700 Series Smart Valve Positioner
●The Smart Valve Positioner 700 Series (model number: AVP7**) not only inherits the reliability of the core technology established by the 300 Series but has advanced control valve diagnostic techniques and the latest system integration technology.
●The Smart Valve Positioner 700 Series provides numerous benefits for various stages in the life cycle of users’ plants and contributes to the improvement of plant productivity.
■FIVE FEATURES:
●POINT1 Excellent environmental resistance and robustness
◆Azbil’s unique isolating structure separates the electrical/electronic parts, air circuits, and terminal box from each other, achieving high environment resistance. In addition, the improved travel sensor provides better vibration resistance. These features provide what is most important for field equipment: long-term high reliability.
●POINT 2 Comprehensive control valve diagnosis
◆With newly added pressure sensors in the positioner, it is possible to measure the supply air pressure, nozzle back pressure, and output air pressure. The control valve diagnostic algorithms, which determines the soundness of the control valve based on the measured values of those pressures, have been enhanced.
◆The measured pressures are used for both offline commands in which the soundness of the control valve is determined based on its response to commands sent from the host device when the plant is shut down, and online diagnosis, in which the soundness of the control valve is determined based on the information collected during the operation of the plant. This supports the implementation of status-based maintenance and predictive maintenance.
●POINT 3 Do-from-anywhere adjustment and setup
◆The new adjustment/setting mechanism (local user interface LUI) is a combination of an LCD and push buttons mounted on the front of the positioner that allows users to operate the positioner without compromising the explosion-proof construction.
◆It is also possible to make adjustments and settings from various portable adjustment/setting tools and networked device management systems.
Because users can access the positioner from anywhere, including the worksite, maintenance shop, and control room, adjustment and settings configuration work before operation, and also troubleshooting, can be done more efficiently.
●POINT 4 Advanced system integration
◆The Smart Valve Positioner 700 Series supports the HART protocol, which is the de facto communication standard in the plant industry, and the latest version of Foundation - fieldbus. and has been certified by both organizations. Support for latest communication standards allows the host device to make the best use of information on control valve operating status and diagnostic results.
●POINT5 Improved energy efficiency and controllability
◆The basic performance of the Smart Valve Positioner 700 Series as a positioner has also been improved. Compared to our previous products, we have reduced the consumption of instrumentation equipment air during steady operation by 20%, helping to save energy in plant operation
◆Also, the newly developed double-acting pilot relay improves the operating speed of large control valves by 20% compared to our previous products.
