Vacuum Angle Valve with Bellows / Manually Operated / Vacuum Valve/Kf Flanges with Copper Seal Bonnet
  1.  Brief Introduction
This series of valves is suitable for the start and stop of ultra-high vacuum systems in vacuum lines. They are two types of vacuum block valves: manual and pneumatic. These valves offer advantages such as stability, durability, excellent sealing, and long service life, making them a preferred choice in ultra-high vacuum equipment. Manual valves use a rotating handle as the actuator, with helical transmission to open and close the valve. The direction of operation is marked on the handle. Pneumatic valves use compressed air as the power source to operate the valve. When the air supply is lost, the valve plate closes automatically due to spring force. The applicable media include pure air and non-corrosive gases.
  1. Features
  1. Designed in a standard and modular way, easy to replace and maintain.
  2. Easy to clean.
  3. Equipped with stainless steel bellows and Viton O-rings, no lubrication required.
  4. The inner body of the valve is welded with stainless steel, resulting in a low leak rate.
  1. Order Information
Each product has its own order number. Customers can search based on the operating mode of the valves and the DN size. For example, an order number could be 2089. This refers to a high vacuum manual block straight valve with DN=16mm and CF flange.
