Product Name: GI-A Series High Vacuum Butterfly Valve
Category: Vacuum Butterfly Valve
The GI-A Series High Vacuum Butterfly Valve is designed to regulate the flow of gases within vacuum pipelines. Featuring a unique clamping structure, the valve plate ensures a tight seal by compressing the sealing ring, with an additional fine adjustment function for the primary seal. The valve is equipped with a locking mechanism for secure opening and closing operations. It is suitable for use with air and non-corrosive gases.
