Product Description

Fisher Type 582i Electro-Pneumatic Valve Positioner – Product Description

The Fisher Type 582i Electro-Pneumatic Valve Positioner is a high-performance control solution designed to bridge the gap between electronic control systems and pneumatic valve actuators. Engineered by Emerson, a leader in industrial automation and process control, the Type 582i ensures precise valve positioning by converting electrical control signals (typically 4–20 mA DC) into proportional pneumatic output pressures. This advanced positioner is widely used in critical industries such as oil & gas, chemical processing, power generation, and water/wastewater treatment, where reliability, accuracy, and compliance with global safety standards are paramount.

Core Functionality and Precision Engineering
At its core, the Fisher Type 582i operates as an electro-pneumatic transducer, translating analog or digital control signals into precise air pressure outputs that drive valve actuators. This enables seamless integration with PLC, DCS, and SCADA systems, allowing operators to achieve granular control over process variables such as flow rate, pressure, and temperature. The positioner's output pressure ranges are customizable, typically spanning 3–15 psig (20–100 kPa) or 6–30 psig (40–200 kPa), depending on the application's requirements. With a control accuracy of ±0.5% of span (standard) and optional high-resolution models achieving ±0.1%, the Type 582i delivers exceptional repeatability and stability, minimizing process deviations and ensuring optimal operational efficiency.

Robust Design for Harsh Environments
Built to withstand the rigors of industrial environments, the Type 582i features a rugged aluminum alloy housing paired with stainless steel internal components, providing durability against vibration, corrosion, and extreme temperatures. It operates effectively within a wide temperature range of -40°C to +85°C (-40°F to +185°F), making it suitable for both indoor and outdoor installations, including offshore platforms and remote field operations. The positioner's IP65/NEMA 4-rated enclosure protects against dust ingress, water jets, and harsh weather conditions, ensuring long-term reliability in challenging settings.

Advanced Features for Process Optimization
The Type 582i is equipped with several advanced features to enhance performance and ease of use:

Digital Communication: Optional HART Protocol integration enables remote configuration, diagnostics, and real-time monitoring via compatible handheld communicators or control systems. This allows technicians to calibrate the positioner, detect faults, and analyze valve behavior without shutting down operations.
Self-Diagnostic Capabilities: Built-in diagnostics continuously monitor valve stroke, position feedback, and actuator health, alerting operators to issues such as air supply failure, mechanical binding, or sensor drift. This predictive maintenance capability reduces unplanned downtime and extends equipment lifespan.
Adjustable Calibration: Manual zero/span adjustments and auto-calibration via HART ensure the positioner adapts to evolving process conditions, maintaining accuracy over time.
High-Resolution Option: For applications demanding ultra-precise control, such as pharmaceutical manufacturing or semiconductor processing, the high-resolution variant minimizes hysteresis and deadband effects.
Safety and Global Compliance
Safety is a cornerstone of the Type 582i's design. It is certified for use in hazardous locations under major international standards:

ATEX and IECEx for explosive gas/vapor environments (Zone 0/1/2).
FM and CSA approvals for North American hazardous area compliance.
SIL 2/3-capable for integration into safety-instrumented systems (SIS). Additionally, the positioner meets NACE MR0175 standards for sour service applications in oil & gas, resisting sulfide stress cracking in hydrogen sulfide (H2S)-rich environments. Its supply air pressure requirements (20–40 psig for 3–15 psig output; 40–60 psig for 6–30 psig output) ensure compatibility with standard industrial air systems, while its lightweight design (approximately 2.3 kg or 5 lbs) simplifies installation on rotary or linear actuators, including Fisher's own V250, HP Series, and other OEM-compatible models.
