Vacuum Angle Valve / Vacuum Inline Valve/CF Rotatable Flanges with Copper Seal Bonnet
Vacuum Angle Valve / Vacuum Inline Valve / CF Rotatable Flanges with Copper Seal Bonnet
This series of valves is suitable for the start and stop of ultra-high vacuum systems. They are two types of vacuum block valves: manual and pneumatic. These valves offer advantages such as stability, durability, excellent sealing, and a long service life, making them one of the preferred choices in ultra-high vacuum equipment. Manual valves operate using a handwheel, which is connected to a helical transmission system to open or close the valve. The direction of operation is indicated by markings on the handle. Pneumatic valves use compressed air to operate, and when the air supply is lost, the valve plate will automatically close due to spring force. They can be used with pure air and non-corrosive gases.
Key Features:
- Designed in a standard and modular way for easy replacement and maintenance.
- Easy to clean.
- Uses stainless steel bellows and Viton O-rings, eliminating the need for lubrication.
- The internal body of the valve is welded with stainless steel, resulting in a low leak rate.
Order Information:
The order numbers for each product are listed below. Customers can search for the numbers based on the valve's operating mode and DN (diameter). For example: 2089 refers to High Vacuum Manual Block Straight Valves, DN=16mm, CF flange.
