Vacuum Angle Valve with Bellows / Manually Operated / Vacuum Valve / KF Flanges with Copper Seal Bonnet
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, and a long service life, making them one of the preferred choices in ultra-high vacuum equipment. Manual valves are operated using a rotating handle, which uses a helical mechanism to open and close the valve. The direction of operation is indicated on the handle. Pneumatic valves use compressed air to operate, and the valve plates will automatically close due to spring force when the air supply is lost. The applicable media include pure air and non-corrosive gases.
Features:
- Designed in a standard and modular way, making it easy to replace and maintain.
- Easy to clean.
- Uses stainless steel bellows and Viton O-rings, requiring no lubrication.
- The inner body of the valve is welded with stainless steel, resulting in a low leak rate.
Order Information:
Each product has specific order numbers that customers can refer to based on the valve's operating mode and DN size. For example, "2089" refers to a high vacuum manual block straight valve with DN=16mm and CF flange.
Below is a table showing the order numbers, weights, and dimensions for different sizes:
| DN (mm) | Manual Order No. | Pneumatic Order No. | Manual Weight (kg) | Pneumatic Weight (kg) |
|---------|------------------|---------------------|--------------------|------------------------|
| 16 | 2089 | 2297 | 0.50 | 0.70 |
| 25 | 2090 | 2298 | 1.80 | 1.70 |
| 40 | 2091 | 2299 | 2.20 | 2.10 |
| 50 | 2092 | 2300 | 2.70 | 3.55 |
