Description
Product Description
The V18345 – 1020120001 is an intelligent valve positioner of ABB. It is mainly used to drive pneumatic actuators of linear – stroke valves1. Its core function is to accurately control the opening and closing of valves by receiving control signals. It can convert the input electrical signal into a corresponding pneumatic signal to drive the valve actuator to move, thereby achieving precise control of the valve position.
This product has the advantages of easy operation and high intelligence1. It features automatic commissioning, which allows all parameters to be automatically set within three minutes after connecting the signal source1. As a truly intelligent instrument, it has various optional communication protocols, such as the HART protocol in the basic type, which facilitates on – site manual operation1. It can also provide self – diagnosis information at any time, including cumulative travel, out – of – limit, air leakage at the regulating valve diaphragm joint, valve locking, etc., helping to promptly detect valve abnormalities1. In addition, it offers protection functions for valve position in case of signal loss, enhancing system safety1.
Product Parameters
- Power supply: Usually operates within a certain voltage range, such as 24V DC.
- Signal input: Accepts 4 – 20mA current signal as the input control signal.
- Communication protocol: The basic type adopts the HART protocol, and there are also other optional communication protocols such as PROFIBUS PA and FOUNDATION Fieldbus for different models.
- Interface type: It has standard interfaces for connecting to valve actuators and other devices, such as 1/2 – 14NPT connection interfaces.
- Compatibility: Compatible with a variety of ABB – brand valve actuators and can also work with some third – party actuators that meet the relevant standards.
Advantages and Characteristics
- High reliability: It can continuously and stably operate in harsh industrial environments. For example, in a chemical plant, it has withstood the test of long – term use and has rarely had failures, ensuring the normal operation of the valve control system.
- Easy integration: With its modular design, it is easy to install and integrate with existing control systems. It can be quickly connected to the control system through standard communication protocols and interfaces, reducing the difficulty and time of system integration.
- Intelligent diagnosis: The built – in intelligent diagnosis function can timely detect various faults of the valve and send out alarm signals, which helps maintenance personnel quickly locate and solve problems, reducing maintenance costs and downtime.
Application Areas and Application Cases
- Application areas: Widely used in industries such as manufacturing, energy, and chemical engineering. In the manufacturing industry, it is used to control the valves in the production line to ensure the accurate supply of raw materials and the smooth progress of the production process. In the energy industry, it is used in the control of valves in power plants and oil and gas fields to achieve the efficient transportation and use of energy.
- Application case: In a certain oil refinery, the V18345 – 1020120001 is used to control the valve of the oil pipeline. Through its accurate control, the flow rate of the oil in the pipeline can be precisely adjusted, which not only improves the production efficiency but also reduces energy consumption. At the same time, its intelligent diagnosis function can timely detect the leakage and other faults of the valve, ensuring the safe operation of the pipeline.
Comparison with Competing Products
Compared with similar products, the V18345 – 1020120001 has more advanced automatic commissioning functions, which can save a lot of commissioning time. Its intelligent diagnosis function is also more powerful, which can provide more detailed fault information, helping users better maintain and manage the system. In addition, it has better compatibility and can adapt to a variety of different actuator models and communication protocols, providing users with more choices.
Selection Recommendations
- Compatibility: When selecting, it is necessary to ensure that the selected model is compatible with the existing valve actuator and control system to avoid compatibility problems.
- Installation environment: Consider the installation environment of the product, such as temperature, humidity, and vibration. Choose a model suitable for the installation environment to ensure the normal operation of the product.
- Budget: According to the actual budget, choose a product with appropriate performance and price. Although the price of high – performance products is relatively high, they can bring better control effects and reliability.
Precautions
- Installation: During installation, follow the installation instructions to ensure correct installation and connection to avoid leakage and other problems. Pay attention to the installation position to ensure that the positioner can work properly and is convenient for maintenance and operation.
- Power supply: Ensure that the power supply voltage is stable and within the specified range to avoid damage to the device caused by voltage fluctuations.
- Maintenance: Regularly check the operating status of the positioner, clean the dust and dirt on the surface, and check whether the connection is loose. According to the usage situation, timely replace the wearing parts to ensure the normal operation of the device.
