Pneumatic Butterfly Valve -FAQ
A pneumatic butterfly valve is made of a pneumatic actuator and a butterfly valve. The butterfly valve is a pneumatic valve that uses a circular butterfly plate that rolls with the valve stem to achieve opening and closing. It is mainly used as a cut-off valve. It can also be provided to have the function of regulating or segmenting the valve and the regulation. Now the butterfly valve is low pressure and large.
A pneumatic valve is a motorized valve whose closing and opening mechanism is operated by a compressed gas (usually air) actuator. In recent years the use of butterfly valves has become increasingly widespread. The butterfly valve material can be divided into stainless steel butterfly valve, cast iron butterfly valve, cast steel butterfly valve, and plastic butterfly valve. BCST is one of the best manufacturers of differential pressure gauges and supplies an amount of material adjustment of the allowable level of instantaneous consumption. According to the seals of butterfly valves, butterfly valves can be divided into soft seal butterfly valves and hard seal butterfly valves. At the same time, according to the eccentric type, butterfly valves are divided into single eccentric type, double eccentric type, and triple eccentric type.
What are the areas of application of a Pneumatic butterfly valve?
Pneumatic valves are used in the development of automation or remote-control systems. As such, they are found in all industry sectors, machine tools, chemicals, petrochemicals, medical, pharmaceuticals, food, transport, etc.
They also find applications in communities: hot water, air or steam heating, air conditioning, transport of liquid or gaseous fuels, and firefighting.
Single-acting cylinder
In the single-acting cylinder technique, the cylinder’s single air inlet (located on one end) only allows the piston to push in one direction (opening or closing). The reverse movement is purely mechanical: a spring, compressed during the driving phase, relaxes as soon as the pressure is released.
Double-acting cylinder
In the double-acting technique, the jack cylinder has an air inlet at each end. It is, therefore, possible, at leisure, to close, open or regulate the valve’s flow rate by injecting air at one of the ends. The thrust power is independent of maneuver direction, but the management of movements is more complex.
What is the Behavior of the pneumatic valve in the event of air failure?
The elementary rules of safety impose to choose with discernment the status of opening of the pneumatic valve in the event of engine air failure. The role of the transported fluid often imposes this choice. In the event of a lack of air, it is preferable, for example, to close the cut-off valve of a fuel supply circuit.
If the valve blocks a cooling circuit, it is, on the contrary, more prudent that it remains open. A third option consists in avoiding a sudden variation in the flow rate by blocking the device in the position it occupies when the breakdown occurs.
What are the Advantages of the Pneumatic butterfly valve?
We keep close contact with customers, and according to customers’ needs, we develop and produce this Lugged Pneumatic Butterfly Valve for your choice. The advantages of lugged butterfly valves include ease of installation and ease of use.

- Good sealing performance
- Long service life
How to maintain the pneumatic butterfly valve to increase its service life？
The pneumatic butterfly valve is just an ordinary valve device; in order not to affect the operation and prolong the service life, the necessary maintenance is carried out daily. Measurements are essential. So what are the maintenance measures?
Regular maintenance is certainly not necessary for daily maintenance. Still, to ensure that the pneumatic butterfly valve can meet the needs of the operation, and will not be taken by surprise, it is not possible to carry out the daily maintenance, and it is necessary to organize the personnel to check regularly.
Regular maintenance of pneumatic butterfly valves includes whether the valve is operating normally. Valves used in the control and disposal of fluids and chemical fluids should be checked for corrosion.
If there is noise during operation, if the valve is tight, if there is fluid leakage when the valve is closed, etc., the pneumatic butterfly valves used in hydropower plants should likewise be checked for blockage at the valve switch. If there is a blockage, it should be cleared in time; any other way, it will influence the application impact of the pneumatic butterfly valve.
It is inescapable that the upkeep and fix of mechanical gear will have weaknesses. As well as routinely halting the cleaning of the pneumatic butterfly valve, it is likewise essential to guarantee that the valve’s fixing execution is excellent, and the presentation of the pneumatic butterfly valve should be checked periodically.
The pneumatic butterfly valve suspends equipment and instrument testing. If there are any shortcomings, find maintenance personnel to repair and replace the damaged parts in time. In addition, predictive maintenance work before faults is also significant.
What are the requirements for the installation of a pneumatic butterfly valve?
- Before installation, check that there are no missing parts of the butterfly valve, that the type is correct, check that there is no debris in the valve body and that there is no blockage in the solenoid valve and the muffler.
- Put the valve and the cylinder in a closed state.
- Install the cylinder on the valve (the direction of the device is parallel or straight to the valve body), then check whether the screw holes are aligned; there will not be too much error. If there is a little error, roll the cylinder body and tighten the screws.
- After the installation is completed, debug the butterfly valve. The solenoid valve needs to be manually opened and closed during operation debugging (manual operation after the solenoid valve coil is powered off cannot be helpful), and study the opening and closing of the butterfly valve.
- If the valve is found to be a little difficult at the beginning of the opening and closing process during the debugging operation, and this is normal, you should reduce the cylinder stroke (the stroke adjustment screws at both cylinders ends must be adjusted inward at the same time, and the valve must be operated in the open position during adjustment.
What are the pneumatic butterfly valve design and options?
Simplicity is the hallmark of a pneumatic butterfly valve. It consists of a cylindrical body through which the working medium flow is carried out. Inside the space of the case is the disk itself. It is the moving part.
The disc can perform rotational movements around the axis, making contact with the body’s surface with a seal, thus blocking the through-hole. The shape of the product may vary in appearance. It can be a disk, either flat or lenticular. Butterfly valves are used for working environments of different nature. Exceptional protection against corrosion is sometimes required, as well as minor wear of structural parts.
Most often, for these purposes, system parts are made of stainless steel with a seal in the form of a rubber ring. Conventional valves that do not protect against corrosion and wear are made of carbon or alloy steel. In any case, the body is cast iron.
As an option with protection against chemical influences, devices are equipped with elastomeric or rubber inserts placed in the case, and sometimes the disc’s surface is coated with polymeric substances.
This protection easily replaces the use of additional pads. As for the connection options with the pipeline, the most common is the coupling. Along the edge of the body are holes into which unique studs are inserted, connecting the pipeline flanges. There are also options for manufacturing structures with their flanges. With their help, the valve is connected to the flanges of the pipeline system.
Conclusion
The main advantages of pneumatic butterfly valves are simple structure, small size, lightweight, and low cost. This feature of butterfly valves is particularly noteworthy. It is installed in a dark tunnel at high altitudes. It is convenient to control and operate through a two-position five-way solenoid valve, and it can also adjust the media flow. A pneumatic butterfly valve, also known as a globe valve, is a simple structure conditioning valve. The butterfly valve, which can be used to switch the low-pressure pipeline support, refers to the closing part (disk or butterfly plate) as a disc, which rotates around the valve shaft to achieve the opening and closing. A kind of valve. Valves can control the flow of various fluids such as air, water, steam, corrosive media, mud, oil, liquid metal, and radioactive media. The main effect of blocking and throttling on the pipeline. The opening and the closing part of the butterfly valve is a disc-shaped butterfly plate.
