Vacuum Angle Valves with KF/CF/ISO-F Flanges
Vacuum angle valves are essential components in ultra-high vacuum systems, designed for the reliable start and stop of vacuum lines. These valves come in two types: manual and pneumatic. They offer stability, durability, excellent sealing performance, and a long service life, making them ideal for use in high-vacuum equipment. Manual valves operate using a rotating handle, while pneumatic valves use compressed air to control the opening and closing mechanism. In case of power failure, the valve plates will automatically close due to spring force. The valves are suitable for pure air and non-corrosive gases.
Key Features:
- Modular design for easy installation and maintenance
- Easy to clean and maintain
- Utilizes stainless steel bellows and Viton O-rings, eliminating the need for lubrication
- Inner body is welded with stainless steel, ensuring low leak rates
Order Information:
Each product has a specific order number that customers can use to identify the type of valve and its nominal diameter (DN). For example, 2089 refers to a high vacuum manual block straight valve with DN=16mm and CF flange.
