Where are pneumatic butterfly valves used
Pneumatic butterfly valve, also known as pneumatic control butterfly valve, is a valve whose closed part (butterfly plate or butterfly plate) is a butterfly plate. It rotates around the valve axis to open and close, and it is mainly used to intercept and save the pipeline. It can be used for switch control of low-pressure pipeline media. The opening and closing part of the pneumatic butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or conditioning. In industrial control, the principle structure of the pneumatic actuator drives the air source and the gear shaft to rotate counterclockwise from the start port, and the valve opens. The driving air source is input from the closed port, the gear shaft rotates clockwise, and the valve is closed.
Pneumatic butterfly valves are suitable for blocking fluids for use in risky environments and where a high degree of automation is required. Pneumatic butterfly valves transport various corrosive and non-corrosive fluid media in engineering systems such as coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical industry, power generation, and environmental protection, and are suitable for various pipeline conditioning and blocking fluids.
Many control terminals for automated control of industrial pipelines are widely used, and the dry and smooth gas is input into the air pressure through the control of the positioner. The cylinder of the pneumatic butterfly valve is a pneumatic device that rotates as required to complete the opening and closing and conditioning operations of the butterfly valve. Users can also use the intelligent locator to connect to the field bus to detect and diagnose the condition of the pneumatic butterfly valve.
Pneumatic butterfly valve is a commonly used valve control instrument. It uses a circular butterfly plate that rolls with the valve stem for opening and closing, and the pneumatic valve that completes the activation action is mainly used as a cut-off valve. There are many types of pneumatic butterfly valves. I will introduce the classification of pneumatic butterfly valves in detail, hoping to help us.
Pneumatic flange butterfly valve, pneumatic flange butterfly valve This product is composed of rubber sealing butterfly valve and carbon steel or stainless steel valve plate and valve stem. It is suitable for the effect of conditioning and intercepting media in water supply and drainage and gas pipelines with a temperature of ≤80～120℃, such as food, chemical, petroleum, electric power, light textile, papermaking, etc.
