Name:Stainless Steel Manual High Vacuum Flapper Valve KF CF Bellows Angle Valve

     GD high vacuum flapper valve is used to put through or cut off the airflow in vacuum pipeline. According to its shaft seal structure, high vacuum flapper valve is classified into GD-J rubber shaft seal type and GD-J(b)bellows shaft seal type. According to its put-through type, it is classified into GD-J angle type and GD-S three-way type with prepumping.

    GDQ-J/KF series pneumatic high vacuum baffle valve is sealed with fluorine rubber shaft seal, which is a vacuum valve used to open or cut off the air flow in the vacuum system. The valve is powered by compressed air. It is executed by the cylinder, and the electromagnetic directional valve changes the direction of the gas path to drive the valve rod to move up and down to achieve the purpose of opening or closing the valve plate. The valve has the advantages of reliable performance and long life. The valve has the functions of normally open and normally closed, and can be equipped with magnetic switch signal control and explosion-proof solenoid valve device. The applicable working medium is air and non-corrosive gas.
