Large Aperture Electric Rectangular Vacuum Gate Valve for Space Simulation and Coating Systems

This high-performance Large Diameter Electric Rectangular Valve is a heavy-duty vacuum isolation and transmission equipment specifically designed for ultra-high vacuum, extra-large openings, and space simulation or large-scale coating system conditions. Featuring a large-sized rectangular straight-through structure, it is suitable for the full range from ultra-high vacuum to atmospheric pressure (5×10⁻⁸ Pa to 1×10⁵ Pa). It enables rapid isolation and sealed cutoff for large process chambers and vacuum systems. With advantages such as consistent valve plate sealing pressure, integrated control, stable dynamic balance, and high customizability, it is the standard core valve for large-scale vacuum system isolation.
