Integrated Gas Delivery Solutions with VMB Valve Manifold Box and Automatic Gas Switchover Systems for Industrial

Integrated Gas Delivery Solutions combine the precision of a Valve Manifold Box (VMB) with the reliability of Automatic Gas Switchover Systems to create a seamless, uninterrupted flow of ultra-high purity (UHP) gases. This integrated approach is essential for industrial applications where process downtime can result in significant financial loss, such as in semiconductor fabrication, photovoltaic manufacturing, and continuous chemical processing.

The system begins with the Automatic Gas Switchover, which monitors cylinder or bulk source pressures. When a primary source reaches a pre-set low level, the system automatically transitions to a standby source without dropping line pressure or contaminating the stream. This ensures that downstream tools receive a constant supply of gas 24/7. Once switched, the gas is routed through the VMB, where it is branched into multiple, independently regulated “gas sticks.”

Constructed from electropolished 316L stainless steel, both the switchover and the VMB maintain strict UHP standards to prevent particle entrapment. The integration of PLC-controlled automation allows for remote monitoring of the entire supply chain, from the gas cabinet to the final process tool. By pairing automated supply redundancy with precise point-of-use distribution, these integrated solutions provide the safety, purity, and operational efficiency required for modern high-tech industrial infrastructure.

Shenzhen Jewellok Technology Co., Ltd. is a premier high-tech manufacturer specializing in the design and production of Ultra-High Purity (UHP) gas and chemical delivery systems. Based in the global innovation hub of Shenzhen, China, the company provides mission-critical fluid control solutions for industries where precision, safety, and absolute purity are non-negotiable.
Our core expertise lies in developing end-to-end infrastructure for semiconductor fabrication, photovoltaic (solar) manufacturing, EV battery production, and high-end laboratories. Jewellok’s product portfolio includes advanced Valve Manifold Boxes (VMB), Valve Manifold Panels (VMP), fully automatic gas cabinets (GC), and high-purity pressure regulators. Each system is engineered to handle specialty gases—including toxic, corrosive, and flammable materials—with zero contamination and maximum operational safety.

At the heart of our manufacturing process is a commitment to material excellence. We utilize electropolished 316L stainless steel to ensure internal surface finishes reach Ra ≤ 5 μin, effectively eliminating particle entrapment. Our systems feature helium leak rates as low as 1 × 10⁻⁹ atm·cc/sec, providing the airtight reliability required for sub-micron semiconductor processing.

Jewellok distinguishes itself through technical innovation and modular design. Our systems are equipped with Siemens or Allen-Bradley PLC controllers, offering 24/7 monitoring, automated emergency shut-off (ESO) protocols, and seamless integration into factory-wide management software. This allows our global clients to scale their production capacity efficiently while maintaining the highest safety standards.

Guided by the principles of “Quality First and Technological Innovation,” Shenzhen Jewellok Technology continues to push the boundaries of fluid dynamics. Whether providing components for a research lab or a large-scale wafer fab, we deliver the precision and reliability needed to power the next generation of global technology.
