The YVP110 Advanced Valve Positioner is a digital valve control device that controls valve pneumatic actuators in response to commands from a fieldbus control system. It communicates using the FOUNDATION fieldbus protocol.
The YVP110 is a versatile component that minimizes transmission lag, improves valve characteristics and response, and reduces flow-pressure variation effects.
The ValveNavi™ is a software tool that greatly facilitates the process of setting up, tuning, and maintaining the YVP110.

- Fieldbus technology introduced to realize predictive and preventive maintenance.
- ISAE to improve the reliability of diagnosis and parameter setting, utilizing data collected by PRM.
Progress in digital signal processing and network technologies has enabled advanced functions which cannot be achieved by traditional field devices with 4-20 mA signal, to be implemented on field devices. Standardization of international fieldbus specifications, notably the FOUNDATION™ Fieldbus, has enabled users to build optimum field networks comprised of freely chosen field devices from various device vendors.
Latest field devices have not only various self-diagnosis functions but also process-interface-diagnosis functions such as valve diagnosis of valve positioners and impulse line blockage detection of differential pressure transmitters. The YVP valve positioner can easily perform initial tuning, parameter adjustment, trend monitoring, and valve diagnosis, by using the ValveNavi YVP management software.
The environment surrounding the process plant industry has changed dramatically because of the recent economic changes, deregulation, and increasingly fierce competition among global companies. Users are strongly requesting instrumentation equipment vendors to reduce total cost throughout the life cycle and help improve the efficiency of plant operation.
