The Siemens SIPART PS2 series of intelligent valve positioners, a cornerstone device in the industrial automation sector, has long served critical industries including chemicals, petrochemicals, power, steel, paper, and pharmaceuticals. With its modular design, flexible scalability, extensive diagnostic capabilities, and global sales exceeding 2.5 million units, the series has established itself as a benchmark in industrial valve control. However, as global industries increasingly demand green, low-carbon, and efficient production, the limitations of traditional valve positioners in material consumption, energy efficiency, and intelligence have become more apparent. Against this backdrop, Siemens launched a comprehensive upgrade of the SIPART PS2 in 2025, redefining performance standards for industrial valve positioners through eco-design principles and digital technology.

This upgrade focuses on three core objectives: green efficiency, safety, and operational excellence, addressing key technological challenges as follows:

Green Efficiency Upgrades

• Material Innovation: Reduced thermoplastic material usage lowers product weight by 3%, aligning with Siemens’ EcoTech eco-design standards. These standards, covering sustainable materials, optimized usage, value recovery, and recycling, have been independently verified by TÜV in accordance with ISO 14020/14021.
• Energy Revolution: Steady-state air consumption drops to 0.01 Nm³/h, a 70% reduction from previous models and 95% below market averages, significantly cutting operational costs and CO₂ emissions for users.

Enhanced Reliability

• Wear-Free Design: Extended sensor lifespan, improved vibration resistance, and expanded angular range (100° to 160°) broaden application scenarios.
• Ultra-Longevity: A mean time between failures (MTBF) of 359 years, coupled with modular design for easy maintenance and a global service center network, ensures rapid response times.

Intelligent Innovation

• Bluetooth Connectivity: A new Bluetooth interface enables remote monitoring of valve status, diagnostic report export, and one-click parameter copying via the SITRANS mobile IQ App, boosting commissioning efficiency by over 50%.

Siemens’ upgrade is not merely an iteration of product performance but a profound embodiment of the Industry 4.0 philosophy of “green smart manufacturing.”

• Eco-Closed Loop: The integration of EcoTech declarations and TÜV verification marks a standardized, transparent phase in lifecycle assessments of industrial equipment, setting a benchmark for green transformation in the sector.
• Digital Empowerment: Bluetooth connectivity and mobile app integration dismantle the “siloed” maintenance model of traditional valve positioners, driving industrial field devices toward intelligent terminals that are “perceptible, interconnected, and optimizable.”
• Market Leadership: With breakthroughs in materials, energy efficiency, reliability, and intelligence, the upgraded SIPART PS2 is poised to further solidify Siemens’ dominance in the high-end valve positioner market, offering global industrial users more sustainable and competitive solutions.

The comprehensive upgrade of Siemens’ SIPART PS2 represents a pivotal milestone in the green and intelligent transformation of industrial automation. Looking ahead, as the world advances toward carbon neutrality, Siemens is likely to continue leading the charge toward more efficient, environmentally friendly, and intelligent industrial equipment through technological innovation.
