Product Description

vacuum flapper valve is powered by compressed air, change the direction of air passage through the solenoid valve, push the cylinder piston, via a transmission lever (pull) motion link mechanism drives the valve plate to move axially achieve open or close the valve plate, so as to achieve the purpose of switching on or off the air flow in ultra-high vacuum system. In the structural design is reasonable, beautiful in appearance, and has a smooth operation, small size, flow rate, reliable, good sealing performance and long life, etc., it can be widely used in ultra-high vacuum equipment.
Suitable working medium is clean air and non-corrosive gases..
