Hangyuan Pneumatics Breaks Through Another Technical Barrier! The Copper-Zinc Content of the Pneumatic Filter Pressure Reducing Valve Sets a New Industry Standard!!!

In industrial sectors with stringent requirements for gas purity, the presence of metallic impurities such as copper and zinc has always been a critical bottleneck that limits equipment performance and product quality. Now, Hangyuan Pneumatics is breaking through industry bottlenecks with technological innovation—its newly launched 25A series pneumatic filter-regulator valves reduce the copper and zinc content to below 0.5%, far exceeding mainstream standards and setting a new benchmark for the purity of pneumatic component materials.

Why are copper and zinc levels the “lifeline” of pneumatic equipment?
As the “air-source guardian” of a system, the 25A series pneumatic filter and pressure-reducing valve not only filters impurities and stabilizes pressure but also—crucially—its own material purity directly affects the safety of downstream equipment and the quality of end products. In high-end manufacturing sectors such as lithium batteries and semiconductors, copper and zinc ions can easily cause media contamination or equipment corrosion: in lithium-battery production, excessive copper and zinc levels may lead to degradation of cell performance and even pose a risk of short circuits; in precision electronics manufacturing, metallic impurities can directly impact product yield.
Previously, mainstream industry standards typically kept the copper-zinc content below 2%, with some high-end products reaching as low as 1%. However, Hangyuan Pneumatics has achieved a groundbreaking breakthrough of less than 0.5% by innovating its material formulations and upgrading its precision manufacturing processes, representing an improvement in purity of over 60% compared to conventional products.

Hangyuan Pneumatics’ breakthrough in purity is no accident—it’s the result of synergistic innovation based on three core technologies:
1. Customized substrate development: Abandoning the traditional brass substrate and adopting a composite formulation of high-purity aluminum alloy and special stainless steel to reduce the proportion of copper and zinc elements from the source.
2. Precision Forming Process: Utilizing an integrated cold forging technology to minimize material mixing contamination, with key component machining accuracy controlled within the 0.001 mm level.
3. Triple Testing System: Each product undergoes X-ray fluorescence spectroscopy testing, gas chromatography analysis, and simulated real-world operating condition testing to ensure that the copper and zinc content consistently meets the specified standards.

The low copper and zinc content does not come at the expense of performance. This filter-pressure-reducing valve simultaneously achieves three key advantages:
- Filtration accuracy up to 0.01 μm: Effectively traps tiny particulate impurities, making it suitable for high-precision applications such as pneumatic conveying of lithium battery raw materials.
- Pressure stabilization error: ±0.01 MPa—provides a continuous and stable air supply for the pneumatic system, reducing equipment operating energy consumption.
- Industry-wide compatibility: It not only meets the demands of high-end manufacturing sectors such as new energy and semiconductors, but also delivers outstanding performance in applications like laser cutting and laboratory gas control.
The launch of Hangyuan Pneumatics’ new product not only responds to the industry-wide requirement of “banning copper and zinc” in the lithium battery sector, but also leverages its technological prowess to drive the entire pneumatic components industry toward higher purity and improved performance.
From the laboratory to the production line, from technological breakthroughs to setting industry standards—Hangyuan Pneumatics has redefined the manufacturing philosophy of “details determine quality” with its breakthrough in achieving a purity level of 0.5%. Looking ahead, Hangyuan will continue to deepen its commitment to innovation in pneumatic technology, providing cleaner and more reliable air-source solutions for an even wider range of industries.
