Gate Valve , CC-35B , Manual Drive , DN35 , 1E+5-1E-7 Pa ,
Mechanical indication
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 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.
Advantages:
High reliability
Good tightness and ultra-low air bleeding rate
Stable motion, small noise and vibration
Easy installation and compact structure
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.
