Features:

Valve positioners are important components in control systems that help in adjusting the position of valves. The features of valve positioners are crucial to ensure accurate and efficient operations in industrial processes. Some of the main features of valve positioners include:

• High-precision adjustment: Intelligent valve positioners make use of microprocessing technology to provide high-precision adjustment. This ensures a perfect balance between signal and feedback, resulting in precise control of the valve position.
• Fast response: Valve positioners have the capability for fast response and can perform actions quickly. This ensures that the valve position is adjusted in time to meet process needs.
• Automatic setting: Intelligent valve positioners have the function of automatic setting, which simplifies the debugging process. This feature is highly beneficial for complex control systems.
• High sensitivity: Pneumatic valve positioners are very sensitive to changes in working conditions. They can adjust and work stably in time, ensuring a reliable and efficient process.
• Simple structure: The structure of pneumatic valve positioners is relatively simple and easy to maintain and repair. This makes them a popular choice for many industries.
• Strong adaptability: Pneumatic valve positioners do not have high requirements for pneumatic control valves and are suitable for various pressure ranges. They can work with different types of valves, making them versatile and adaptable for different situations.
• Split-range control: Pneumatic valve positioners can be split-range controlled, and one control signal can control multiple positioners. This feature allows for better control of the valves to meet process requirements.

The working principle of valve positioners involves controlling pneumatic control valves by converting electrical signals into pressure signals. The core mechanism of pneumatic valve positioners includes the nozzle flapper and the film chamber. These components adjust the position of the valve stem through pressure sensing, which achieves precise control of the valve position.

Technical Parameters:

Applications:

Valve positioners are a vital component in the petrochemical industry as they are used to control parameters such as flow and pressure. They play a particularly important role in the production process of liquefied gas and ethylene and can meet the requirements for different stages in the process.

Valve positioners are crucial in the sewage treatment industry as they help adjust the flow of sewage and clean water. This ensures that equipment functions optimally and water quality is maintained.

Valve positioners are widely used in the thermal power generation and nuclear power industries. They help to control fluid pipelines, improve equipment reliability and safety, and ensure the plant operates smoothly.

Valve positioners are used extensively in the tap water industry. They are vital in inspecting water pipes and valves, controlling water levels and water pressure, and monitoring everything in real-time through external signals.

Intelligent valve positioners play a pivotal role in the metallurgical industry. They are used to accurately control valves in smelting furnaces and heat treatment furnaces to ensure the efficiency and safety of the smelting process.

In the pharmaceutical industry, valve positioners are of utmost importance for adjusting the flow and direction of liquid medicines and solvents. This helps provide precise guarantees for drug production.

Intelligent valve positioners play a crucial role in the environmental protection field. They strictly control valves in wastewater and waste gas treatment equipment, thus ensuring the normal functioning of environmental protection facilities and compliance with emission standards.
