Explore our top-performing range of industrial solenoid valves, intelligent wireless pressure monitors, and explosion-proof gas detectors engineered to protect lives and industrial assets.
How emergency shutdown valve (ESDV) systems act as the primary defense layer against hazardous gas build-up, pipeline ruptures, and combustion risks in smart cities and process industries.
Modern municipalities rely on interconnected sub-distribution lines. High-speed safety gas valves close within milliseconds during earthquake detection or network pressure deviations to prevent secondary pipeline explosions.
Operating under extreme process conditions requires explosion-proof gas detection connected directly to automated shutdown loops. Fast-acting solenoid shutoff valves isolate high-pressure combustible gas pipelines safely.
Integrated gas sensors detect leaks in commercial structures, triggering immediate shutdown of incoming utility lines. Xinhaosi systems ensure localized fail-safe operation conforming strictly to NFPA and EN specifications.
Founded in 2003, Xinhaosi is one of the most influential and reliable brands in the gas safety industry. We provide customer-focused products and services to safeguard the safe operation of every factory, the comfort of every city, and the peace and happiness of every home. Powered by cutting-edge production systems and technology, we deliver more advanced, intuitive, and precise gas safety solutions for shaping a safer future world.
We utilize advanced electronic detection technology to make unknown gas leak risks clear, quantifiable, and visible. By integrating state-of-the-art gas solenoid valves, wireless pressure monitors, and flame detection units, we establish complete closed-loop protection lines that minimize response latency in emergency situations.
Learn More About UsOur design integrates sensing, communication, and actuation. If a combustible or toxic gas build-up is detected, the safety response loop triggers automatically.
Deploying fixed industrial gas detectors (such as the XP3000 or GTYQ-AT0505) and multi-spectrum flame detectors (FD1020) provides real-time monitoring of volatile environments. Continuous analysis of ambient atmosphere detects leakages before they reach Lower Explosive Limits (LEL).
Signals generated by detectors or pressure monitors (such as the AT0635 Wireless Smart Pressure Monitor) feed back to dedicated safety controller modules or output devices (AT0321X/AT0322X). Modbus, analog 4-20mA, or IoT wireless protocols route this time-sensitive data directly to the valve control circuit.
The industrial gas solenoid valves (CT-XF5 or KT-XF5 series) act as the final, critical defense block. Featuring normally open or normally closed mechanical architecture, these safety valves trip within 0.3 to 1 second. Fast manual reset mechanisms ensure operators retain control once a safe status is confirmed.
Safety equipment is only as strong as its certifications and its adaptibility to local requirements. We ensure alignment with major global safety guidelines.
Our products are designed for harsh zones. XP3000, XP4000P, and GTYQ-AT0505 series feature ATEX, IECEx, and Ex-d certifications, preventing internal electrical sparks from igniting external hazardous atmospheres.
Designed for high ingress protection (up to IP66/IP67), our detectors and shutoff valve actuator casings withstand severe weather, high humidity, dust, and corrosive petrochemical plant environments.
We build adaptable safety products. From NPT/G pipe threads to global flange standards (ANSI, DIN, JIS), our valves integrate smoothly into existing lines without expensive adapters.

A Normally Open (NO) gas solenoid valve (such as the KT-XF5 or CT-XF5 series) remains open under normal operating conditions. It requires an electrical pulse or continuous signal only to trip shut during an emergency. This is ideal for main gas supply lines to avoid closing during standard power fluctuations. A Normally Closed (NC) valve requires continuous electrical power to stay open, and closes automatically upon power loss, providing fail-safe protection for high-risk processes.
The explosion-proof gas detector (such as the XP3000 or XP4000P) monitors LEL levels. Upon reaching a preset threshold, the detector outputs a signal (via 4-20mA, RS485 Modbus, or an internal relay contact). This signal is routed through an intermediate controller or output unit (like the AT0321X/AT0322X), which cuts or applies power to the solenoid valve, triggering it to shut down the gas line in fractions of a second.
Wireless pressure monitors (like the AT0635 series) allow continuous tracking of pipeline pressures without running complex communication cabling. Sudden pressure drops can indicate a downstream leak, while pressure surges can indicate blockages. Integrated with shutdown valves, these monitors form an active safety net across large commercial plants and urban networks.
Our industrial solenoid valves utilize high-grade materials including cast aluminum alloys, brass, and stainless steel, paired with robust NBR, Viton, or FKM seal systems. These materials prevent chemical degradation, ensuring consistent seal integrity and a long working life, even in environments with trace corrosive components.
