Updated type of Ultrahigh Vacuum Gate valve are ultra think type gate valves developed based on original valve, are applicable for ultrahigh vacuum.

It has DN320 ISO- K, ISO-F and CF standard Flange, and application range is wide from 1E+5 to 1E-7 Pa.


Exteranl surface of valve adopts silver grey matte finishing. Main parts and components such valve boday and plate are made of 304 stainless steel with very low air bleeding amount, and drive component which realizes movement of valve body adopts 316L stainless steel welded beloows. Imported fluorine rubber gasket with very low air bleeding amount is used for sealing of valve plate. If baking is required, please refer to the Performance index. So that it prevents the valve from being damaged or reliability of valve seal from being affected.



1. High reliability

2. Good tightness and ultra-low air bleeding rate

3. Stable motion, small noise and vibration

4. Easy installation and compact structure

5. Elegant appearance


Structure features:

1. Stainless steel whole internal welding valve body, with good sealing, small volume, light weight and elegant appearance.

2. Valve spool assembly has simple structure, less welding parts, simple welding process, convenient assembly and debugging, and dual-rail roller bearing mechanism is used for its axial movement, with stable movement and high steering accuracy.

3. Seal plate and support plate adopt whole plate structure, and have even support force distribution and good rigidity.

4. When the valve is opened, the support steel ball is located at steel ball sleeve hole and steel ball groove of seal plate and support plate; when the valve is closed, the steel ball will be pushed out from the groove and located at the plane of seal plate and support plate, playing a role of splitting and supporting.

5. Drive mechanism adopts planar linkage mechanism, with simple structure, large bearing capacity and high action stability. Cylinder (or handle) is located at axle wire of valve.

6. Drive shaft (link) is sealed with 316L stainless steel welded bellow, with good sealing performance, and can be installed at any position.

7. The user can select manual, pneumatic or electric mode as required. Manual valve has simple structure, which operates easily and flexibly; and pneumatic and electric valve are suitable for automatic control.

8. The series gate valve have three connection methods in vacuum system: CF flange sealed with copper washer and ISO-F and ISO-K flanges sealed with fluorine rubber ring.
