  1. Brief Introduction
This series of valves is designed for use in ultra-high vacuum systems, serving as a reliable means to start and stop vacuum lines. These are two types of vacuum block valves: manual and pneumatic. They offer excellent stability, durability, strong sealing, and long service life, making them an ideal choice for ultra-high vacuum equipment. Manual valves operate using a rotating handle, which uses a helical mechanism to open or close the valve. The direction of operation is indicated by markings on the handle. Pneumatic valves, on the other hand, are operated by compressed air, and automatically close via spring force when the air supply is lost. They are suitable for pure air and non-corrosive gases.                               
  1. Features
  1. Designed with standard and modular construction, allowing 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 inner body of the valve is welded with stainless steel, ensuring a low leak rate.
  1. Order Information
Each product has a unique order number that customers can use to search based on the valve type (manual or pneumatic) and the nominal diameter (DN). For example, "2089" refers to a high-vacuum manual block straight valve with DN=16mm and a CF flange. Below is a detailed table showing the order numbers, weights, and specifications for different sizes:
