SIEMENS 6DR5020-0EG00-0AA0 SIPART PS2 Electropneumatic Valve Positioner

Overview

The SIEMENS 6DR5020-0EG00-0AA0 is a SIPART PS2 smart electropneumatic valve positioner for linear and part-turn pneumatic actuators. The SIEMENS 6DR5020-0EG00-0AA0 receives 4-20mA control signal from DCS or PLC and adjusts air output to drive the valve to the target opening position. It adopts non-contact NCS position sensing to reduce mechanical wear and supports intrinsic safety certification for hazardous process areas. The SIEMENS 6DR5020-0EG00-0AA0 is widely used as spare replacement for control valves in chemical, oil and gas, power and water treatment plants.

Features

The SIEMENS 6DR5020-0EG00-0AA0 supports double-acting pneumatic output and polycarbonate housing for stable field operation. It provides automatic initialization and self-tuning function to adapt to different actuator stroke and friction characteristics. The SIEMENS 6DR5020-0EG00-0AA0 includes built-in diagnostic functions such as supply air pressure monitoring, valve stick detection and travel deviation alarm. It carries Ex ia IIC T5 intrinsic safety approval for explosive environments. The SIEMENS 6DR5020-0EG00-0AA0 uses G1/4 pneumatic port and M20×1.5 electrical cable entry, matching standard valve mounting bracket for direct installation.

Specs

Device Type: Electropneumatic valve positioner Model: SIEMENS 6DR5020-0EG00-0AA0 Input Signal: 4-20mA Actuator Type: Double acting Housing: Polycarbonate Position Detection: Non-contact NCS sensor Pneumatic Connection: G1/4 Electrical Entry: M20×1.5 Protection Grade: IP66 Certification: Ex ia IIC T5 intrinsic safety Application: Control valve positioning, process flow regulation, industrial process loop

Principle

The SIEMENS 6DR5020-0EG00-0AA0 compares the 4-20mA setpoint signal with the actual valve travel measured by the internal NCS sensor. The internal I/P converter adjusts pneumatic output pressure to the actuator until the valve position matches the command value. The positioner continuously monitors air supply and valve movement. If supply failure or abnormal travel deviation occurs, the SIEMENS 6DR5020-0EG00-0AA0 triggers fault indication and drives the valve to safe position according to fail-safe setting.

Applications

The SIEMENS 6DR5020-0EG00-0AA0 is used for flow, pressure and temperature regulation control valves in chemical and petrochemical process plants. It serves boiler, heat exchanger and pipeline control loops in power generation systems. The SIEMENS 6DR5020-0EG00-0AA0 applies to spare stock and on-site calibration replacement of SIPART PS2 valve positioners. It also supports new valve assembly and hazardous area instrumentation retrofit projects.
