Siemens 6DR4004-8D SIPART PS2 Positioner Mounting Kit

The Siemens 6DR4004-8D is a universal stainless steel mounting kit designed for SIPART PS2 positioners. It complies with NAMUR IEC 60534-6-1 standards for linear actuators, providing a precise and vibration-resistant mechanical link for valve strokes ranging from 3 mm to 35 mm.

Product Overview

The Siemens 6DR4004-8D functions as a specialized universal mounting kit specifically engineered for the SIPART PS2 series of electropneumatic positioners. Primarily, this hardware set provides the mechanical interface required to install a positioner onto linear actuators according to the IEC 60534-6-1 (NAMUR) standard. Consequently, it serves as the critical physical link that ensures precise feedback between the valve stem and the positioner’s internal potentiometer. By utilizing a high-integrity stainless steel construction, the 6DR4004-8D delivers the structural stability necessary for accurate valve modulation in demanding industrial environments.

Technical Performance and Functional Features

  • Standardized NAMUR Compliance: In addition to its versatile design, the kit adheres strictly to the IEC 60534-6-1 standard for linear actuators. As a result, the hardware ensures a perfect geometric alignment between the positioner and the valve, which significantly reduces mechanical hysteresis.
  • Corrosion-Resistant Construction: Furthermore, the 6DR4004-8D utilizes high-grade stainless steel and galvanized components. This material choice protects the mounting assembly from chemical exposure and atmospheric oxidation. Thus, it effectively prevents mechanical binding in harsh outdoor or corrosive process areas.
  • Adjustable Feedback Mechanism: To accommodate various valve strokes, the kit includes an adjustable lever and pick-up bracket. Moreover, this flexibility allows the system to support a wide range of linear travels, typically from 3 mm to 35 mm. Consequently, it provides a universal solution for diverse valve types within a single plant.
  • Secure Vibration Resistance: Regarding operational stability, the mounting brackets feature reinforced joints and locking washers. Therefore, the hardware maintains its calibration even when installed on high-vibration control valves or in proximity to heavy rotating machinery.
  • Complete Installation Hardware: To simplify field maintenance, the kit includes all necessary bolts, nuts, and specialized U-brackets. Consequently, technicians can complete the installation using standard tools, which reduces the time required for positioner replacement or initial commissioning.

Operational Compatibility and Integration

System engineers seamlessly utilize the 6DR4004-8D to mount the SIPART PS2 (6DR5 series) positioners onto various globe and diaphragm valves. In addition to its mechanical reliability, the kit’s geometry is optimized for the standard feedback lever of the PS2, ensuring a linear relationship between the valve position and the electronic signal. Furthermore, because this mounting equipment meets Siemens’ rigorous quality benchmarks, it successfully satisfies the reliability demands of the chemical, oil and gas, and power generation sectors. Ultimately, these features combine to provide a durable and precise foundation for critical flow control loops.
