Factory Precision Ultra-High Vacuum Angle Valve for Gas

August 23, 2025

Product Description

The MD-CD-J type ultra-high vacuum flapper valve is designed to control the flow of air or non-corrosive gases within high-vacuum systems. It can be operated either pneumatically or manually, offering flexibility for different applications. The pneumatic version utilizes electromagnetic switching to redirect airflow and control the cylinder movement, enabling the valve to open or close. The manual variant uses a handwheel that drives the valve via a screw mechanism, making it ideal for environments where remote control is not required. This product is particularly suitable for situations involving air, water vapor, and non-corrosive gases.
