Where are pneumatic butterfly valves used?

Pneumatic butterfly valve is also called pneumatic control butterfly valve. Pneumatic actuator principle structure double-acting actuator operation principle diagram (normally closed type DC). In industrial control, the pneumatic actuator principle structure drives the air source from port A, the gear shaft rotates counterclockwise, and the valve Open the pneumatic actuator principle structure in the industrial control to drive the air source from port B, the gear shaft rotates clockwise, and the valve closes.

Pneumatic butterfly valve can be used for on-off control of low-pressure pipeline media. Butterfly valve refers to a kind of valve whose closing part (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

Pneumatic butterfly flying is suitable for cutting off fluids. Pneumatics are used in locations that require unsafe environments or a high degree of automation. Butterfly valves are suitable for pipelines transporting various corrosive and non-corrosive fluid media in engineering systems such as generators, coal gas, natural gas, liquefied petroleum gas, city gas, cold and hot air, chemical smelting and power generation and environmental protection, and are used for regulation and interception. The flow of the medium. It is widely used in the control terminal of many automatic control industrial pipelines in chemical industry, electric power, petroleum, chemical industry, natural gas refining, papermaking, pharmaceutical and so on. It controls the input of dry and lubricated gas to pneumatics through positioners, solenoid valves or other equipment The cylinder of the device is a pneumatic device that turns according to the given requirements to realize the opening and closing and adjustment of the pneumatic butterfly valve. It can also be connected to the field bus with an intelligent positioner to detect the state of the butterfly valve and provide diagnosis.
