The Koso PPA800 Valve Positioner stands as a pinnacle of precision engineering in industrial automation, designed to deliver accurate and reliable control of pneumatic valves across diverse applications. As a cornerstone of Koso's advanced instrumentation portfolio, this smart positioner combines cutting-edge technology with robust construction to optimize valve performance, enhance process efficiency, and reduce operational costs. With its ability to adapt to various valve types and communication protocols, the PPA800 offers unparalleled flexibility for modern industrial environments.
The PPA800 employs advanced microprocessor technology to achieve exceptional positioning accuracy of ±0.5% or better. This precision ensures that valves respond accurately to control signals, minimizing process variability and improving product quality. The positioner's adaptive algorithms continuously adjust to changing conditions, maintaining optimal performance even in the presence of valve hysteresis, friction, or pressure fluctuations.
Designed for versatility, the PPA800 is compatible with a wide range of linear and rotary valves, including globe, butterfly, ball, and diaphragm valves. It supports both direct and reverse acting modes, making it suitable for diverse applications. The positioner can be easily configured for different valve sizes and types, reducing the need for multiple models and simplifying inventory management.
Features
Equipped with industry-standard communication protocols, the PPA800 enables seamless integration into modern automation systems. It supports HART®, FOUNDATION Fieldbus, and PROFIBUS PA, allowing for remote configuration, diagnostics, and monitoring. This digital connectivity enhances system visibility, simplifies maintenance, and enables predictive analytics for proactive asset management.
Built to withstand harsh industrial environments, the PPA800 features a robust aluminum housing with a corrosion-resistant finish. It meets IP66/68 ingress protection standards, ensuring reliable operation in dusty, wet, or corrosive conditions. The positioner is also designed to resist vibration and mechanical shock, making it suitable for use in demanding applications such as oil and gas, chemical processing, and power generation.

Product Overview
The PPA800 incorporates an intuitive user interface with a large, backlit LCD display and tactile buttons. The display provides clear visual feedback on valve position, status, and diagnostic information, while the menu-driven interface simplifies configuration and troubleshooting. Local operation is further enhanced by a manual override function, allowing for direct control during maintenance or emergencies.The PPA800 offers flexible configuration options to suit various application requirements. Configuration can be performed locally using the front panel buttons and display or remotely via digital communication protocols. The positioner supports automatic calibration routines, which simplify setup and reduce commissioning time. Key parameters such as stroke length, deadband, and response characteristics can be easily adjusted to optimize valve performance. Additionally, the PPA800 stores calibration data and configuration settings, ensuring consistent operation even after power cycling or maintenance.
The PPA800 features comprehensive diagnostic functions that enable proactive maintenance and reduce unplanned downtime. Built-in sensors monitor valve position, actuator pressure, and temperature, providing real-time data on valve performance. The positioner can detect anomalies such as valve sticking, excessive friction, or leaks, and generate alerts or alarms to notify operators. Advanced diagnostics also include predictive maintenance capabilities, which analyze trends and patterns to identify potential failures before they occur. This allows for scheduled maintenance and minimizes the risk of costly process interruptions.By improving process efficiency, reducing maintenance costs, and enhancing safety, the PPA800 delivers significant value to operators and helps ensure the smooth and reliable operation of industrial processes. Whether used in new installations or retrofitted into existing systems, the Koso PPA800 provides a cost-effective and future-proof solution for valve control and automation.
