Kf Flanges Vacuum Angle Valve Without Bellows/ Manually Operated / Vacuum Valve

KF Flanges Vacuum Angle Valve without Bellows / Manually Operated / Vacuum Valve


Kf Flanges Vacuum Angle Valve Without Bellows/ Manually Operated / Vacuum Valve
  1.  Brief Introduction
This series of valves is suitable for the start and stop operations in ultra-high vacuum systems. These are two types of vacuum block valves: manual and pneumatic. They offer numerous advantages such as stability, durability, excellent sealing, and long service life, making them a preferred choice in ultra-high vacuum equipment. Manual valves use a rotating handle to operate, with helical transmission for opening and closing. The direction of operation is indicated by markings on the handle. Pneumatic valves use compressed air for operation, and when the air supply is lost, the valve plate closes automatically due to spring force. The applicable medium includes 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 valve is welded with stainless steel, ensuring low leakage rate.
  1. Order Information
