high vacuum ball valve Description
High vacuum ball valve is a valve specially designed for use in vacuum systems. Its main features and applications are as follows:
Main features
Low pressure operation: The working pressure of high vacuum ball valve is lower than the standard atmospheric pressure, which is suitable for use in vacuum environment.
Excellent sealing performance: The reliable lip elastic valve seat design can effectively prevent leakage, and the valve leakage rate can usually be controlled at a low level, such as ≤1.3×10^-14 Pa·m³/s.
Simple and compact structure: The overall structure is simple and the installation size is small, which not only saves space, but also the installation process is relatively simple, which can reduce the installation cost and difficulty.
Convenient operation: The driving torque is small and the operation is simple. It only needs to rotate 90 degrees to achieve fast opening and closing. The switch operation can be completed in a short time, which improves work efficiency.
Use with positive and negative pressure: It can be used in high vacuum state and low pressure system, with a wide range of applications, which can meet the needs of different working conditions.
Diverse material selection: Different materials can be easily selected for different purposes and working conditions. For example, the valve body, valve cover, and valve stem are usually made of stainless steel, and the seals can be made of tetrafluoroethylene, nitrile rubber, fluororubber, PPL, etc. to adapt to various corrosive, high temperature or low temperature and other special environments.
Easy maintenance: Standardized and modular design, easy to replace and repair, easy to clean, the manual ultra-high vacuum ball valve also adopts energy-saving design and small size, which further reduces the maintenance cost and difficulty.
