Explore our cutting-edge gas detection sensors, smart transmitters, controllers, and pipeline safety instrumentation engineered for extreme operating conditions.
In the contemporary landscape of clean energy distribution, safety is the foundational pillar of operational viability. The global reliance on gaseous hydrocarbons demands failsafe mechanisms that prevent catastrophic losses in residential, commercial, and industrial facilities. Natural Gas Cut Off Valves, particularly automatic gas solenoid emergency valves, serve as the ultimate line of defense. By cutting flow within milliseconds of a detected leak, these systems mitigate the risks of explosion, chemical hazards, and severe structural damages.
Modern industrial architectures depend on the integrations of sensing and execution. Integrated systems, combining gas sensors with normally closed solenoid valves, ensure that pipelines are immediately isolated if seismic vibrations, excessive pressure deviations, or chemical leaks occur. The demand for highly certifiable, ruggedly engineered cutoff valves has increased exponentially as international safety standards—such as SIL (Safety Integrity Level) and ATEX explosion ratings—become mandatory in energy, processing, and pharmaceutical industries.

We produce and sell tens of millions of units annually, catering to a wide range of industries that demand reliable gas detection solutions, including oil & gas exploration and production, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, new energy, steel production, and beverage processing.
Guided by the core mission of “Making Gas Safety Accessible Everywhere,” we consistently deliver high-performance, reliable products and customized solutions tailored to each client’s unique needs. Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
Combining structural automation, sophisticated quality controls, and robust localized supply chains to deliver top-tier OEM industrial valves globally.
By controlling all aspects of the supply chain in Sichuan industrial hubs (Chengdu and Deyang), we source high-grade brass, cast iron, and synthetic elastomers at optimal rates, translating to competitive pricing for large B2B custom batches.
Our Deyang production hub integrates automated CNC machining centers, automated coil winding arrays, and computerized leakage-testing benches. This maintains an exceptionally low defect rate (under 50 ppm) over high production volumes.
Our state-of-the-art CNAS laboratory performs dynamic thermal cycle tests, electrical insulation tests, high-vibration exposure, and structural burst limit verifications to meet global standards before exporting to America, Europe, or the Middle East.
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.
Providing customized parameters, structures, and certifications to address safety requirements across multiple industrial scales.
Installed directly on burner supply lines, these heavy-duty solenoid valves function as safety shut-off systems. They integrate with burner management systems (BMS) to stop fuel flow instantly upon flameout detection.
For low to medium-pressure urban gas pipeline structures, our high-capacity solenoid valves offer remote operation capabilities. They link with central IoT monitors to shut down pipeline sections in emergency scenarios.
Designed for malls, restaurants, and hotels, our systems link directly with combustible gas detectors. If gas accumulation reaches 10% LEL, the emergency cut off valve triggers, ensuring public safety.
Constructed with flameproof, cast iron housings, these explosion-proof valves operate reliably under aggressive chemical exposures. They carry high SIL ratings, safeguarding high-hazard manufacturing sites.
Driven by decarbonization initiatives and modern smart cities, gas management systems are transitioning toward digitalized configurations. Real-time diagnostic valves and integrated flow-monitoring models represent the future. The industry demands valves that not only execute emergency commands but also collect pipeline pressure, temperature, and leak telemetry. Predictive maintenance capabilities, backed by digital platforms, allow operators to identify internal valve wear and structural deterioration prior to failure.
Our OEM divisions address these advancements. We manufacture next-generation pressure-monitoring smart valves and bus-type control systems. These units support wireless protocols (LoRaWAN, NB-IoT), enabling operators to monitor and isolate distant nodes from centralized SCADA interfaces.
Global procurement teams demand customized layouts. From customized connection sizes (DN15 to DN300) to distinct pressure thresholds, we support versatile configurations. Our engineers assist you through custom sizing, flange compatibility (ANSI, DIN, JIS), coil voltage settings (DC24V, AC220V), and material choices (aluminum alloy, brass, cast steel).
Additionally, our comprehensive test centers verify that customized products are thoroughly tested, calibrated, and compliant before leaving the facility, preventing deployment issues.
