Premium flow control and detection products engineered for critical process safety and environmental monitoring.
Securing energy pipelines and industrial operations through fail-safe automation.
In modern hydrocarbon processing, chemical synthesis, and municipal distribution systems, the integrity of gas transport pipelines is paramount. A 2-inch (DN50) gas shut-off valve is often the definitive line of defense, protecting critical machinery, refinery zones, and residential properties from catastrophic leakage. To prevent explosive thresholds (Lower Explosive Limit - LEL) from being breached, these valves must respond within milliseconds, operating in seamless alignment with remote gas monitoring systems.
At Xinhaosi, we combine mechanical precision with intelligent electronics. Modern industrial settings require more than simple manual valves; they demand solenoid-driven, automatically triggered shut-off mechanisms coupled with explosion-proof detectors. Our solutions are designed to address the dynamic challenges of high-flow gas channels, featuring structural resilience against backpressure, chemical corrosion, and seismic activity.
XINHAOSI TECHNOLOGY
Future Ready: We make unknown gas leak risks clear and visible.
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 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 world.
Our research and development division focuses on transforming complex data sets from electronic detection equipment into immediate safety actions. By utilizing high-sensitivity combustible gas detectors (such as the GTYQ-AT0505 series) connected to fast-acting gas shut-off valves, we guarantee that when an emergency is identified, the gas feed line is shut down instantly. This integrated logic loop minimizes response times and mitigates potential failures, providing a comprehensive safety environment.

Full-chain integration, comprehensive protection, and intelligent system designs.
Safety First from Precision Sensing. Integrated flame monitors (like the FD1020) and combustible gas sensors continuously monitor harsh processing environments, feeding telemetry directly back to interlock control cabinets to manage high-pressure shut-off valves.
Home Safety from Gas Monitoring. Protecting residential buildings, multi-family units, and commercial kitchens with compact, highly reliable combustible gas detectors connected directly to quick-action utility shut-off valves.
Protecting from the Source. Engineered to stop gas flow instantly upon receiving an electrical trigger. Featuring manual reset mechanisms to ensure a safe, verified start-up procedure after a detection event.
Smart Sensing for Urban Gas. Monitoring large-scale municipal pipeline interfaces, distribution vaults, and pressure regulation stations. Utilizing IoT platforms to detect line pressure drops, system leakage, and coordinate regional shutdown protocols.
Advanced production methodologies driving consistent safety standards worldwide.
Our state-of-the-art facility in China operates under strict adherence to international quality management protocols, utilizing advanced CNC machinery, automated assembly, and comprehensive inspection technologies. For components as critical as a 2-inch gas shut-off valve, precision casting and high-tolerance machining are vital to prevent system bypass or slow shut-off responses.
Our production workflow incorporates vacuum-tightness tests, nitrogen pressure tests, and electrical performance evaluations for every solenoid module. Our automated system records calibration metrics for every gas detector and valve, establishing complete traceability for auditing and compliance. This robust manufacturing framework ensures product reliability and helps insulate the supply chain from component shortages.
