Small flapper valve

Flapper valve CD-J ultra-high-altitude flapper valve for turning on or off the line of ultra-high vacuum system airflow, pneumatic or manual drive. Pneumatic valve is to change the direction of air flow through the solenoid valve to control the movement of the cylinder, to open and close the valve; manual valve is manually rotating the handle as the driving force to achieve the valve opening and closing by a screw drive. It is suitable for medium air and non-corrosive gas situation.   Features: Modular design, compact structure, beautiful appearance, light weight. Mechanical wear, long service life. Welded bellows seal, reliable sealing. Stainless steel welded inside the body,  small leak rate.
