Shenzhen Jewellok Technology Co., Ltd. is a high-tech manufacturer specializing in ultra-high purity (UHP) gas and chemical delivery systems, precision control valves, and pressure regulators. Headquartered in Longhua District, Shenzhen, China, Jewellok is dedicated to providing reliable, high-performance fluid control solutions for the most demanding industries worldwide.

Established with a strong engineering foundation, Jewellok focuses on the research, development, and manufacturing of UHP components that meet stringent purity, safety, and reliability standards. The company’s core product portfolio includes ultra-high purity diaphragm valves (manual, pneumatic, and air-actuated), single- and double-stage pressure regulators, fully automatic and semi-automatic gas cabinets (GC, VMB, BSGS), gas changeover manifolds, compression tube fittings, and complete custom gas delivery systems. All products are primarily constructed from 316L VIM-VAR stainless steel with advanced electropolishing (Ra ≤ 5 µin) to ensure minimal particle generation and superior leak integrity.

Jewellok serves critical sectors including semiconductor manufacturing, microelectronics, photovoltaics, biotechnology, pharmaceuticals, laboratories, aerospace, hydrogen energy, and fine chemicals. Its solutions support key processes such as CVD, etching, and high-purity gas distribution, helping customers maintain process stability, maximize yield, and ensure operational safety in cleanroom environments.

Committed to innovation and customer-centric solutions, Jewellok offers extensive customization services, including CAD/3D prototyping, OEM/ODM branding, and full system design. The company maintains flexible production with no minimum order quantity for many standard items and emphasizes rapid delivery. Its products are engineered for extreme conditions — handling corrosive, toxic, flammable, and specialty gases with precision pressure control and automated features such as PLC-controlled touch-screen interfaces for automatic purging and switchover.

Guided by the principles of "Purity, Precision, and Performance," Jewellok continues to invest in advanced manufacturing technologies and quality control to exceed industry standards (including SEMI compatibility). As a trusted partner to global fabs, research institutes, and high-tech manufacturers, the company delivers cost-effective yet high-specification solutions that support the advancement of next-generation technologies.

With a growing international presence and a strong domestic manufacturing base in Shenzhen, Shenzhen Jewellok Technology Co., Ltd. is positioned as an agile and innovative supplier in the global UHP gas delivery market.
