Vacuum tightness - the ultimate pursuit

In the field of ultra-high vacuum, gas molecules are extremely thin, and even a very small leak is like throwing boulders into a quiet lake, instantly breaking the "tranquility" of the vacuum. In order to achieve the almost harsh sealing requirements, the selection of sealing materials can be described as unique. Fluoroprene stands out for its excellent weather resistance, low permeability and high elasticity. When the valve plate is closed, the fluoroprene gasket is like a tight guardian, tightly fitting between the valve body and the valve plate, completely sealing the gap at the microscopic level, so that the gas molecules can be drilled seamlessly.

At the structural design level, the contact surface of the valve seat and the valve plate has been ultra-precision grinding, and the flatness has reached the micron level, which is like two tightly stitched puzzles and fastened with high-precision bolts to ensure the uniform force of the entire sealing interface and further reduce the leakage rate. Compared with ordinary valves, its leakage rate can be reduced by several orders of magnitude, ordinary valves in high vacuum environment may have hundreds of gas molecules per second leakage, and ultra-high vacuum plug valve can control this number in the single digits or even lower, such as particle accelerators in high-energy physics experiments, precision optical path systems in quantum optics research, etc., to provide a stable and pure vacuum environment. So that the exploration of the micro world can be accurately advanced.

Conductivity - Efficient airflow channels

When scientific research and industrial production require large flow of gas or particles to quickly pass through the valve, the conduction advantages of the ultra-high vacuum plug valve are obvious. The interior channel is designed to be spacious and smooth, like a wide and unobstructed highway, reducing the collision and blockage of gas molecules. When the valve plate is opened, the nearly full-aperture conduction state allows the air flow to pass rapidly, greatly shortening the time for pumping or inflating.

In the chemical vapor deposition process of semiconductor manufacturing process, a large number of reaction gases need to enter the reaction chamber quickly and evenly, and the ultra-high vacuum plug valve ensures the rapid transport of gas with excellent conductivity, so that the surface of the silicon wafer can be deposited efficiently and uniformly, improving the yield and efficiency of chip manufacturing.

In aerospace simulation experiments, when simulating the high-altitude rarefied gas environment, the rapid switching of evacuation and inflation also depends on its efficient conduction performance, so that the experiment can accurately reproduce the complex and changeable space environmental conditions, and provide strong support for the design and testing of spacecraft.

Stability and durability - a lasting guarantee

In the face of high temperature, high pressure, strong radiation and frequent opening and closing operation, the ultra-high vacuum plug valve shows extraordinary stability and durability with high-quality materials and exquisite structural design.

The valve body is made of high temperature and corrosion resistant stainless steel material, which can maintain the structural strength and dimensional accuracy even in several hundred degrees of high temperature baking environment (such as degassing process in vacuum electronic device manufacturing), and will not be deformed by thermal expansion and contraction to ensure the sealing performance is the same as before.

The connection structure between the valve plate and the transmission component has been specially strengthened, and the connector made of high-strength alloy steel, with precise tolerances, will not loosen and wear when subjected to repeated mechanical stresses. In the industrial coating production line, the valve needs to go through hundreds of opening and closing cycles every day, and the ultra-high vacuum plug valve with its stable and reliable performance continues to ensure the efficient operation of the production line, reduce the production maintenance caused by equipment failure, save a lot of costs for enterprises, and become an indispensable solid backing in the modern high-end manufacturing field.
