Pioneering security solutions for global industrial, commercial, and household applications.
Realizing safe operation in hazardous production environments through end-to-end integration and robust engineering design.
Gas safety systems form the primary defense mechanism in modern industrial and residential infrastructure. An automatic gas off valve (often designed as an industrial solenoid valve) functions as the key actuator that cuts off gas flow in response to abnormal detection signatures. Selecting a reliable manufacturer is crucial because system latency, mechanical fatigue, or material deterioration could lead to catastrophic events.
At the core of a high-performance valve is the electromagnetic drive combined with a robust mechanical reset structure. In normally open (NO) configurations, such as the KT-XF5 Series, the valve remains open during normal operation with zero electrical power consumption, minimizing long-term operational costs and coil wear. When a gas leak is detected, the controller triggers a pulse electrical signal, releasing the internal latch mechanism and forcing the valve closed within milliseconds.
Conversely, normally closed (NC) configurations, such as the CT-XF5 Series, require continuous power to remain open, acting as fail-safe systems where any power disruption immediately interrupts gas flow. Quality factories achieve distinction by using premium seals like NBR or Viton, and processing valve bodies through high-grade hot forging to withstand heavy municipal pipelines.
Instant response times (<0.3s) ensure immediate isolation of flammable and toxic gases before explosive thresholds are reached.
Engineered using pressure-forged brass and aerospace-grade NBR/FKM elastomers to prevent leakage under high vibrations.
Instantaneous electrical pulses activate the shutoff, minimizing electrical load and keeping running temperatures low.
Targeted protection across civil, commercial, and heavy-industry gas applications.
X Represents the Unknown Risks. X Represents the Next-Gen Safety Technology. Future Ready.
We utilize advanced electronic detection technology to make unknown gas leak risks clear and visible.
Founded in 2003, Xinhaosi has grown into one of the most influential and reliable brands in the gas safety industry. We provide customer-focused products and services to safeguard the operations of modern factories, ensure municipal safety, and protect homes worldwide. Powered by advanced production systems and technology, we deliver reliable, intuitive, and precise gas safety solutions for a safer future.
Our collaborative ecosystems connect sensors, controllers, and mechanical valve arrays. When a hazardous leak is detected by our sensors, the centralized controller initiates an immediate shutdown. This minimizes risk, protects property, and secures lives.
This integration is key to addressing the modern market's demands. Buyers benefit from single-source manufacturing, ensuring compatibility and simplified integration across the entire safety system.
End-to-End Solutions for Total Safety. Empowered by technology, Full-chain integration, Comprehensive protection, Shaping the future with intelligence.
In highly hazardous environments, gas controllers interface with explosion-proof portable and fixed detectors. Solenoid valves are housed in flameproof enclosures (Ex d IIC T6) to operate reliably under extreme pressures and temperatures without risk of sparking.
We design smart pipeline shut-off systems that integrate with building management systems (BMS). Using low-voltage control cabinets, these systems protect public venues, restaurants, and apartments from gas leaks.
Integrating gas detectors with IoT communication modules enables remote valve shutoffs. This allows utilities to monitor pipelines and isolate grid sections during seismic events or pressure drops.
Operating a modern factory requires more than just meeting production demand. It demands strict, data-driven manufacturing frameworks that ensure trace-level component quality. Our production lines utilize automated precision assembly, automatic leakage testing, and computer-controlled magnetic flux monitoring for solenoid coils.
By producing components in-house—from machining brass body casings to winding copper coils—we minimize dependencies on third-party supply chains. This vertical integration protects operations from raw material volatility and guarantees uniform manufacturing standards.
Driving innovation in sensing and actuation to build safer, more reliable industrial systems.
The future of gas safety is shifting from reactive shut-off mechanisms to proactive hazard mitigation. Integrating AI-driven edge computing allows gas detectors to analyze concentration profiles over time, helping distinguish between actual leak hazards and transient chemical vapors. This minimizes false shut-offs, which can cause costly operational downtime in industrial settings.
Our development roadmap focuses on the integration of IoT-enabled, low-power solenoid architectures. These valves transmit system telemetry—such as coil temperature, piston cycle count, and response times—directly to control rooms. Engineers can monitor actuator health and schedule maintenance before failures occur, shifting from static service routines to predictive reliability models.
Additionally, advancements in hydrogen blending within natural gas pipelines demand updated materials. Hydrogen's small molecular structure can compromise seals and copper alloys. Our engineering teams are testing next-generation polymers and composite coatings to ensure long-term durability in hydrogen-enriched systems.
Our products conform to the strictest global regulatory frameworks, supported by localized service hubs.
To support global supply chains, our product lines are certified to meet international standards, including CE, SIL2, explosion-proof directives, and ISO 9001. We provide localization support, comprehensive technical training, fast-turnaround warranty services, and on-site engineering consultations to simplify integration for our partners.

Expert guidance on gas valve selection, installation parameters, and system integration.
Normally Open (NO) valves remain open without electrical power. They are triggered to close by an electric pulse when a leak is detected, and must be manually reset. This prevents automatic reopening after a leak event. Normally Closed (NC) valves require constant power to stay open; they shut automatically if power is lost, making them ideal for systems where continuous power acts as a safety heartbeat.
SIL certification (typically SIL2 or SIL3) quantifies the reliability of a safety function under risk conditions. It defines the probability of failure on demand (PFD). For safety devices like gas off valves in petrochemical plants, SIL2 compliance guarantees the actuator will close when triggered, reducing operational risk.
In commercial and residential kitchens, gas off valves connect directly to local gas detectors or fire panels. When gas concentrations reach a threshold (usually 10% LEL), the controller alerts building occupants and sends a signal to trigger the solenoid shut-off valve, isolating the gas supply.
High-quality factories conduct several tests, including nitrogen gas leakage tests, high-voltage coil performance evaluations, cycle aging tests, and helium mass spectrometer leak detection. These protocols ensure structural integrity and reliable operation under pressure.
