valves are almost useless in such occasions where disinfection is needed. Because, in these process equipment, the medium quality required to be transported is less and less. For less flow, people almost choose diaphragm valve without exception. The new bellows valve has a smaller volume and can be used with different pipe diameters. It has more advantages than diaphragm valve in this regard.
