ELECTRIC VACUUM BUTTERFLY VALVE
Precision-Engineered for Automated High-Vacuum Control in Semiconductor, Aerospace & Industrial R&D

Product Overview

The Electric Vacuum Butterfly Valve combines motorized actuation with ultra-low leakage performance (≤1.3×10^-5 Pa·L/S) to deliver reliable flow control in high-vacuum systems. Engineered for -29°C to 150°C operation and compatibility with KF/ISO flanges, this valve is ideal for automated processes in semiconductor fabrication, vacuum coating, and space simulation chambers. Constructed entirely from 316L stainless steel, it resists corrosion in harsh environments while maintaining vacuum integrity.
