Vacuum Angle Valve with Highly Chemical Resistant Manual Coating PTFE Teflon Coating
Vacuum Angle Valve with Highly Chemical Resistant Manual Coating PTFE Teflon Coating
This series of valves is suitable for the start and stop of ultra-high vacuum systems in vacuum lines. These are two types of vacuum block valves: manual and pneumatic. They offer numerous advantages, such as stability, durability, excellent sealing performance, and a long service life, making them one of the primary choices for ultra-high vacuum equipment. Manual valves use a manual rotating handle as the actuation mechanism, with helical transmission to open and close the valve. The direction of operation is determined by markings on the handle. Pneumatic valves use compressed air as the actuation source to control the opening and closing of the valve. When the air supply is lost, the valve plates will automatically close due to spring force. The applicable medium can be pure air and non-corrosive gases.
Features:
- Designed in a standardized and modular way, making it easy to replace and maintain.
- Easy to clean.
- Uses stainless steel bellows and Viton O-rings, eliminating the need for lubrication.
- The inner body of the valve is welded with stainless steel, ensuring a low leak rate.
Order Information:
Each product has specific order numbers. Customers can search for these numbers based on the valve's operating mode and DN size. For example: 2089 - High Vacuum Manual Block Straight Valves, DN=16mm, CF flange.
