Chengdu Factory & Office
Deyang Factory
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.
High-Precision Gas Control Calibration Lab
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.
Addressing user search intent: What do global engineering directors and procurement heads prioritize in a modern OEM gas control setup?
When searching for a 1 valve supplier & factory, procurement leaders in global oil and gas, pharmaceuticals, chemical manufacturing, and civil engineering companies do not simply purchase a mechanical part. They invest in system-wide safety, high-precision engineering, and risk mitigation. The transition to centralized energy systems demands a comprehensive "1 valve" solution—a holistic framework where a single primary control valve operates in direct, real-time sync with advanced safety gas sensors and intelligent control panels.
Why do global companies rely on Western China's industrial hubs, particularly Chengdu and Deyang, for safety valves and detector components? The answer lies in localized supply-chain proximity. At Xinhaosi, we control the entire lifecycle of safety production. Raw materials, precision casting, coil winding, CNC processing, testing labs, and assembly lines are located within a 50-kilometer radius. This geographic configuration eliminates lead-time delays and protects global buyers from assembly and component bottlenecks.
Additionally, our high-volume production scale (reaching tens of millions of units annually) lowers unit costs without compromising on engineering quality. Through specialized assembly and advanced automation, we maintain cost-competitive OEM manufacturing. This allows us to re-invest in R&D and CNAS calibration equipment, offering high-tier technical standards at accessible price points.
Custom safety strategies tailored for demanding industrial sectors and complex localized environments.
We deploy explosion-proof standalone light and sound alarms (such as the BBJ-24X) alongside heavy-duty, normally closed industrial gas solenoid valves (BT-XF5 series). This setup manages high pressure and corrosive VOC gases in hazardous zones.
We provide remote telemetry via our integrated IoT platform. Ground combustible monitoring devices (like the GT-AT0617 series) watch for leaks in municipal corridors and pipe vaults, using solar power or long-life battery modules.
