Explore our flagship selection of safety-certified control hardware, engineered to deliver instantaneous shutdown and real-time monitoring across dangerous gas and liquid environments.
Founded in 2003, Xinhaosi has established itself as one of the most influential and reliable brands in the global gas safety and control valve industry. We provide customer-focused products and services to safeguard the operations of factories, commercial complexes, municipal pipelines, and modern homes worldwide.
Leveraging cutting-edge manufacturing processes and electronic detection technologies, we render dangerous gas leaks fully visible and manageable. Our high-precision solenoid valves and sensors operate seamlessly under harsh conditions, mitigating risk before it escalates.
Detailed breakdown of core engineering criteria, compliance certifications, and material selections vital for safety engineers.
Our solenoid control valves are engineered specifically for instant shut-off of flammable, toxic, and non-corrosive industrial gases. Operating on a pulse/low-power hold mechanism, these valves offer swift mechanical action and ensure zero leakage under low and high pressure pipelines. With ATEX and Ex-proof explosion certifications, they fit perfectly into complex automated processes.
Our solenoids employ dual-windings with automated control circuitry to deliver high start-up force while minimizing energy draw during long holding periods, preventing thermal runaway and coil burnout.
These valves link directly with gas alarm control units and smart interlock systems, enabling automatic mechanical response when a hazard limit is detected.

From complex urban distribution grids to high-pressure petrochemical refineries, our systems ensure complete system safety.
We deploy wireless gas pressure sensors and heavy-duty flanged solenoid shut-off valves in city gate stations. Operating over cellular frameworks, these devices prevent municipal network overpressure, triggering automatically to block mainlines in seismic or massive pipe rupture incidents.
In high-temperature steel smelting and industrial steam plants, double-block-and-bleed valve trains utilize our quick-release solenoid control valves. They interface directly with flame detection systems to vent unsafe gas pockets within milliseconds, avoiding combustion chambers deflagration.
Combining household combustible gas detectors (JT-AT2008 / JT-AT2018) with aluminum low-pressure solenoid shut-off valves ensures home fire prevention. If a cooking or heating line exhibits micro-leaks, the sensor sends a DC 12V pulse to trip the valve closed immediately, prompting physical reset.
Our R&D pipeline integrates every single link of the safety chain. We develop the core gas sensing elements, design the control unit logic, and manufacture the physical solenoid valve bodies in our ISO9001-certified factory floors.
By operating under strict quality protocols, we guarantee total compatibility. Many industrial site failures stem from signal mismatches between sensors and valves sourced from separate OEMs. Xinhaosi bypasses this bottleneck by providing pre-calibrated, fully tested safety kits tailored for specific geographic markets.
Our solutions comply with EN 50194, UL 1484, and GB 15322 test profiles. Every explosion-proof housing matches ATEX directives for Zone 1 and Zone 2 gas hazardous environments.
Trusted by global energy providers, municipal gas boards, and industrial EPC contractors.
