Explore our industrial-grade OEM/ODM safety products engineered for high accuracy and extreme reliability
Founded in 2003, Xinhaosi has spent over two decades building one of the most trusted and influential brands in the global gas safety and automatic valve sectors. By integrating cutting-edge research and development, smart automated production lines, and strict quality control processes, we design safety systems that exceed typical operating benchmarks.
Our comprehensive production infrastructure spans industrial and residential gas detection systems, emergency shut-off gas solenoid valves (such as the high-pressure 1 Safety Valve systems), and smart urban pipeline networks. Backed by a dedicated international technical services team and CNAS-Accredited laboratory calibration, we deliver high-performance safety barriers to industries worldwide.
From petrochemical processing and hydrogen energy systems to commercial kitchens and urban pipeline monitoring, Xinhaosi products perform under the most challenging pressures. We align every design with the core philosophy of "Making Gas Safety Accessible Everywhere."

How we ensure global market compliance and engineering superiority through certified testing
Operating under ISO/IEC 17025, our in-house testing center is accredited by the China National Accreditation Service (CNAS) and recognized internationally under the ILAC-MRA framework. We run real-world pressure testing, gas chromatography, and lifespan tests to ensure every 1 Safety Valve and sensor matches international safety levels.
We hold patents for advanced industrial safety tools, including our graphical gas monitoring system that enables predictive maintenance (reducing system downtime by 30%). We also patented flow-monitoring solenoid valves that integrate instant leak detection with automatic mechanical shut-off systems.
Xinhaosi safety valves and industrial monitors are certified to meet international criteria, holding SIL certification, CE marking, Ex d explosion-proof certification, CPA instrument type approvals, and ISO 9001 quality management system credentials.

How our industrial valves function in challenging regional infrastructure and processing plants
In thermal processing plants, steel factories, and glassworks, maintaining pressure limits on gas combustion manifolds is essential. Operating as a fast-acting shut-off control, the 1 Safety Valve (such as the BT-XF5 solenoid valve) shuts down gas lines within 1 second if the flame fails, high pressure is detected, or utility power is lost.
In municipal gas networks, safety valves protect high-pressure pipelines from sudden surges. Our valves are designed for regional regulating stations, featuring low pressure drop, high flow capacity, and reliable sealing over long operating lifespans.
Our explosion-proof safety valves and gas detectors are built for hazardous zone classifications (Ex d IIC T6). They manage VOCs, hydrocarbons, and toxic process gases in refineries and storage depots, operating safely in environments with high vibration and electrical noise.
How Xinhaosi develops gas safety valves and control equipment for modern industrial applications
Xinhaosi established in Chengdu. Focused on early gas leak alarms and basic fire safety hardware. Built our initial research teams and manufacturing setups.
Launched specialized production lines for gas safety valves. Scaled up OEM manufacturing services and opened our Longtan Industrial Park office space.
Passed 10 million units in gas detector sales. Moved manufacturing into our main Chengdu facility and rolled out national sales and customer service networks.
Developed our cloud-based IoT gas safety monitoring platform. Gained official supplier status with major energy providers and received High-Tech Enterprise certification.
Began construction of the Deyang manufacturing facility. Set up our Petrochemical & International Business divisions and received Sichuan Technology Center recognition.
Completed the Deyang plant. Introduced wireless safety detectors and AI-enabled shut-off valves featuring real-time diagnostic checks, flow tracking, and predictive wear analysis.
How our Chengdu and Deyang industrial bases ensure stable global delivery and cost management
We manage core production in-house, from die-casting raw valve bodies and winding coils to testing electronic boards and final calibration. This vertical structure protects our supply chain from market bottlenecks and ensures consistent component standards.
Operating plants in both Chengdu and Deyang provides production redundancy. If one facility experiences maintenance down-time or regional disruptions, the other can take over manufacturing runs, preventing shipping delays for international projects.
Located near major western logistics and rail links (like the Chengdu-Europe express rail line), we ship directly to partners across Asia, Europe, and the Americas. Custom clearing processes and verified packaging avoid transport delays.
How we help international engineers customize, calibrate, and install our safety valves
We adapt safety designs to match regional requirements. Whether your project needs custom flange drillings (ANSI, DIN, or JIS), unique coil voltages, or housings built for corrosive industrial gases, our R&D team can modify configurations to fit.
Every custom safety valve undergoes pressure-drop modeling and finite element analysis (FEA) to confirm its structural integrity before production begins. We also supply custom private-label tags, product packaging, and localized documentation to make global distribution straightforward.
Additionally, our field-engineering team supports commissioning with remote technical guides, loop calculations, and calibration services, ensuring easy integration with your plant control networks.
