Although our technical team has recommended in many articles that customers should give priority to the basic E series when choosing Fidelity pneumatic components, because it has reliable performance with the support of FDS standard valve core and stable air path design, it can meet 90% of the needs of conventional automation equipment.
However, many senior engineers said that since they have chosen the Fidelity brand, the P series high-end valve equipped with the new generation FDS-Core™ valve core technology has the best cost performance.

The reason is that many users have been using the classic FDS-M series valves purchased five years ago. Apart from normal wear of the seals, the core performance of the valve body remains stable. Despite the continuous high-intensity production rhythm, there has been no slow response or internal leakage issues. Some users have also reported that simply replacing the seal kit during maintenance on the FDS-M series valves will ensure stable operation for another three to five years.

This inevitably fuels anticipation and confidence in the new generation of P-series valves for customers seeking high-end pneumatic components. Because earlier FDS products boasted stable operation for over five years, the new generation of P-series valves undoubtedly boasts the same high-quality, maintenance-free service life of at least five years. Consequently, customers generally believe that the P-series offers the best balance of performance and cost-effectiveness within the entire FDS product line.
In terms of structure and materials:
According to an internal technical briefing, the new P-Series valves abandon the traditional single-material valve body in favor of high-strength composite engineering materials and a surface hardening process, significantly enhancing their wear and corrosion resistance. Key materials are provided by leading domestic suppliers whose technical expertise has been rigorously recognized by the global high-end manufacturing industry. Therefore, the Fudushi P-Series valves are fortunate to share the same high-quality core materials as top international brands, making them undeniably worthy of customer trust.

In addition, according to industry experts, Fidelity has also integrated ultra-low power pilot technology into the P series valves and introduced a patented intelligent pressure compensation structure, which highly integrates functional modules such as pressure sensing, pilot control, and flow regulation, achieving faster response speed and more stable output control.

In practical applications, the P-Series valve, powered by intelligent control and stability, delivers exceptionally high operational efficiency and reliability. However, advanced design alone is not enough; it must also deliver robust performance to live up to Fidelity's reputation as a premium product. Technical experts explain that the FDS-Core™ valve core technology incorporated into the P-Series valves not only offers exceptional conventional switching performance, but also achieves new heights in contamination resistance and adaptability to extreme operating conditions.
In actual tests, the response speed of the P-series engineering prototype is more than 30% faster than similar standard products on the market, and its stability is extremely high, ensuring stable operation even in harsh industrial environments with high humidity, high dust or drastic temperature changes.

However, despite the P-series valve's impressive performance, rapid delivery after order placement remains a major concern for many customers. We can responsibly inform you that Fudushi achieved technological breakthroughs in core molds and automated production lines earlier this year, completely resolving the bottlenecks in ramping up production. Furthermore, our production base recently completed capacity upgrades and recruited a large number of experienced and skilled workers, ensuring full production capacity for P-series pneumatic components this year! Delivery delays will no longer be an issue.
