Premium safety components and monitoring systems engineered for harsh industrial environments.
Founded in 2003, Xinhaosi has established itself as one of the most influential and reliable brands in the global gas safety and automatic valve control industry. For more than two decades, we have engineered and manufactured robust 1 gas valves (1 inch / DN25 gas valves), explosion-proof detector systems, and integration interfaces. Our mission is clear: to eliminate unknown hazards using advanced sensing and mechanical safety technologies.
Operating from our advanced China-based factories, Xinhaosi brings together state-of-the-art production systems, highly precise manufacturing tolerances, and raw material validation procedures to supply the world’s most demanding industries. By integrating electronic detection capabilities with reliable mechanical shut-offs, we provide end-to-end infrastructure protection that shields cities, industrial zones, and millions of homes worldwide.
Under the hood of industrial-grade 1" (DN25) automatic emergency shut-off valves.
A premium 1 gas valve is defined by its housing integrity. Xinhaosi utilizes high-grade hot-forged brass, carbon steel, and anodized aluminum alloys designed to withstand internal pressure surges up to PN16/PN25 ratings. This ensures maximum crack resistance and prevents micro-porosity leaks.
Equipped with proprietary electromagnetic trip mechanisms, our 1" gas solenoid valves deliver instantaneous shut-off times of less than 1 second. The mechanical manual-reset configuration ensures that the flow cannot resume until the hazard is cleared.
For combustible gas atmospheres, safety is non-negotiable. Our valves feature flameproof electrical enclosures certified to meet Ex d IIC T6 Gb standardizations, guaranteeing that electrical spark generation inside the solenoid coil cannot trigger external ignition.
End-to-End solutions designed to integrate sensing instruments with immediate mechanical responses.
High-sensitivity IR/UV optical flames detectors and combustible gas sensors for industrial environments.
Smart detectors optimized for methane, LPG, and CO gases, protecting homes and kitchens.
Rugged 1-inch and multi-size safety shutdown valves that block gas flows instantly during alarms.
Integrated telemetry, RTUs, and wireless nodes to oversee municipal natural gas pressure lines.
Inside Xinhaosi's smart production complex, where technology guarantees reliability and massive output.
Our factory leverages fully automated CNC machining centers, high-pressure die casting setups, and robot-assisted calibration benches to manufacture 1 gas valves with micro-millimetric consistency. Every valve undergoes extensive bubble leak testing, electrical coil resilience testing, and pressure drop tests before departing the assembly floor.
By utilizing vertically integrated manufacturing protocols, we eliminate standard delays associated with sub-tier sourcing. From raw brass extrusion to final packaging and testing, Xinhaosi ensures a secure, uninterrupted chain of custody. This structured factory layout translates into shorter lead times, lower unit costs, and high-volume consistency for B2B distributors globally.
How our 1" gas safety valves function within wider industrial and smart city applications.
In volatile petrochemical areas, small hydrocarbon leaks can escalate quickly. Our 1" explosion-proof solenoid valves sit inline with distribution lines, wired directly to UV/IR flame detectors and controller panels, providing instant local isolation when hazardous gas levels are crossed.
Restaurants, commercial boiler loops, and shopping complexes depend on steady, regulated gas supplies. Xinhaosi’s 1 gas valves offer low pressure drop and high flow coefficients (Cv), preventing downstream starvation while assuring immediate mechanical shut-off during seismic movement or fire emergencies.
Integrated with municipal RTU telemetry gateways, our wireless-enabled control configurations allow city maintenance personnel to close district lines remotely. This shortens incident times and keeps local distribution infrastructure safe.
The global transition to cleaner energy brings new challenges to traditional valve networks. Hydrogen (H2) molecules, being extremely light and active, present high permeability risks. Xinhaosi's engineering division is actively designing next-generation 1 gas valves featuring special hydrogen-compatible soft seats, leak-proof micro-seals, and anti-static housings.
In parallel, we are introducing embedded AI diagnostics within the actuator housings. By continuously measuring solenoidal electrical waveforms and mechanical travel speeds, these smart valves can predict seat wear and return spring fatigue before failures occur. This proactive approach helps operators avoid unplanned downtime and maintain high safety standards.
Navigating global regulations, custom OEM requests, and technical compliance.
All Xinhaosi 1 gas valves and explosion-proof components are tested to satisfy strict global certifications (including CE, ATEX, and Chinese national standardizations). This ensures seamless acceptance by safety inspectors and site developers.
Whether you need customized operating voltages, NPT/BSP thread standards, or special corrosion-resistant coatings for harsh marine areas, our engineering team can custom-tailor valves to your specific requirements.
We back every product with detailed manuals, calibration logs, and step-by-step diagnostic guides. Our team provides responsive technical support to help you configure, install, and troubleshoot complex setups.
