Vacuum Valves with Bellows
  1.  Brief Introduction
This series valves are applicable to the vacuum line's start and stop of ultra-high vacuum system. They are two different vacuum block valves; these are manual ones and pneumatic ones. They have many advantages, such as stability, durability, great sealing, and long service life and so on, so they are one of initial optional valves in ultra-high vacuum equipment. Manual valves take manual rotating handle as motivity, and helical transmission to make valves start and stop. The direction of start and stop takes marks on the handles as the standard. Pneumatic valves take compressed air as motivity to make valves start and stop. Valve plates will close automatically depending on spring force when losing air source. Applicable medium can be pure air and non-corrosive gas.                               
  1. Features
  1. Design in a standard and moduling way. Easy to change and maintain.
  2. Easy to clean up.
  3. Adopt stainless steel bellows and viton O-ring, no lube.
  4. The inner of valves' body is welded by stainless steel and the leak rate is low.
  1. Order Information
