Factory Precision Ultra-High Vacuum Angle Valve for Gas
Product Description
The MD-CD-J type ultra-high vacuum flapper valve is used to switch on or off the air flow in the ultra-high vacuum system piping. There are pneumatic and manual drive methods. The pneumatic valve controls the movement of the cylinder by changing the direction of the air flow through electromagnetic commutation to reach the opening and closing of the valve. The manual valve uses the manual rotation of the handle as the power to achieve the opening and closing of the valve through the screw drive. Suitable for occasions where the medium is air and non-corrosive gas.
Features
Modular design, compact structure, beautiful appearance, light weight;
Small mechanical wear and long service life;
The shaft seal adopts welding bellows, and the seal is reliable;
The valve body adopts stainless steel internal welding, and the leakage rate is small.
