Explore our leading range of precision-engineered solenoid valves, wireless terminals, and intelligent gas monitors designed for instant hazard mitigation.
As a leading OEM Gas Shut Off Supplier, Xinhaosi has spent more than two decades perfecting the engineering dynamics of gas control systems. When combustible gases or carbon monoxide reach critical thresholds, milliseconds determine the difference between safety and catastrophic failure. Our solenoid valves and automated shut-off systems act as the terminal execution layer of smart safety networks.
Our solenoid valves are engineered with a fast-acting electromagnetic trip mechanism. In the event of a detected leak, a pulse signal triggers the latching coil to close the valve instantly, requiring a manual reset to ensure that gas flow is only restored after the system is fully inspected and cleared by professionals. This physical fail-safe design guarantees maximum operational security across residential, commercial, and heavy industrial properties.
"We integrate high-sensitivity gas detection terminals with rapid-action physical barriers. This end-to-end synergy ensures that emergency gas shut-off operations occur in under 0.5 seconds, minimizing flammable gas dispersion in closed spaces."
Chengdu R&D Headquarters & Assembly Center
Founded in 2003, Xinhaosi has built an integrated production ecosystem that merges R&D, advanced automation, digital distribution, and CNAS-certified testing.
Deyang High-Capacity Smart Manufacturing Plant
Xinhaosi is recognized as one of the most trusted names in gas leak detection and valve automation. Guided by the core mission of **"Making Gas Safety Accessible Everywhere,"** we operate state-of-the-art facilities in Chengdu and Deyang. Our multi-facility footprint allows us to segment R&D prototyping and high-volume, automated production lines to meet complex international client requests.
Our comprehensive portfolio features explosion-proof gas detectors (such as the GTYQ-AT0601 series), smart wireless communication modules, and robust industrial gas solenoid valves (such as the XF3III series). Every product we manufacture undergoes extensive pressure holding, environmental aging, and response-time testing before shipment.
Adhering strictly to ISO9001 quality management systems, our products hold CCC, explosion-proof, fire safety, CPA measurement type approval, and international certifications like CE and SIL2. We are also honored to serve as a primary standard-drafting organization for Chinese domestic gas safety solenoid valve regulations.
Why international EPC contractors, municipal gas groups, and OEM brands choose Xinhaosi as their long-term supply chain partner.
Our factories leverage China's deep industrial cluster for metals and electronics. From raw brass casting and precision CNC forging of valve bodies to custom electromagnetic coil winding, we manage the entire value chain. This integration prevents supply bottlenecks and guarantees consistent chemical compositions for gas-contact surfaces.
With multi-million unit yearly capacities, we utilize semi-automated calibration tables, high-speed SMT lines for detector motherboards, and automated pressure decay leak test chambers. This level of scaling lowers per-unit costs, allowing us to pass significant financial margins back to our global OEM distributors.
We do not offer a single take-it-or-leave-it product line. Our R&D team works closely with global engineers to adjust threads (NPT vs. BSPT), customize voltage parameters (DC9V-12V pulse, AC220V, DC24V), modify structural materials (stainless steel, ductile iron, forged brass), and flash customized firmwares onto wireless intelligent terminals.
From residential smart housing complexes to highly combustible petrochemical plants, our systems deliver targeted protection.
Modern residential towers rely on real-time protection. If a kitchen range experiences flameout or a flexible pipe cracks, our household combustible gas detectors (such as the JT-AT2013A) instantly sound a localized siren, flash warning LEDs, transmit an alarm signal to the property management system via wireless IoT channels, and close the dry battery-powered wireless solenoid valve at the main meter. This prevents gas build-up before the homeowner is even aware of the issue.
Smart car parks present a high risk for carbon monoxide accumulation due to slow-moving vehicle exhausts. By deploying our AT2004BIV-CO Carbon Monoxide Gas Detectors, facility managers can monitor PPM levels across large subterranean levels. If concentrations exceed safe limits, the detectors interface directly with the building’s HVAC ventilation systems to trigger air exchange and shut down localized heating gas inlets if anomalies persist.
In refining, petrochemical storage, and chemical manufacturing, the environment demands explosion-proof instrumentation. We supply certified intrinsically safe and explosion-proof gas detectors (such as the GTYQ-XP4000B and GTYQ-AT0502) paired with flame detectors like the FD1020 / FD2010 Triple IR Flame Detectors. These systems withstand volatile atmospheres, triggering massive flanged industrial solenoid shut-off valves in sub-second intervals when hydrocarbons or open fires are detected.
Integrating the GT-AT0637 Wireless Smart Pressure Monitor and the FDG-X304 Intelligent Data Gateway, municipal gas companies can track pipeline pressures remotely. Sudden pressure drops (which indicate a rupture or severe leak) trigger automated shut-off sequences across affected distribution segments, isolating sections of the grid to protect downstream urban populations.
Discover our key developmental milestones as we grew from a regional manufacturer into an international gas safety powerhouse.
Choosing an OEM Gas Shut Off Supplier involves looking beyond standard unit pricing. To achieve long-term field reliability, buyers should evaluate products against the following criteria:
Xinhaosi's internal laboratory is fully accredited by the **China National Accreditation Service for Conformity Assessment (CNAS)** and recognized globally via the **ILAC-MRA** framework. Our facility operates in compliance with **ISO/IEC 17025**, the international standard for testing and calibration laboratories.
This accreditation confirms our ability to perform precise calibrations and tests on gas detection instrumentation, solenoid valves, and telemetry devices. As a result, the test reports issued by our facility are accepted by certification bodies and regulatory offices worldwide. This authority helps streamline international customs clearance and local compliance approvals for our global clients.
