Vacuum Angle Valve with Highly Chemical Resistant Manual Coating PTFE Teflon Coating

Vacuum Angle Valve with Highly Chemical Resistant Manual Coating PTFE Teflon Coating
  1. Brief Introduction
This series of valves is suitable for the start and stop operations in ultra-high vacuum systems. They are two types of vacuum block valves—manual and pneumatic. These valves offer numerous advantages such as stability, durability, excellent sealing performance, and long service life. As a result, they are often the preferred choice in ultra-high vacuum equipment. The manual valves use a rotating handle for operation, while the pneumatic ones rely on compressed air. In case of power failure, the valve plates will automatically close due to spring force. The applicable media include 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 inner body of the valve is welded using stainless steel, resulting in a low leak rate.
  1. Order Information
Each product has specific order numbers. Customers can search for these numbers based on the valve's operating mode and DN (Diameter Nominal).
