Pneumatic soft seal butterfly valve D671X

In many factories and production workshops, equipment maintenance and upkeep have been required to be institutionalized and standardized,Pneumatic Butterfly ValveAlthough it is just an ordinary valve device, it is essential to take necessary maintenance measures in daily life to avoid affecting its use and extend its service life. So, what are the maintenance measures?

1、 Regular maintenance

Although it may not require daily maintenance, in order to ensurePneumatic Butterfly ValveBeing able to meet usage needs without sudden strikes catching people off guard, it is not possible to carry out daily maintenance. Regular personnel inspections are necessary. The regular maintenance of pneumatic butterfly valves includes checking the working condition of the valve, inspecting the corrosion of valves used for controlling and processing chemical media fluids, checking for noise during operation, ensuring good sealing of the valve, and checking for fluid leakage when the valve is closed. For pneumatic butterfly valves used in hydropower plants, it is also necessary to check whether the valve switch is blocked. If there is a blockage, it should be cleaned in a timely manner, otherwise it will greatly affect the effectiveness of the pneumatic butterfly valve.

2、 Maintenance and repair

Mechanical equipment malfunctions are inevitable, except for regular maintenancePneumatic Butterfly ValveIn addition to cleaning, it is also necessary to ensure the good sealing of the valve, and regularly verify the performance of the pneumatic butterfly valve. If possible, it is best to conduct equipment and instrument testing on the pneumatic butterfly valve. In the event of a malfunction, it is important to promptly seek professional maintenance personnel to repair and replace damaged components. In addition, proactive maintenance work before the malfunction is also crucial.

Pneumatic Butterfly ValveThe service life is related to the quality of the product itself, whether the later maintenance is in place, and whether the correct usage method is followed.

Basic InformationProduct information

Product Name: Pneumatic Soft Seal Butterfly Valve

Product model: D671X

Product Introduction:

Advantages of pneumatic soft seal butterfly valve: 1. Simple structure, low flow resistance coefficient, flow characteristics tend to be straight, and no debris will be trapped. 2. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage points. 3. Divided into pneumatic clamp type soft seal butterfly valves and pneumatic flange soft seal butterfly valves, to meet different pipeline requirements. 4. The seals can be replaced, and the sealing performance is reliable, achieving bi-directional sealing with zero leakage. 5. The sealing material is resistant to aging, corrosion, and has a long service life.

Product FeaturesProduct characteristics

Pneumatic soft seal butterfly valve is a type of centerline butterfly valve with good corrosion resistance and sealing performance. It is generally divided into flange or clamp type connections and can be used in normal temperature and pressure environments with corrosive media and high leakage requirements. The pneumatic soft seal butterfly valve adopts a sealing structure, and the sealing materials include rubber, polytetrafluoroethylene, etc. The leakage can reach zero leakage. Due to structural limitations, pneumatic soft sealed butterfly valves are not suitable for industries with high temperature, high pressure, and wear resistance. They are only suitable for use in room temperature environments, low pressure, medium pressure, and other places for switching off and regulating flow.

Pneumatic soft seal butterfly valveadvantage

1. The structure is simple, the flow resistance coefficient is small, the flow characteristics tend to be straight, and there will be no debris trapped.

2. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage points.

3. Divided into pneumatic clamp type soft seal butterfly valves and pneumatic flange soft seal butterfly valves, to meet different pipeline requirements.

4. The seals can be replaced, and the sealing performance is reliable, achieving bi-directional sealing with zero leakage.

5. The sealing material is resistant to aging, corrosion, and has a long service life.

　　Can be equipped with accessories

1. Cut off accessories: single electric control solenoid valve, dual electric control solenoid valve, limit switch feedback device.

2. Adjustable accessories: electrical locator, pneumatic locator, electrical converter.

3. Air source processing accessories: air filter pressure regulating valve, air source processing triad.

4. Using an electric pneumatic valve positioner, powered by electrical signals and compressed air, it receives 0-10mA DC or 4-20mA DC current signals from the control system input. The regulator converts the compressed air into a gas source pressure signal input and output, changing the rotation angle of the valve plate (any angle from 0-90 °), and has good control over flow rate and other parameters.

5. Adopting electromagnetic steering valve and valve position feedback device, powered by AC220V or DC24V power supply voltage and compressed air, to achieve rapid two position cut-off control of fluid medium. The pneumatic actuator adopts a piston type cylinder and a curved arm conversion structure, which has the characteristics of large output torque, small volume, fully sealed waterproof design, and high IP protection level.

6. The cylinder block adopts a mirror cylinder, oil-free lubrication, low friction coefficient, corrosion resistance, and has super durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft is not worn.

　　The difference between pneumatic soft seal butterfly valve and pneumatic hard seal butterfly valve:

1. Soft sealed butterfly valves are mostly of medium line type, while hard sealed butterfly valves are mostly of single eccentric, double eccentric, or triple eccentric structure.

2. Soft seals are used in ambient temperature environments. Hard seals can be used in environments such as low temperature, room temperature, and high temperature.

3. Soft seals are used for low pressure to atmospheric pressure, while hard seals can also be used for medium to high pressure.

4. Soft sealed and triple eccentric hard sealed butterfly valves have better sealing performance, and triple eccentric butterfly valves can maintain good sealing in high-pressure and high-temperature environments.

5. The advantage of soft sealed butterfly valves is good sealing performance, but the disadvantages are easy aging, wear, and short service life.

6. Hard sealed butterfly valves have a long service life, but their sealing performance is relatively poor compared to soft seals.
