Pneumatic Actuated Butterfly Valve
The pneumatic actuated butterfly valve is widely used in industrial applications, including clean and waste water control, HVAC, chemicals, etc. A pneumatic butterfly valve is consist of double acting or single acting pneumatic actuator and butterfly valve, connection type has water type and flange type. The pneumatic actuator butterfly valve has a simple structure, moderate size, and light weight. Stable performance. It can be equipped with some accessories, such as positioner, limit switch, hand wheel, solenoid valve, air preparation units, etc.

Features
1. Simple and compact construction, quick 90 degrees of on-off operation. Minimized operating torque and energy saving.
2. Bubbles-tight sealing with no leakage under the pressure test.
3. The connection of the driven part conforms to ISO5211.
4. Wide selection of materials applicable for various mediums.
5. The valve body and disc are accurately machined, which results in low operating torque and long service life and reliability.
6. Can be disassembled. Material-specific recycling is possible.
7. Can be installed at the end of the pipe for lugged type butterfly valve.
