MOORE 42-30 Smart Electro-Pneumatic Valve Positioner

The MOORE 42-30 is a smart electro-pneumatic valve positioner designed for precise control of pneumatic actuators. It converts a standard 4-20 mA control signal into a proportional pneumatic output, accurately positioning linear or rotary valves. With HART communication, IP65 protection, and a wide operating temperature range, the 42-30 is suitable for demanding process control applications in chemical plants, refineries, and power generation facilities.

High Precision and HART Communication

The 42-30 provides ±0.5% control accuracy and ±0.2% repeatability, ensuring precise valve positioning under varying process conditions. The HART communication protocol enables remote calibration, diagnostics, and access to real-time valve health data, including travel statistics and alarm information. This digital capability transforms the positioner from a simple actuator into a "smart" device that supports predictive maintenance strategies.

Rugged Design for Process Environments

The MOORE 42-30 is built to withstand extreme industrial environments. It operates reliably in ambient temperatures ranging from -40°C to +80°C, making it suitable for both outdoor installations in cold climates and high-temperature process areas. The IP65 (NEMA 4X) rated enclosure provides protection against dust, water jets, and corrosion, ensuring long-term performance in chemical, petrochemical, and offshore applications. The positioner mounts directly onto NAMUR-standard pneumatic actuators, simplifying installation and alignment.

Application Domains

The MOORE 42-30 is used in chemical and petrochemical processing for precise flow and pressure control, oil and gas refineries for valve automation in distillation columns, power generation for steam turbine bypass valves, pharmaceutical manufacturing for sterile process valves, and water treatment for automated control of large gate valves.
