Pneumatic Butterfly Valve: Working Principle and Use Occasions
Pneumatic butterfly valve is a common equipment in fluid control system. In this article, DELCO Valve will share and discuss the working principle and advantages of pneumatic butterfly valves as well as common applications, so that we can understand more about pneumatic butterfly valves.
What is Pneumatic Butterfly Valve?
Pneumatic Butterfly Valve is a kind of valve controlled by pneumatic actuator to switch on and off, and its core component is a disc-shaped butterfly plate, which is rotated to regulate or cut off the fluid flow. It combines the compact design of a butterfly valve with the automation features of a pneumatic actuator, and is suitable for applications requiring fast response and remote control.
Working Principle of Pneumatic Butterfly Valve
Pneumatic butterfly valves control the position of the valve through a pneumatic actuator. The pneumatic actuator receives the pneumatic signal from the control system and controls the opening and closing of the valve by controlling the inlet and outlet of the air source. When the signal from the air source is sent to the pneumatic actuator, the air pressure inside the pneumatic actuator will act on the valve stem to make the valve stem rotate, thus changing the degree of opening of the valve. Forward rotation can make the valve open, reverse rotation can make the valve close. When the valve is open, the fluid can pass through the valve smoothly, realizing the smoothness of the pipeline. When the valve is closed, the valve flap is in contact with the sealing surface, preventing the fluid from passing through. By controlling the degree of opening of the valve, the flow of fluid in the pipeline can be adjusted to realize the control and regulation of flow.
Advantages of pneumatic butterfly valve
- Fast response: pneumatic actuator provides fast switching action, which is suitable for occasions requiring emergency cut-off or frequent operation.
- Compact structure: butterfly valve is simple in design and occupies little space, suitable for systems with limited installation space.
- Small fluid resistance: pneumatic butterfly valve has a large effective circulation area when fully open, small fluid resistance and strong circulation capacity. So the pneumatic butterfly valve can provide higher flow rate in large caliber pipeline, reduce energy consumption, improve efficiency and reduce operating costs.
- Good sealing performance: there are various choices of sealing materials for pneumatic butterfly valves, including nitrile rubber, fluorine rubber, etc. These materials can provide good sealing performance and ensure reliable sealing under various temperature and pressure conditions.
- Wide range of application: suitable for a variety of fluids such as water, gas, steam, corrosive media.
Pneumatic butterfly valve use occasions
- Water treatment industry: used for sewage treatment, water purification plants and water supply systems in the flow control.
- Chemical industry: used to transport corrosive media such as acids, alkalis, solvents and other corrosive media piping system.
- Food and beverage industry: used in pipelines for conveying food-grade media such as milk, juice, beer and so on.
- Pharmaceutical industry: used for fluid control in the process of pharmaceutical production.
- HVAC system: used for hot and cold water conditioning in HVAC system.
- Energy industry: used for natural gas, oil and other energy transportation pipelines.
Frequently Asked Questions
- Can pneumatic butterfly valve be used for high temperature medium?
Yes, but you need to choose high temperature resistant materials (such as stainless steel) and sealing materials (such as PTFE).
- How fast is the switching speed of pneumatic butterfly valve?
The switching speed depends on the specifications of the actuator and the pressure of the air source, and is usually completed within a few seconds.
- How is the sealing performance of pneumatic butterfly valve?
Pneumatic butterfly valves with high quality sealing materials (such as rubber or PTFE) have excellent sealing performance and low leakage rate.
- Can pneumatic butterfly valve be operated manually?
Some pneumatic butterfly valves are equipped with manual operation device, which can manually open and close the valve in case of power failure or air failure.
