German VAI valve VAI model VAI price
With a constant pressure differential across the VAI valve, the flow rate of a standard valve changes little when the opening varies over a wide range. However, at a certain opening, the flow rate changes sharply, indicating poor regulation performance. A control valve adjusts the valve core stroke according to the direction and magnitude of the signal to change the valve's resistance coefficient, thereby achieving flow regulation. Control valves are classified into manual and automatic types. Both manual and automatic control valves come in various types with different regulation performances. Automatic control valves include self-acting flow control valves and self-acting differential pressure control valves. VAI valve connection
German VAI bearings, VAI models, VAI prices
VAI bearings are precision mechanical components that convert sliding friction between the rotating shaft and the bearing housing into rolling friction, thereby reducing frictional losses. Rolling bearings generally consist of four parts: inner ring, outer ring, rolling elements, and cage. The inner ring fits with the shaft and rotates with it; the outer ring fits with the bearing housing to provide support; the rolling elements are evenly distributed between the inner and outer rings by the cage, and their shape, size, and quantity directly affect the performance and service life of the rolling bearing; the cage ensures uniform distribution of the rolling elements and guides
VAI filter Germany VAI model VAI price
The prototype of the VAI filter is a respiratory protective device used by people to protect their breathing. The rapid development of air filters is closely related to the development of the military and electronics industries. According to records, as early as the first century in Rome, people used masks made of coarse linen for protection when purifying mercury. In the long period that followed, air filters also made progress, but they were mainly used as respiratory protective devices in some hazardous industries, such as the production of harmful chemicals. To clean contaminated air to the state required for production and daily life, that is, to make the air
