Product Description

Product Description

Product Overview of KOSO EPA800-L10 Valve Positioner

The KOSO EPA800-L10 Valve Positioner is a state-of-the-art electro-pneumatic device designed to enhance the precision, reliability, and efficiency of valve control in industrial automation systems. Engineered for seamless integration with both linear and rotary valves, this positioner ensures accurate valve positioning by translating input signals from control systems into corresponding pneumatic outputs. Built to withstand harsh industrial environments, the EPA800-L10 is widely utilized in industries such as oil and gas, petrochemicals, power generation, and water treatment. Its robust construction, combined with advanced diagnostics and communication capabilities, makes it a critical component for optimizing process control, minimizing downtime, and improving operational safety. The device supports industry-standard communication protocols, including HART and Foundation Fieldbus, enabling real-time data exchange and integration into modern smart factory ecosystems.

Technical Features and Design Excellence

The EPA800-L10 stands out for its high-performance design, incorporating cutting-edge technology to deliver unmatched accuracy and durability. It operates on a force-balance principle, utilizing a microprocessor-based control system to precisely align valve positions with 4–20 mA analog or digital input signals. The positioner's rugged housing, constructed from corrosion-resistant materials such as aluminum and stainless steel, ensures long-term reliability in extreme temperatures (-40°C to +85°C) and hazardous conditions. It boasts an IP66/67 ingress protection rating, making it resistant to dust, moisture, and chemical exposure. Additionally, the device features an intuitive local interface with a rotary switch and LED indicators for easy configuration and diagnostics. Advanced self-calibration algorithms automatically compensate for mechanical wear, while built-in diagnostic tools monitor valve performance, detect anomalies, and alert users to potential failures, enabling predictive maintenance. The EPA800-L10 also supports dual air supply options and failsafe modes, ensuring continuous operation even during power or air supply disruptions.

Applications and Industry Benefits

The versatility of the KOSO EPA800-L10 makes it indispensable across a broad spectrum of applications. In the oil and gas sector, it ensures precise control of choke valves and emergency shutdown systems, enhancing safety and efficiency in upstream and downstream operations. Petrochemical plants leverage its accuracy to manage flow control in reactors, distillation columns, and pipelines, where process stability is critical. In power generation, the positioner optimizes steam and coolant valve control, improving turbine efficiency and reducing energy waste. Water treatment facilities rely on its durability to regulate flow in corrosive and high-pressure environments. By minimizing response time and hysteresis, the EPA800-L10 enhances process repeatability, reduces leakage risks, and extends valve service life. Its modular design simplifies installation and maintenance, while compliance with international standards such as SIL 2 and ATEX/IECEx certifications ensures compatibility with global safety regulations. Ultimately, the EPA800-L10 empowers industries to achieve higher productivity, lower operational costs, and sustainable performance in an increasingly automated world.
