Vacuum Angle Valve / Vacuum Inline Valve with ISO Flanges


Vacuum Angle Valve / Vacuum Inline Valve with ISO Flanges
  1. Brief Introduction
This series of valves is suitable for the start and stop functions in ultra-high vacuum systems. They are two types of vacuum block valves: manual and pneumatic. These valves offer multiple advantages such as stability, durability, excellent sealing performance, and a long service life, making them one of the preferred choices in ultra-high vacuum equipment. Manual valves operate using a rotating handle, while pneumatic valves use compressed air to control the opening and closing. When the air supply is lost, the valve plates close automatically due to spring force. The valves are compatible with pure air and non-corrosive gases.
  1. Features
  1. Designed in a standard and modular way for easy replacement and maintenance.
  2. Easy to clean and maintain.
  3. Equipped with stainless steel bellows and Viton O-rings, no lubrication required.
  4. The internal body is welded from stainless steel, ensuring a low leak rate.
  1. Order Information
Each product has a specific order number. Customers can search based on the valve's operation mode and DN size. For example:
