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 the complex demands of safety instrumentation and emergency valve shut-off systems across global sectors.
In upstream exploration, midstream pipelines, and downstream refineries, hydrocarbon leaks represent an existential risk. Our heavy-duty gas solenoid valves (such as the KT-XF5 industrial series) act as the final fail-safe barrier, linking seamlessly with SIL-2 flame and gas detection systems to trigger immediate shut-offs during high-pressure events.
Modern municipalities rely on complex underground gas networks. Xinhaosi provides intelligent monitoring platforms linked with low-power monitoring devices, enabling gas utilities to detect minor pressure changes or methane spikes in deep utility shafts, automatically shutting down the corresponding network sector using high-flow "Valve 2" class configurations.
Coking and smelting operations release dangerous carbon monoxide (CO) and combustible gases. Our multi-point monitoring equipment coupled with rapid-response, explosion-proof detector units guarantees plant-wide protection, preventing structural explosions and toxic poisoning in high-temperature environments.

Ensuring cross-border compliance through localized service branches and rigorous standard certification.
All solenoid valves and alarm systems destined for the European market are certified to meet European Standard EN 50291 (for residential gas detection) and EN 60079 (for explosive atmospheres). Our industrial safety shut-off systems carry the CE mark, asserting full conformity with Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) regulations.
For high-risk environments such as chemical plants and chemical storage terminals, our valve solutions are designed according to IEC 61508 standards. Undergoing exhaustive failure modes, effects, and diagnostic analyses (FMEDA), our valves achieve Safety Integrity Level 2 (SIL-2) as standalone devices and SIL-3 in redundant configurations.
Xinhaosi explosion-proof detectors and valve actuators undergo international testing to secure ATEX and IECEx compliance. These products are rated for Zone 1 and Zone 2 hazardous areas, utilizing flameproof "d" and encapsulated "m" protection techniques to ensure they cannot become ignition sources.
Equipped with state-of-the-art testing stations, our laboratory provides traceable calibration conforming to ISO/IEC 17025. We offer local calibration certificates recognized in over 100 countries through the International Laboratory Accreditation Cooperation (ILAC) mutual recognition agreement.
Tracing our journey from a localized pioneer to an international beacon of intelligent gas safety systems.
Leading the next generation of safe flow controls through data-driven predictive safety platforms.
Traditional solenoid valves are reactive, shutting down only when a gas leak has already occurred. Xinhaosi is developing the AI Valve 2 Series, combining integrated pressure, flow, and temperature sensors directly into the valve body. These valves communicate with smart algorithms to identify anomalies, such as micro-leaks, valve plug wear, or coil degradation, before an emergency arises.
Additionally, we are migrating our wireless systems to ultra-low-power protocol designs (such as LoRaWAN and NB-IoT). This enables reliable communication for gas detectors and emergency shutdown valves over kilometers in heavy industrial areas, without the need for expensive structural wiring.
Our commitment to sustainability also includes optimizing our manufacturing processes. The newly built Deyang Factory utilizes intelligent energy management systems and robotic assembly lines to minimize carbon footprints while raising QA tolerances to unprecedented levels.
Getting answers to the most common configuration and engineering questions from our system specialists.
Unlike standard regulatory control valves, emergency gas safety solenoid valves (like the XF2 or KT-XF5 series) are designed as "fail-safe" shut-off devices. They use a pre-loaded internal spring system. Under normal operations, the valve is kept open magnetically or via mechanical manual reset. When a gas sensor detects a leak, the controller interrupts power to the solenoid coil, instantly releasing the internal spring to shut the valve in less than one second. This system ensures positive closure even during total power failures.
CNAS accreditation means our calibration laboratory operates in strict compliance with the international standard ISO/IEC 17025. This ensures that every test gas mixture, optical spectrometer, and environmental test chamber we use is fully traceable to national and international metrology standards. Test certificates issued by a CNAS laboratory carry global recognition through the ILAC-MRA framework, making regulatory compliance checks straightforward for international projects.
Traditional analog gas monitoring requires running dedicated 4-20mA signal wires from every single detector back to the main control panel. A bus-type network system (such as M-Bus or RS485 daisy-chains) connects dozens of detectors to a single communication line. This layout reduces total cabling needs by up to 60%, simplifies diagnostics, and allows the control panel to receive advanced data, including sensor health, calibration status, and exact PPM readings.
Combustible gas leaks create an atmosphere that can ignite with the smallest electric spark or high surface temperature. Explosion-proof certification (such as ATEX, IECEx, or national Ex standards) guarantees that an electronic device is designed to prevent these occurrences. This is achieved by containing any internal explosion within a heavy-duty flameproof housing (Ex d), encapsulating electronics to prevent gas ingress (Ex m), or using intrinsically safe designs (Ex i) that limit energy below the threshold needed to ignite gas.
