Butterfly Valve AXONⅡSeries
1,000,000 cycles and two years guarantee
High performance
- ◇ 1,000,000 cycles and two years guarantee
Two worth works with one valve
- ◇ It can be operated in the 2 position of the valve opening is 0 degrees to 45 degrees and 90 degrees ( fully open ) , so it is possible for throw exhaust and high speed exhaust at one valve.
- ◆ Fully closed and fully open for air cylinder , and the valve opening degree is a two-step structure of which is provided an air cylinder that can be set to any in the range of 0 to 45 degrees .
Adopt a double cylinder system of patent mechanism ( Pneumatic type )
- ◇ By adopting a double air cylinder method, an air thrust doubles during valve fully open, More impact force by the air damper mechanism have been alleviated.
- ◆ Double cylinder system is provided a bypass flow and the assist chamber in the cylinder
- ◇ The bypass flow is connected with the assist chamber from the valve fully open side cylinder chamber The diameter is reduced enough than the diameter of the air inlet.
- ◆ Piston movement will begin before sufficient air is supplied to assist chamber by this mechanism.
When the valve body is fully opened, the pressure in the assist chamber becomes negative, so assist chamber will alleviate the impact force as air cushion.
Unchanged price , The price that it is easy to adopt
- ◇ New series can be immediately exchange for the old series and the same dimensions.
- ◆ It’s the price quite more profitable than the price for 2 valves, so it’ll be cost cutting of an exhaust system.

How to adjust opening angle of Valve Disc
By pulling out the Adjuster Flange from the cylinder 2 as shown above , the opening angle of valve Disc can be set in the range of 45°～0°.
The relation between Y and the valve opening angle is shown in Table-1. This table was prepared by using calculated values, so it may sometime differ from an actual valve opening angle.

＊ The valve opening 0° is an adjustment of cylinder 2, and it is unrelated to the switching action of cylinder 1.
＊ Y denotes the length when Lock-nut was fixed after Adjuster Flange was pulled out.
How to connect air piping
Connect the air pressure of 0.4 ~ 0.6MPa G to Inlet a, b, c.
Table2 shows relationship between the valve state and the combination of whether air is let IN or OUT at each Air Inlet.
