Industry Insight

As pillar industries of the national economy, coal chemical and petrochemical sectors frequently face severe operating conditions such as high-frequency on-off cycles, media erosion, and flammable/explosive environments. As the core component of fluid control, the reliability, wear resistance, and safety of intelligent control valves directly determine production efficiency and operational safety. SUPCON has launched the SN Series Pneumatic High-Frequency Ball Valve, featuring innovative structural design and core technological breakthroughs, and has obtained authoritative certifications, providing a reliable solution for high-frequency conditions in these two industries.

SN Series Features

▶ Ball and seat: A scraper-style structure quickly removes powder adhering to the ball surface, preventing material accumulation and action jamming.
▶ Spring cavity protection structure with dust-proof design prevents particulate media from entering the seat cavity and causing preloaded spring failure, ensuring smooth operation.
▶ Double-guided valve stem structure ensures stable valve switching action.
▶ Multiple sealing design of the packing box meets low-emission requirements while greatly enhancing wear resistance.

SN Series Core Competitiveness

The SN Series Pneumatic High-Frequency Ball Valve addresses the core pain points of high-frequency operation and complex media in coal chemical and petrochemical industries, offering five key advantages:

① Long service life suitable for high-frequency, wear-resistant conditions. Optimized structural design enables switching cycles exceeding 1,000,000 times. It has passed third-party testing by Zhejiang Pump and Valve Quality Inspection Center, with results meeting requirements and reaching the domestic leading level.
② Low-torque design combined with fire-safe and dust-proof structures, suitable for complex dust and high-temperature environments, eliminating safety hazards.
③ Packing meets ISO 15848 low-emission standard, complying with petrochemical industry safety and environmental control requirements.
④ High-frequency fast response adapted to process conditions:

l For diameters < DN150: switching speed ≤ 1.5 seconds

l For diameters ≥ DN150: switching speed ≤ 2.5 seconds

⑤ Meets API 598 leakage standard, ensuring sealing and stability of fluid control, avoiding production interruptions and safety risks caused by leakage.

The full SN Series Pneumatic High-Frequency Ball Valve has passed multiple domestic and international core certifications, including TUV SIL3 certification, API 607 fire-safe certification, API 6D certification, API 6FA fire-safe certification, ISO 15848 low-emission certification, and China Classification Society Type Approval. These comprehensively cover core indicators such as safety, sealing, and durability, making the valve suitable for high-risk, high-demand production processes like coal chemical and petrochemical refining.

SN Series Benchmark Implementations

The SN Series Pneumatic High-Frequency Ball Valve has been successfully applied in many leading industry enterprises, demonstrating excellent adaptability and stability in real-world conditions:

l Guizhou Wengfu Jiangshan Chemical Project: The adopted high-frequency fixed-type hard-seated ball valve achieves rapid on-off cycles of 1.5 seconds per cycle, adapting to high-frequency switching requirements in chemical reaction processes, with continuous trouble-free operation.

l Yulong Petrochemical Project: To overcome the "bottleneck" of imported valves, after on-site inspections and in-depth discussions, the project selected customized SN Series high-frequency ball valves, achieving stable on-off cycles of 2 seconds per cycle and effectively solving wear problems.

l SINOPEC New Materials Project: The ball valves operate stably at a high frequency of 2 cycles per minute. With fully protected spring sealing and double-layer packing design, they address media leakage and sealing wear pain points, achieving long-term stable operation.

Additionally, this series has been successfully applied to enterprises such as Chaoyang Jinda Titanium and PetroChina Daqing Refining & Chemical, covering various sub-segments of coal chemical and petrochemical industries, accumulating rich practical application experience.
