IRIE KOKEN’s high-vacuum angle valves are long lifetime vacuum valves with built-in formed or welded bellows with a long performance record of success. The valves include three types of connection: an easy-to-handle NW-KF flange that conforms to ISO standards, a CF (conflat) flange that can also be used for ultra-high vacuums or toxic gases, and a common vacuum flange that conforms to JIS. These are available in both manual and automatic (pneumatic) series models.
The LX Series (guaranteed life of 1 million repetitions) has also been added as a standard product to meet demands for longer life products.
