Jewellok Technology Unveils Next-Generation Ultra High Purity Diaphragm Valve for Critical Semiconductor and Solar Fabrication

SHENZHEN, China – Shenzhen Jewellok Technology Co., Ltd., a premier developer of high-precision gas and chemical delivery infrastructure, today announced the launch of its advanced Ultra High Purity Diaphragm Valve series. Engineered to meet the strict demands of sub-7nm semiconductor fabrication and high-efficiency photovoltaic manufacturing, these valves provide the uncompromising contamination control required for next-generation technology lines.

As microchip geometries shrink and solar cells move toward high-efficiency TOPCon and Heterojunction architectures, the demand for fluid system cleanliness has escalated. The new Jewellok Ultra High Purity Diaphragm Valve addresses these rigorous industry demands by offering a zero-dead-volume design that manages toxic, corrosive, and pyrophoric specialty gases without compromising purity.

Advanced Material Science and Surface Integrity
The cornerstone of the new series is its premium metallurgical construction. Every valve body is forged from high-grade 316L VIM-VAR stainless steel, a double-vacuum-melted material that minimizes non-metallic inclusions. To eliminate microscopic areas where moisture or particles can collect, the internal wetted surfaces are electropolished to a mirror-like roughness average (Ra) of 5 micro-inches or less. This optimized topology drastically accelerates system purging cycles and prevents outgassing during gas transitions.

Hermetic Sealing for Ultimate Safety
The Jewellok Ultra High Purity Diaphragm Valve utilizes a high-strength metal-to-metal diaphragm seal instead of soft elastomeric components that degrade over time. Each valve is tested using a helium mass spectrometer to ensure an exceptional leak integrity rate of less than 1×10⁻⁹ atm·cc/sec. This hermetic boundary guarantees that atmospheric oxygen and moisture cannot infiltrate the process stream, protecting both wafer yield and facility operators.

“Our mission is to engineer the silent gatekeepers of high-tech production lines,” said by James Yuan at Jewellok Technology. “By combining precision flow control with high-cycle durability, this valve series helps fabs minimize downtime and maximize productivity in their most sensitive chemical vapor deposition and atomic layer deposition processes.”

Long Service Life and Integration
Built for high-frequency operations, the valve series is rated to exceed 100,000 cycles under maximum operational pressure. The units are available in both manual and pneumatic actuation types, featuring standard 1/4-inch and 1/2-inch VCR face-seal connections. This ensures effortless integration into automated Gas Cabinets (GC) and Valve Manifold Boxes (VMB).
