High Vacuum Flap Valve for Large Scale Coating and Photovoltaic Systems

This high-performance high vacuum flapper valve is a specialized vacuum isolation and flow control device designed for ultra-high vacuum, large-flow, and photovoltaic or large-scale coating system conditions. Utilizing a flapper-style flip opening and closing structure, it is suitable for the entire range from ultra-high vacuum to atmospheric pressure (5×10⁻⁸ Pa to 1×10⁵ Pa). It enables rapid connection, disconnection, and sealed isolation for large vacuum chambers and production lines. With advantages such as stable dynamic balance, low particle generation, compact structure, and high customizability, it is the core preferred equipment for vacuum system isolation and control.
