In the complex landscape of industrial automation, precise control of valves is of paramount importance. The Yamatake AVP100/102 Valve Positioner emerges as a highly reliable and intelligent solution, designed to meet the stringent demands of various industries. This valve positioner is part of the SVP3000 Alpha plus series, which is renowned for its advanced features and high - performance capabilities.
The Yamatake AVP100/102 is an electro - pneumatic valve positioner. Its primary function is to receive a control signal, typically a 4 - 20 mA DC signal from a control device such as a programmable logic controller (PLC) or a distributed control system (DCS). Based on this input signal, it accurately positions the valve to the desired opening or closing degree. This precise control is crucial for maintaining process stability, ensuring product quality, and optimizing the efficiency of industrial processes.
At its core, the AVP100/102 uses a microprocessor - based control system. The microprocessor continuously compares the received input signal with the actual valve position, which is detected by a position sensor (such as a potentiometer or a Hall - effect sensor). If there is a deviation between the set - point (input signal) and the actual position, the microprocessor calculates the necessary corrective action.
Features
It then sends control signals to an electro - pneumatic converter. The electro - pneumatic converter converts the electrical control signals from the microprocessor into pneumatic signals. These pneumatic signals are used to drive the valve actuator, either a pneumatic diaphragm actuator or a pneumatic piston actuator. The actuator then moves the valve stem, adjusting the valve's position until the actual position matches the set - point specified by the input signal.
One of the most significant features of the AVP100/102 is its auto - setup function. This is a fully - automatic configuration program that simplifies the installation and commissioning process. Unlike some other smart positioners in the market, the AVP100/102 does not require external devices such as a computer or a dedicated communicator for basic configuration. A simple press of an external switch is all it takes to initiate the auto - setup program.
Product Overview
During the auto - setup process, the positioner automatically identifies the type of actuator connected to it. It then proceeds to adjust the zero and span of the valve. This not only saves a significant amount of time during installation but also reduces the risk of human - error in configuration. In hazardous areas, this feature is particularly valuable as it allows for quick and safe valve adjustments without the need to bring in additional equipment that may pose a safety risk.
The positive seating function of the AVP100/102 enhances the reliability of the valve - control system. When the input signal to the positioner becomes lower than a previously set value, the positive seating function activates. It completely shuts off the valve by cutting off the unnecessary supply pressure to the actuator at a specific signal point. This ensures that the valve closes tightly, even in the presence of external disturbances such as pressure fluctuations in the process line.This feature is crucial in applications where a tight shut - off of the valve is required, such as in processes involving toxic or flammable substances. By maintaining the valve's full - shut - off capabilities continuously, the positive seating function helps prevent leaks and potential safety hazards, thereby contributing to a safer and more reliable industrial operation.The AVP100/102 is equipped with a powerful self - diagnostic function. This function allows the positioner to continuously monitor its own status and the status of the connected valve and actuator. At any given time, it can check for various faults such as sensor malfunctions, communication errors, or problems with the pneumatic system.In the event of a failure, the self - diagnostic function immediately alerts the operator. This can be in the form of an alarm signal sent to the control room or a visual indication on the positioner itself. By providing such quick and accurate fault diagnosis, the self - diagnostic function enables operators to take immediate corrective action. This not only minimizes downtime but also helps in predicting potential failures, allowing for proactive maintenance and reducing the overall cost of ownership.
