The working principle and advantages of ventilation butterfly valves
The ventilation butterfly valve is a common pneumatic regulating device, which adopts a butterfly structure and controls the gas flow by adjusting the opening angle of the butterfly plate.
Its working principle is simple yet efficient, with the following advantages:
1, Energy saving and efficient: The ventilation butterfly valve can adjust the angle of the butterfly plate at any time during use to reduce gas loss and effectively save energy consumption.
2, Easy to use: The ventilation butterfly valve has a simple structure and is easy to operate. It can adjust the gas flow rate at any time to achieve the expected effect.
