Angle Valves - CF Rotatable Flanges with Copper Seal Bonnet Vacuum Valve
  1. Brief Introduction
This series of valves is suitable for the start and stop operations in ultra-high vacuum systems. They are two types of vacuum block valves: manual and pneumatic. These valves offer numerous advantages such as stability, durability, excellent sealing performance, and long service life, making them a preferred choice for initial use in ultra-high vacuum equipment. Manual valves operate using a manual rotating handle, utilizing helical transmission to open and close. The direction of operation is indicated by markings on the handles. Pneumatic valves use compressed air as the actuating force, and when the air supply is lost, the valve plates will automatically close 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 change and maintain.
  2. Easy to clean and maintain.
  3. Equipped with stainless steel bellows and Viton O-rings, no lubrication required.
  4. The inner body of the valves is welded with stainless steel, resulting in a low leak rate.
