Our scale of operation and dedication to technology guarantees supply security and unmatched hardware reliability.
Adhering strictly to ISO9001 quality management system standards, Xinhaosi's core gas solenoid valves and detection instruments have obtained a full range of authoritative certifications. These include the China Compulsory Certification (CCC), explosion-proof accreditation, fire safety product certifications, CPA measurement instrument type approval certificates, and international approvals such as CE and SIL (Safety Integrity Level) certifications. Xinhaosi also holds key honors, including "National Quality Integrity Benchmark Enterprise" and "National Quality Leading Enterprise in the Gas Alarm Industry," and serves as the main drafting organization for the national standard of solenoid valves, cementing our 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 integrated flow monitoring functionality that combines 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.
Different industrial landscapes demand tailored mitigation techniques. Our systems bridge the gap between detection hardware and rapid shut-off actuation.
Hazardous, high-pressure environments require explosion-proof safety shut off valves (Ex d IIC T6) rated for Zone 1 and Zone 2 installations, coupled with continuous gas monitoring. Our solutions feature:
Safeguarding public utility grids demands real-time pressure management and valve control. Our smart network monitoring solutions incorporate:
Protecting commercial kitchens, high-rise buildings, and residential quarters from combustible gas buildup. Our household solutions provide:

Operating out of our advanced manufacturing centers in Chengdu and Deyang, Xinhaosi leverages the principles of Industry 4.0 to guarantee supply chain resilience. Our vertical integration strategy ensures that casting, precision machining, valve coil winding, assembly, and quality assurance are all managed under one single quality management system.
By automating key manufacturing steps, we achieve exceptional production tolerances and maintain high capacity for large-scale global orders. Our digitized inventory control tracks raw materials and components in real time, shielding our global clients from supply shocks. Our local procurement of premium alloys and seal materials, combined with efficient domestic transport networks, ensures reliable, on-time delivery of bulk safety shut off valve consignments.
Whether you require standard OEM replacements or complex custom ODM safety valves, our highly automated production lines can dynamically adapt to custom requirements without compromising delivery timelines. Our commitment to production efficiency enables competitive pricing without compromising quality control or material traceablity.
Adapting to the future energy landscape, our R&D is focused on next-generation gas control infrastructure.
As the global energy sector pivots toward green hydrogen (H2) blending, our materials science division is testing new seal elastomers and alloys to eliminate hydrogen embrittlement and micro-leakages.
Integrating microprocessors into our solenoid valve assemblies to continuously analyze current draw, stroke velocity, and mechanical friction, signaling predictive maintenance before field failures occur.
Developing dual-coil bistable solenoid mechanisms that only draw current during the millisecond transition state, minimizing power draw for remote solar-powered RTU sites.
