  1. Brief Introduction
This series of valves is suitable for the start and stop control in ultra-high vacuum systems. They are two types of vacuum block valves: manual and pneumatic. These valves offer advantages such as stability, durability, excellent sealing performance, and a long service life, making them one of the preferred choices for ultra-high vacuum equipment. Manual valves operate using a handwheel, which provides mechanical motion through a helical transmission system. The direction of operation is indicated by markings on the handle. Pneumatic valves use compressed air as the actuation force, and they automatically close via spring force when the air supply is lost. These valves are suitable for pure air and non-corrosive gases.
  1. Features
  1. Designed in a standard and modular way, making it easy to replace and maintain.
  2. Easy to clean and maintain.
  3. Equipped with stainless steel bellows and Viton O-rings, no lubrication required.
  4. The internal body of the valve is welded with stainless steel, resulting in a low leakage rate.
  1. Order Information
Each product has its own order number, which customers can use to search based on the valve's operating mode and DN size. For example, "2089" refers to a High Vacuum Manual Block Straight Valve with DN=16mm and a CF flange.
