Features:
The Advantages of Valve Positioners
Valve positioners are devices used to control pneumatic control
valves and ensure their precise and stable operation. These devices
come with several advantages that make them popular in industries
that require control valves. Some of these advantages include:
- High-Precision Adjustment: Valve positioners use microprocessing technology to balance the
signal and feedback, ensuring high-precision adjustments for the
valves.
- Fast Response: These devices are designed to respond quickly to commands and
perform actions quickly to ensure efficient performance.
- Automatic Setting: Intelligent positioners have the function of automatic setting,
simplifying the debugging process.
- High Sensitivity: Pneumatic valve positioners can sense changes in working
conditions and adjust accordingly, ensuring stable and efficient
valve operation.
- Simple Structure: The structure of these devices is relatively simple, making them
easy to maintain, repair, and replace.
- Strong Adaptability: Valve positioners have low requirements for pneumatic control
valves and are suitable for use in various pressure ranges.
- Split-Range Control: Pneumatic valve positioners can be split-range controlled to
control multiple positioners with a single control signal.
Working Principle of Valve Positioners
Pneumatic valve positioners work by converting electrical signals
into pressure signals. These signals are used to control the
movement of the valve stem through the nozzle flapper and the film
chamber, which makes precise adjustments possible. The result is
stable and precise control of the pneumatic control valves.

Applications:
Petrochemical Industry
In the petrochemical industry, valve positioners play a crucial
role in controlling parameters such as flow and pressure. In the
production process of liquefied gas and ethylene, the significance
of valve positioners is particularly noticeable. These positioners
can meet the needs of various stages in the production process.
Sewage Treatment Industry
The sewage treatment industry uses valve positioners to regulate
the flow of sewage and clean water. This is done to ensure the
normal operation of equipment while also ensuring water quality.
Thermal Power Generation and Nuclear Power Industry
Valve positioners are extensively used in the thermal power
generation and nuclear power industries to manage fluid pipelines.
In doing so, they enhance the reliability and safety of equipment
and ensure the stable operation of power stations.
Tap Water Industry
Valve positioners are used to inspect water pipes and valves to
control water levels and water pressures. This enables real-time
monitoring through external signals.
Metallurgical Industry
Intelligent valve positioners play a crucial role in accurately
controlling valves in smelting furnaces and heat treatment
furnaces. This ensures the efficiency and safety of the smelting
process.
Pharmaceutical Industry
The pharmaceutical industry relies heavily on valve positioners for
adjusting the flow and direction of liquid medicines and solvents.
This provides precise guarantees for drug production.
Environmental Protection Field
Intelligent valve positioners are used to strictly control valves
in wastewater and waste gas treatment equipment in the
environmental protection field. This ensures the normal operation
of environmental protection facilities and compliance with emission
standards.
