Founded in 2003, Xinhaosi has spent over two decades cementing its position as one of the most influential, technologically advanced, and reliable brands in the global gas safety and control industry. We address complex gas safety hazards by providing custom-tailored, engineered products and end-to-end industrial solutions. Our focus remains clear: to safeguard the safe operation of every chemical processing plant, optimize municipal utility distribution, and bring absolute peace of mind and safety to millions of homes worldwide.
Backed by intelligent production lines, precise automated calibration testing, and a highly skilled R&D team, we continuously push the boundaries of gas safety. We turn unknown, invisible gas leak hazards into structured, visible, and actionable data streams. Our core objective is simple: stop gas leak hazards instantly from the source using high-integrity Gas Solenoid Valves and smart shut-off units.
We utilize advanced electronic detection technology to make unknown gas leak risks clear and visible, driving safety automation forward.
Detection Systems built with precision sensing components to guarantee safety first across heavy hazardous processing zones, oil rigs, and power plants.
Comprehensive monitoring solutions. Advanced sensors capture low-ppm gas leaks, immediately prompting emergency shut-off valves to seal gas mains.
Protecting flow control paths directly from the source. Engineered for microsecond mechanical response, zero pressure loss, and decades of functional duty cycles.
Smart sensing networks integrated with SCADA protocols for metropolitan municipal pipelines, ensuring reliable pressure regulation and safety integrity levels.
In modern process industries and safety-critical infrastructures, a gas solenoid valve is not merely a pipeline component; it is the final element of safety defense. Known as an electromechanically operated valve, its core design focuses on rapid actuation to isolate volatile gases (such as natural gas, LPG, methane, propane, and hydrogen) during leakages, power outages, or physical ruptures. At Xinhaosi, we design and manufacture valves according to strict EN 161 specifications to ensure they function reliably under harsh operational parameters.
Our solenoid valves rely on heavy-duty, high-insulation copper wire coils encapsulated in thermoplastic materials. Standard configurations are designed to withstand continuous energized operations (100% duty cycle) without overheating. For hazardous locations, we provide explosion-proof terminal enclosures certified to Ex d IIC T6 Gb. This ensures that any electrical arc or spark generated within the coil remains completely contained inside the housing, avoiding contact with potentially combustible atmospheres outside the valve body.
The choice of sealing materials is crucial for preventing slow, micro-molecular gas leakage over time. We utilize premium synthetic rubbers, including Nitrile Butadiene Rubber (NBR) and Fluorocarbon Elastomer (FKM/Viton), customized to maintain flexibility down to -20°C and up to +120°C. For corrosive sour gas pipelines, the valve body is constructed from anodized aerospace-grade aluminum, brass, or cast 316 stainless steel, minimizing galvanic corrosion and metallurgical cracking under physical stress.
"Empowered by technology, full-chain integration, comprehensive protection, shaping the future with intelligence."
We supply safety system integration across various industries, guaranteeing zero mechanical failures.
Our valve portfolio is integrated into complex process lines, providing robust performance across major sectors:
Xinhaosi's manufacturing complex represents the pinnacle of Chinese high-end industrial manufacturing. By utilizing Factory 4.0 architectures, we maintain tight control over product consistency, delivery schedules, and price competitiveness. Our factory is equipped with advanced manufacturing infrastructure designed to handle large-scale, high-integrity production orders:
We machine each valve body from single-billet brass or forged alloys using multi-axis CNC machines. This achieves tolerances within ±0.01mm, ensuring a tight seal for every valve produced.
Every single gas safety valve undergoes automated pressure decay and Helium mass spectrometry testing. We verify zero leakage rates (exceeding Class VI gas bubble tight sealing standards) before shipment.
Every valve is laser-engraved with a unique tracking QR code. This allows full quality traceability back to the raw material batch, production operator, and test station records.
This localized supply chain integration allows us to keep lead times under control, even during peak global demand. From raw ingot forging to high-precision coil winding and testing, our facility keeps critical processes in-house. This structure helps protect international clients from supply chain delays, tariff fluctuations, and freight disruptions.
As industrial systems adopt automation and the Industrial Internet of Things (IIoT), the design of gas safety valves is evolving. Our research and development center focuses on three key future initiatives:
With the global push toward hydrogen energy, standard valve designs face the risk of hydrogen embrittlement. Hydrogen's low density also increases the risk of micro-leakage. Our engineering team is currently testing austenitic stainless steels and custom synthetic elastomers. These materials are designed to resist hydrogen penetration and cracking, ensuring reliable performance in up to 100% hydrogen environments.
Traditional solenoid valves run on basic open/close controls, requiring manual maintenance checks to detect internal issues. Our upcoming smart solenoid valve series incorporates diagnostic micro-sensors. These sensors track coil temperature, stroke speed, vibration, and magnetic field changes in real time. They transmit performance data via Modbus or LoRaWAN, allowing operators to plan preventative maintenance before failure occurs.
To support green energy initiatives, we are expanding our range of magnetic latching solenoid valves. Unlike conventional valves that require continuous current to stay open, our latching valves use a momentary electrical pulse to open and a permanent magnet to hold the position. This design reduces energy consumption and limits coil heat generation, which is beneficial for remote, off-grid locations.
Navigating different international safety regulations is a key challenge for global procurement departments. Our gas safety products are designed to meet major national and international standards, simplifying the compliance process for engineering and procurement contractors (EPCs):
In addition to regulatory compliance, Xinhaosi operates a dedicated international engineering service desk. We provide on-site sizing calculations, selection support, custom flange designs, and on-site commissioning guidance. This support helps global clients integrate our valves into existing systems, minimizing startup delays.
Ensure your suppliers meet the following engineering standards:
Officially launching the Handheld Uncooled Infrared Gas Leak Detector, featuring dual-technology fusion, ultra-fast response, and long-distance non-contact detection to enhance safety in petrochemical, refrigeration, natural gas and industrial safety scenarios.
Attended the Chengdu expo, engaging with cross-border e-commerce platforms, global buyers, manufacturers, and supply chain enterprises to expand international cooperation and explore global market paths.
Gathered with enterprises and industry leaders in Chengdu to discuss industrial cooperation, policy frameworks, and market development strategies for Southeast Asian industrial growth.
Our emergency shut-off valves feature an ultra-fast actuation response time of less than 1 second (typically <300 milliseconds for electromagnetic drop out). This instant response is critical for limiting gas release during sudden pipe failures.
We primarily utilize high-density Nitrile Butadiene Rubber (NBR) for standard hydrocarbons and Fluorocarbon Elastomers (FKM/Viton) for corrosive media. These compounds resist degradation from aromatic hydrocarbons and gaseous condensates, maintaining seal integrity over years of service.
Our safety valves are designed with a manual-reset feature (Normally Closed, NC). Once tripped by an electrical signal from a detector or power failure, the valve locks shut. It cannot open automatically when power is restored, preventing accidental gas flow before the hazard is inspected and cleared.
