Jewellok launches ultra-high-purity diaphragm valve series for chip and solar gas systems

By AI, Created 5:28 PM UTC, May 18, 2026, /AGP/ – Shenzhen Jewellok Technology unveiled a new ultra-high-purity diaphragm valve line on May 12, 2026, aimed at semiconductor, photovoltaic and biopharmaceutical gas delivery systems. The series is designed to cut contamination risk, improve leak integrity and support high-cycle operation in sensitive manufacturing environments.

Why it matters: - The new valve series targets processes where tiny contamination can reduce yield in semiconductor and solar manufacturing. - The product is built for corrosive, toxic and pyrophoric gases used in specialty gas delivery systems. - Jewellok positions the launch as a contamination-control upgrade for high-purity fluid handling.

What happened: - Shenzhen Jewellok Technology Co., Ltd. announced the official release of its Ultra High Purity Diaphragm Valve series on May 12, 2026. - The launch is aimed at semiconductor, photovoltaic and biopharmaceutical sectors. - The company says the valves are designed for gas delivery and fluid control systems.

The details: - Each valve body uses 316L VIM-VAR stainless steel. - The internal wetted surfaces are electropolished to a mirror-like finish with Ra of 5 micro-inches or less. - The series is built to exceed 6N, or 99.9999%, purity standards. - The diaphragm uses a metal-to-metal seal instead of soft elastomers. - Each unit is helium mass spectrometer leak tested to less than 1x10⁻⁹ atm·cc/sec. - Jewellok says the design supports rapid purging and reduces particle entrapment during gas changeovers. - The valves are rated for more than 100,000 cycles. - The series comes in manual and pneumatic versions. - The valves are designed to integrate with Valve Manifold Boxes and Gas Cabinets.

Between the lines: - The product launch reflects growing pressure on component makers to improve leak integrity as chip nodes shrink and solar production efficiency rises. - Zero-dead-volume design and high-cycle durability are central selling points because both affect uptime and process stability. - The focus on hermetic sealing suggests the company is targeting facilities where operator safety and system purity are equally important.

What’s next: - The new valve series is now available as part of Jewellok’s high-purity gas delivery lineup. - The company is likely to market the valves to manufacturers looking to tighten contamination control and extend equipment life. - Jewellok’s broader business remains centered on gas delivery equipment, including regulators, changeover manifolds and gas cabinets.

The bottom line: - Jewellok is betting that extreme purity, low leak rates and long cycle life will help its new diaphragm valves stand out in semiconductor and solar manufacturing.
