Founded in 2003, Xinhaosi is one of the most influential and trusted brands in the global gas safety industry. Over the past two decades, we have steadily built a robust and comprehensive production and service system, which integrates cutting-edge R&D, intelligent manufacturing with advanced automation equipment, digital marketing across global channels, professional after-sales support with an experienced technician team, flexible OEM/ODM services, as well as CNAS-Accredited laboratory calibration services that meet international standards.
Our diversified product portfolio covers industrial & residential gas detection & alarm systems, industrial & household gas solenoid valves, and urban gas pipeline network monitoring systems—all engineered to adapt to complex working environments and strict safety requirements. We produce and sell tens of millions of units annually, catering to a wide range of industries that demand reliable gas detection solutions, including oil & gas exploration and production, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, new energy, steel production, and beverage processing.
Guided by the core mission of “Making Gas Safety Accessible Everywhere,” we consistently deliver high-performance, reliable products and customized solutions tailored to each client’s unique needs. Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications, including national compulsory Products Certification, explosion-proof certification, fire product certification, CPA measurement instrument type approval certificate, and international approvals as CE, SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise" , "National Quality Leading Enterprise in the Gas Alarm Industry," member of the China Fire Protection Association, and the main drafting organization for the national standard of solenoid valves, further confirming its industry influence and reputation.
In the field of intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. These patents cover core technological areas, including a graphical monitoring system for gas detection and alarm, which enables predictive maintenance based on historical data to reduce equipment failure rates by over 30%, and a solenoid valve with flow monitoring functionality that integrates flow detection and alarm capabilities. The company also pioneered China's first networked bus-type gas leakage monitoring system and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security, demonstrating its leading position in cutting-edge technological research.
Our in-house laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. It operates in accordance with ISO/IEC 17025, the international standard for testing and calibration laboratories. It provides reliable and traceable testing services for gas detection and alarm products, solenoid valves, and related safety equipment. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities, certification bodies, and customers in China and overseas, helping to ensure product quality, safety compliance, and market access.
In modern gas infrastructure and industrial production, the half-inch shut-off valve is one of the most critical safety links. From global petrochemical hubs to urban residential gas distributions, the requirements for gas shut-off valves have transitioned from simple manual operation to integrated automation, fast shut-off capabilities, and extreme environmental resilience. Purchasing managers, project designers, and EHS (Environmental Health and Safety) specialists demand products that guarantee zero-leakage, low power consumption, and direct integration with IoT-enabled safety frameworks.
As governments worldwide enforce stricter municipal security and carbon-neutral policies, natural gas and hydrogen-blended utility systems are under close regulatory inspection. In this environment, a standalone shut-off valve is insufficient. Companies require comprehensive, ecosystem-level solutions that combine hardware reliability with software-based predictive analysis.
Xinhaosi's smart pipeline solutions combine physical shut-off capabilities with intelligent sensors. For example, our GT-AT0637 Wireless Smart Pressure Monitor works alongside our 1/2 Inch Solenoid Automatic Shut-off Valves to establish a self-contained monitoring and control loop. If pressure levels drop below or exceed predefined thresholds, the system triggers the shut-off valve within milliseconds, preventing gas leakage downstream. This system is monitored via a cloud-based IoT platform, allowing utilities to view real-time pipeline pressure metrics on web dashboards, reducing manual inspect costs and pipeline failure rates by over 30%.
The development roadmap of gas safety control technology at Xinhaosi focuses on three core areas: Intelligence, Energy Efficiency, and Multi-Gas Compatibility.
From petrochemical refineries in the Middle East to municipal heating systems in Europe, half-inch shut-off valves are used in millions of installations daily. The industrial sector requires valves that can handle high flow velocities and resist chemical exposure, while the residential sector prioritizes compact designs, aesthetic integration, and ease of installation. Xinhaosi’s manufacturing facility accommodates both needs, utilizing automated assembly and testing lines that ensure dimensional accuracy and consistent sealing across high-volume production runs.
Over two decades of continuous innovation and expansion, building global gas safety leadership.
Operating a global supply chain requires adherence to varying regional safety laws and certification standards. Xinhaosi helps international buyers navigate these requirements by offering full regulatory compliance assistance. From safety standards like EN 50291 in Europe and UL 1484 in North America to specific fire protection certificates in Asia, our engineering and R&D teams ensure all products meet the necessary local guidelines before shipment.
Our CNAS-accredited calibration laboratory (operating under ISO/IEC 17025) ensures that every half-inch shut-off valve and matched gas detector undergoes trace-calibrated inspection prior to dispatch. We provide complete test records for chemical exposure, high-pressure sealing, explosion resistance, and vibration endurance. If a project requires custom validation, our engineers can adjust testing plans to match local requirements, ensuring smooth installation and regulatory approval.
