Explore our elite range of explosion-proof monitoring units, smart gas controllers, and integrated safety systems certified for global hazards.
The global transition towards safer, more efficient, and decarbonized energy networks has heightened the demand for advanced Gas Safety Shut Off Valves. In both municipal infrastructure and high-hazard heavy industries, preventing catastrophic gas leaks is no longer just a compliance measure—it is a critical operational safeguard. Today's commercial space requires quick-response solenoid actuation, zero-leakage elastomeric sealing, and robust integration with Distributed Control Systems (DCS).
From hydrogen blending in Europe's natural gas grids to rapid industrialization and strict safety mandates across the Asia-Pacific region, safety shut-off systems must endure high pressures, corrosive environments, and constant thermal cycles. Our engineering solutions address these demands by supplying certified, SIL-capable (Safety Integrity Level) components that instantly isolate gas supply in hazardous conditions.

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.
Discover how our gas detectors, controllers, and safety valves integrate to solve complex safety requirements across diverse operational environments.
In highly explosive zones (Zone 1 and Zone 2), leakage of hydrocarbons can have disastrous consequences. Our solution integrates the GTYQ-AT0601 Explosion Proof Combustible Gas Detector with heavy-duty solenoid shut-off valves. Upon detecting explosive gas concentrations reaching pre-set lower explosive limits (LEL), the detector transmits an instantaneous signal to the controller, triggering the shut-off valve to isolate the main gas header in milliseconds, securing the facility before ignition occurs.
Underground and enclosed parking structures are prone to toxic carbon monoxide accumulation from vehicle exhaust. Utilizing our OEM AT2004BIV-CO Carbon Monoxide Gas Detectors, the system continuously logs CO levels. If concentrations exceed critical safety standards, the controller automatically activates exhaust ventilation systems. If levels continue to rise, the system triggers shut-off valves on any heating utility line running through the park, eliminating fire hazards.
Municipal pipeline systems require remote diagnostic and automation capabilities. Our urban pipeline network monitoring systems track flow integrity and localized pressure dips. By incorporating smart solenoid valves with built-in flow monitoring, operators can execute automated remote shutdowns from the central municipal station during earthquakes, line ruptures, or low-pressure anomalies, mitigating large-scale hazards.
For high-density residential properties, gas safety requires simple, fail-safe devices. Our JT-AT2013A Household Gas Detector combined with the XF2 Series Gas Solenoid Valve offers a reliable domestic defense. The detector monitors for natural gas or LPG leaks, triggering the valve to shut off the gas supply immediately. The valve can only be reset manually, ensuring the safety issue is investigated before gas flow resumes.
Boiler rooms and restaurant kitchens experience rapid temperature shifts and humidity. High-durability detectors linked with low-voltage power units (like the AT2032X Power Box) provide continuous protection. If flameout or line leakage is detected, the solenoid valve shuts off fuel supply immediately, preventing accumulation and potential explosions.
In steel mills and smelting plants, carbon monoxide and explosive gases are common byproducts of high-temperature processes. In these challenging environments, we deploy specialized gas detectors paired with industrial-grade safety shut-off valves. This setup ensures rapid shut-off even in dust-laden, high-temperature settings, protecting workers and key machinery.
At Xinhaosi, we look ahead to see how gas safety technologies must evolve. Our development roadmap focuses on integrating Artificial Intelligence (AI) and the Internet of Things (IoT) directly into our physical control systems. By combining edge computing with our graphical gas monitoring platforms, future safety valves and detectors will shift from reactive devices to proactive, predictive instruments.
By leveraging historical sensor drift data and ambient environmental measurements, our AI-driven systems can flag potential line ruptures or sensor failures before they happen. Furthermore, as the world transitions to hydrogen and renewable gas alternatives, we are updating our valve alloys, seal materials, and sensor technologies to ensure reliable performance with hydrogen-blended natural gas.
