Product Characteristics And Core Classification Of VAT Vacuum Valves
2026-01-23
VAT Vacuum Valves are key components for zone isolation and airflow control in vacuum systems, specially designed for various vacuum working conditions covering high vacuum, ultra-high vacuum and extreme vacuum environments. With sophisticated design and stable performance, they have become core components of vacuum systems in fields such as precision manufacturing and scientific research experiments. As a professional vacuum valve brand originating from Switzerland, VAT has always focused on component reliability and working condition adaptability to build a product system that meets stringent process requirements. The core characteristics of VAT Vacuum Valves are reflected in multiple aspects. Valve bodies are mostly made of corrosion-resistant materials such as stainless steel and aluminum alloy, and some models are coated with special layers, which can resist erosion from corrosive and toxic process gases and adapt to different temperature working conditions. Certain products can withstand high temperatures above 400°C, meeting the needs of special scenarios such as vacuum furnaces and thin film deposition. Sealing performance is one of its core advantages: optimized through metal sealing or elastomeric sealing technology, the leak rate can be as low as 10⁻¹² mbar·L/s, whic...
Technical Advantages And Industry Application Scenarios Of VAT Vacuum Valves
2026-01-23
With differentiated technical design and full-scenario adaptability, VAT Vacuum Valves play a pivotal role in vacuum systems across various industries. Their technical advantages are reflected not only in basic performance, but also in customized solutions developed for pain points of different processes, while ensuring both system stability and long service life. In terms of technical design, VAT Vacuum Valves enhance comprehensive performance through a number of patented technologies. The motion curve control technology optimizes the valve's opening and closing rhythm, slowing down the speed near the closing point to reduce vibration and impact, avoid generating extra particles and protect sensitive process environments. The sealing structure is optimized in a targeted manner, and the sealing method is selected based on material characteristics and process requirements, which not only ensures air tightness when closed, but also reduces wear of sealing parts and extends the service life of components. The integration of an intelligent control module is one of the technical highlights: through the linkage of sensors and PLC control systems, it can monitor the valve's operating status in real time, support remote control and automated integration, and adapt to the operational needs of modern...
What Are The Application Scenarios Of DuPont Kalrez O-rings?
2026-01-23
DuPont Kalrez O-rings are suitable for harsh working conditions across various industries by virtue of their chemical corrosion resistance, wide temperature range adaptability and low contamination characteristics. They play a pivotal role especially in key processes requiring long-term stable sealing and avoidance of contamination and leakage risks. Their specific application scenarios are as follows: 1. Semiconductor Manufacturing As a core sealing component for semiconductor processes, Kalrez O-rings are adaptable to various plasma processes and vacuum environments, covering all key links in the entire chip manufacturing process. In deposition processes, for scenarios such as High-Density Plasma Chemical Vapor Deposition (HDPCVD), Plasma-Enhanced Chemical Vapor Deposition (PECVD) and Atomic Layer Deposition (ALD), they can withstand process gases including TMS, TEOS, NF₃ and O₂ as well as high-temperature environments (250℃ to 310℃). Certain grades such as Kalrez® 9600 feature low erosion and low weight loss, meeting the requirements of high-purity vacuum applications, reducing particle generation and outgassing, and ensuring wafer processing quality. In etching and ashing processes—whether conductor etching (150℃ to 225℃, in contact with media such as CF₄ and HBr), dielectric etching...
What Is The Chemical Corrosion Resistance Of Kalrez O-rings?
2026-01-23
Wide range of chemical resistance Kalrez O-rings can resist more than 1,800 types of chemicals, including strong acids (e.g., concentrated nitric acid), strong alkalis (e.g., sodium hydroxide), organic solvents (e.g., toluene, acetone, dichloromethane), ethers, ketones, esters, benzene ring solvents, strong oxidants, amine compounds, fuels, oils and greases, etc. Its perfluoro main chain structure has no active reaction sites, fundamentally eliminating the possibility of corrosion failure. Verification of chemical corrosion resistance Swelling test: After 6 months of immersion in a mixed solution of toluene, acetone and dichloromethane, Kalrez O-rings show almost no volume change, while other rubbers undergo severe deformation. Comparative test: When Kalrez and fluororubber are immersed in organic media such as acetone and toluene, fluororubber swells significantly after 16 minutes, whereas Kalrez remains stable. Advantages in chemical corrosion resistance Far superior corrosion resistance to ordinary rubbers: Kalrez can maintain its sealing performance even in extreme chemical environments, while ordinary rubbers may suffer from volume expansion and sealing failure due to molecular chain breakage or cross-linked structure damage. Better corrosion resistance than other perfluoroelastomers: K...
Slit Valve Door - Structural Principle And Core Characteristics
2026-01-23
The slit valve door is a special component for cavity isolation and on-off control in vacuum systems. Named for its adaptation to the rectangular "transfer slit" opening between the transfer cavity and the process cavity, it falls into the category of gate-driven isolation valves. With its compact structure and reliable sealing performance, it has become a key component of vacuum systems in high-end manufacturing and scientific research fields. Its core design is developed around the sealing and isolation requirements of vacuum environments, taking into account opening-closing response and cleanliness control, and is suitable for a variety of harsh working conditions. In terms of working principle, the slit valve door realizes the on-off of the flow path through the linear movement of the gate plate, forming an isolation barrier between cavities. In the closed state, the gate plate is closely attached to the valve seat, and the gas flow is blocked by structural pressure and the characteristics of sealing parts to maintain the vacuum state inside the cavity. In the open state, the gate plate rises and falls vertically to the top of the valve cavity, making the flow path fully unobstructed and providing a channel for the transfer of workpieces such as wafers and substrates or gas circulatio...
