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 such as CE and 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.
Pioneering the next generation of smart gas containment through predictive analytics, edge computing, and ultra-reliable low-power actuation.
Integrating microprocessors and flow sensors inside the valve body allows real-time diagnostics. Valves can auto-detect internal mechanical drag, seal deterioration, and micro-leaks before they manifest as critical failures. Our target is predictive maintenance alerts sent via cloud networks weeks before failure.
By leveraging Narrowband IoT (NB-IoT) and LoRaWAN wireless architectures, the future main gas shut off valves communicate status parameters to centralized safety dashboards. Industrial users monitor system pressure, temperature, and cycle counts globally across multiple facilities simultaneously.
Implementing mechanical micro-pendulums and shape-memory alloy triggers directly within the valve architecture. In the event of high-intensity seismic vibration (earthquakes) or ambient temperatures exceeding 70°C, the valve initiates automatic physical shutdown independently of electrical power supplies.
Engineered safety infrastructures designed to integrate seamlessly across municipal, industrial, and high-density residential networks.
Municipal networks require real-time pressure regulating skids and line break valves. Our networked bus systems link heavy industrial shut off valves to municipal SCADA centers, providing rapid shutdown zones when pressure drops are identified, minimizing pipeline explosion hazards across metropolitan grids.
Processing facilities present explosive atmospheres. Our explosion-proof solenoid shut-off valves and SIL-certified gas detector networks operate in Zone 1 and Zone 2 environments. Constructed with cast steel or SS316, they withstand corrosion, extreme high pressures, and chemical solvents.
Residential high-rises and kitchens depend on automatic shut-off systems linked to local gas sensors. Our household solenoid valves (like the XF2 Series) connect with smart combustible gas detectors. Upon detecting micro-leaks, they output immediate DC electric pulses to cut off the main supply lines instantly.
Located within the industrial hubs of Chengdu and Deyang, Xinhaosi operates two smart manufacturing bases with combined automation capabilities. We have integrated advanced manufacturing practices to ensure production consistency, offering global buyers significant economic and logistics advantages:
Ensure regulatory compliance, longevity, and operational safety by verifying critical parameters prior to bulk imports.
Safety equipment requires strict alignment with localized regulations. Import controls, building safety codes, and occupational safety acts differ between regions. Xinhaosi helps simplify this process for international purchasers:
A history of innovation in gas safety technologies, scaling from a startup to a global factory partner.
Established on April 17th, 2003. We launched our first generation of gas leak alarms and basic fire fighting system components, positioning ourselves in the early domestic safety monitoring market.
Initiated dedicated safety shut off valve manufacturing. We expanded our OEM supply division and relocated headquarters to the Longtan Industrial Park to meet rising production demands.
Achieved 10 million units sold milestone. Relocated to the newly built Chengdu Factory, finalized a nationwide service network in China, and introduced fire power monitoring systems.
Launched our in-house IoT cloud safety platform. Awarded the High-Tech Enterprise status and became a qualified supplier for China's top five gas companies.
