 Kf/CF/Lf Stainless Steel High Vacuum Angle Valve
  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 numerous advantages such as stability, durability, excellent sealing, and long service life, making them a top choice for ultra-high vacuum equipment. Manual valves use a hand-operated handle with helical transmission for operation, while pneumatic valves use compressed air for actuation. When the air supply is lost, the valve plates close automatically due to spring force. The applicable media include pure air and non-corrosive gases.                               
  1. Features
  1. Designed in a standardized and modular way, 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 inner body of the valve is welded with stainless steel, ensuring low leakage rate.
  1. Order Information
Each product has its own order number. Customers can search based on the valve's operating mode and DN size.
