Explore our leading collection of intelligent gateways, low-voltage power units, high-sensitivity gas detectors, and quick-closing wireless emergency solenoid valves.
A Technical Whitepaper on Integrated Gas Safety Systems, Emergency Solenoid Valves, and AI Sensing Technology.
In the realm of commercial facilities and residential complexes, undetected gas leaks represent silent, catastrophic risks. The phrase "Close the Valve" is not merely a manual instruction; it represents the ultimate protective action within automated hazard mitigation workflows. We utilize advanced electronic detection technology to make unknown gas leak risks clear, visible, and automatically preventable.
Founded in 2003, Xinhaosi has spent over two decades establishing itself as one of the most influential and reliable brands in the gas safety industry. Our primary objective is to deliver customer-focused products and services that safeguard the operational integrity of industrial sites, commercial spaces, and municipal grids. Supported by modern production systems, we supply emergency gas shutoff solutions that close the valve instantly when dangerous combustible gas levels are detected.

Modern emergency shutdown systems require seamless coordination between sensors, logic controllers, and physical actuators. Our technical framework is designed around a zero-latency signal transmission scheme, ensuring that when safety limits are exceeded, the interlock system sends a reliable shutdown pulse to cut the flow instantly.
Our smart safety valves integrate AI diagnostic engines that perform self-tests for blockages, pressure spikes, and mechanical degradation. By analyzing pressure fluctuations and valve seating metrics, they flag issues before an emergency occurs.
Equipped with ultra-low-power RF transceivers, our dry battery type wireless solenoid valves connect directly to residential or commercial gas detectors without complex wiring. They operate reliably for up to 5 years on standard cell batteries.
The OEM FDG-X304SE Intelligent Data Gateway manages local sensor grids, aggregates safety telemetry, and runs local edge logic. Even during cloud network outages, the gateway processes inputs locally to close emergency valves.
Different operating environments require safety components designed for their specific conditions. Our systems are engineered to address the unique challenges of several key deployment scenarios:
Operating out of our advanced production centers in China, Xinhaosi leverages a highly integrated local industrial supply chain. This configuration guarantees raw material security, precise quality control, and rapid adaptation to customer specifications.
Our manufacturing processes utilize automated SMD lines, precision CNC machining, and automated flow-test benches. Every solenoid valve and detector undergoes multiple calibration cycles before shipment. This localized integration allows us to offer shorter lead times and cost-effective customization options compared to western competitors, while maintaining full compliance with strict quality standards.
By working with Xinhaosi, global distributors and OEM customers gain access to a reliable, high-capacity production partner capable of scaling output to meet sudden market demands.
Industrial gas safety products must comply with national and regional safety standards to be legally installed and operated. Xinhaosi products are designed and certified to meet demanding international criteria:
We support our international clients through local engineering channels, technical consultation, remote commission training, and quick-response warranty processing.
Our commitment to quality has earned Xinhaosi the trust of municipal utility providers, engineering contractors, and industrial safety distributors worldwide.

Standard solenoid valves open and close electrically depending on the ongoing current supply. In contrast, manual-reset emergency gas shutoff valves are safety devices that close immediately upon receiving an electrical pulse (such as from a gas detector). Once closed, they remain mechanically locked in place to prevent gas from flowing again until a technician inspects the area and manually pulls the reset pin.
Wireless solenoid valves designed for residential and light commercial use typically rely on standard dry cell batteries and operate via RF communication. For hazardous or heavy industrial environments, we recommend utilizing explosion-proof wired configurations (such as the CT-XF5 series) coupled with armored cable lines to ensure reliable signals and satisfy local safety certifications.
The FDG-X304SE gateway functions as the central point of our safety systems. It collects sensor values from wired or wireless gas detectors over Modbus RTU, LoRa, or standard 4-20mA connections. If the gas concentration exceeds safe limits, the gateway triggers the interlock control box (such as the JB-MK-AT2041X), discharging a DC pulse to close the solenoid valve.
Valves deployed in confined underground spaces like utility shafts must hold Ex d (flameproof) or Ex i (intrinsically safe) certifications. Because methane is highly combustible, all electrical connections must be enclosed to prevent sparking, and the components should feature an IP67 or IP68 water resistance rating to withstand damp environments.
