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.
Optimized safety shut-off configurations built to withstand critical, regional environmental demands.
In volatile, chemical-rich zones, our safety shut-off systems act as the primary defense. Engineered with heavy explosion-proof casings and ATEX compliance, they execute emergency shutdowns in milliseconds to mitigate high-pressure leaks.
Fully integrated household gas leak detection nodes connect directly with smart shut-off solenoid valves. In the event of a micro-leak, the valve cuts gas delivery at the main entry point to avert domestic fire hazards.
Designed for underground gas networks and pressure-regulating stations. The smart integration with SCADA networks allows municipal controllers to shut off zones remotely, preventing cross-district pipeline failures.
Unifying regional proximity, vertical manufacturing, and high capacity to secure reliable delivery times globally.
By utilizing two major operations hubs—our Chengdu Headquarters & R&D Center and the massive Deyang Advanced Manufacturing Plant—we guarantee zero-downtime redundancy. If logistics or supply flows in one corridor shift, operations load balances to the alternate site seamlessly, preserving contract schedules.
From component casting, PCB assembly, and sensor element calibration to final functional compliance checks inside our CNAS-accredited laboratory, we control 90%+ of our manufacturing supply chain. This minimizes exposure to volatile component shortages and ensures uniform quality control standards across all batches.
Advancing gas safety architectures through IoT, Edge AI Diagnostics, and Ultra-Low Latency Valve Shut Off Systems.
Development and implementation of wireless protocols (LoRaWAN, NB-IoT) directly into solenoid safety valves, allowing for real-time monitoring and trigger responses in remote and hard-to-access locations.
Integrating micro-controllers running predictive intelligence directly on valve boards. By analyzing pressure changes and coil heat profiles, the valves identify failure vectors before they occur.
Developing valves using advanced magnetic retention technology that consume zero power during open status and actuate instantaneously on electrical pulse termination for maximum fail-safe protection.

Key technical explanations concerning gas valve mechanisms and integration parameters.
Standard solenoid valves operate under continuous current, meaning any electrical surge, sag, or physical system crash can cause immediate operational failures. Our safety shut-off systems utilize advanced magnetic-latch or spring-loaded mechanical designs. Once triggered by a safety sensor, they shut in milliseconds and lock automatically. They can only be manually or remotely reset after clearing the hazardous event, preventing accidental reopenings during emergency conditions.
CNAS (China National Accreditation Service) functions under the ILAC-MRA framework, meaning tests executed inside our laboratory carry international equivalence. When you purchase high-precision gas detectors or safety control valves from Xinhaosi, the calibration data sheets are officially recognized in over 100 countries. This simplifies safety certification processes and helps prevent delays during local customs and regulatory inspections.
Yes, our industrial gas detectors and solenoid valves are constructed with heavy-duty cast aluminum alloys or stainless steel housings, treated with corrosion-resistant coatings. They are certified Ex d IIC T6 for explosive gas environments and exhibit IP66/IP67 ingress ratings. This allows them to function reliably in harsh offshore drilling rigs, wastewater treatment plants, and fertilizer manufacturing complexes.
Our industrial-grade solenoid shut-off valves actuate in under 1 second (typically <300 milliseconds) upon receiving an electrical trigger from the centralized controller. This rapid speed is critical for containing high-pressure lines and stopping gas flow before concentration levels reach the Lower Explosive Limit (LEL).
