High-performance solenoid shut-off systems and detection interfaces custom-engineered for residential safety and industrial security loops.
The global transition to smart energy systems demands a new tier of safety components. Solenoid valves and automatic shut-off systems are no longer passive mechanical overrides. Modern gas safety requires real-time telemetry, ultra-low standby power configurations, and instantaneous integration with combustible gas sensors. As leading OEM manufacturers and suppliers, we design safety systems that exceed traditional safety guidelines and achieve real security through technology.
Our OEM gas automatic shut-off valves utilize custom-engineered latching solenoid coils. The system stays open in its rest state without consuming power. When the controller detects an anomaly, a micro-second pulse triggers a rapid mechanical collapse, shutting off gas flow in less than 0.3 seconds. This design prevents thermal stress, prolongs system lifespan, and ensures functionality even during total grid failure. When combined with our AT2031XE low voltage power boxes, we deliver continuous uptime for sensitive residential and commercial safety loops.
Residential natural gas pipeline chemistry is evolving as hydrogen-natural gas blends become more common. This introduces hydrogen embrittlement risks to standard valve bodies. Our manufacturing lines use high-grade forged brass (HPb59-1) and high-performance fluoroelastomer (FKM) seals. This ensures excellent durability, leak resistance, and stable mechanical performance across standard natural gas, LPG, and hydrogen-enriched gas mixtures.

We utilize advanced electronic detection technology to make unknown gas leak risks clear and visible. Protecting infrastructure from the source requires combining gas sensors and automatic valves into a single, unified defense system.
We use advanced technology to make invisible gas risks visible and controllable.
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 operation of every factory, the safety of every city, and the peace of every home. Powered by advanced production systems and technology, we deliver reliable, precise gas safety solutions for shaping a safer world.
How our smart manufacturing lines maintain high output, precision tolerances, and cost efficiencies for global OEM distributors.
Using automated CNC machines ensures consistent structural dimensions, preventing pressure leaks under extreme residential pipe stress.
Every valve undergoes helium mass spectrometer leak testing and pressure decay checks. We maintain full batch tracking and zero-defect QA standards.
Strategic partnerships with raw copper smelters and elastomer suppliers guarantee stable manufacturing timelines and consistent pricing, even in volatile markets.
Our ongoing engineering focus centers on adding intelligence directly to safety components. We are actively transitioning from reactive safety elements to smart, self-monitoring systems.
1. Low-Power Multi-Bus Systems: Next-generation valves will support combined RS485 and direct bus architectures (such as the JT-AT2004BII), enabling communication with multiple sensing nodes using minimal cabling.
2. Built-in Micro-Leak Diagnosis: Integrating dynamic pressure-decay logic allows our valves to perform automated self-tests during low-use windows, detecting micro-leaks before they trigger alarms.
3. Energy Harvesting Technology: We are testing pilot valves powered by internal fluid flow, eliminating external electrical requirements for remote deployments.
Operating internationally requires meeting complex local safety standards. Our products comply with strict international regulatory frameworks, including European EN 161 solenoid standards, ATEX explosion-proof directives, and UL requirements for residential gas control devices.
From GTYQ-AT0503/d explosion-proof detectors to the JT-AT3068 series, we supply fully certified components. This lets distributors and developers launch systems worldwide without regulatory delay.
We partner with leading engineering firms and gas distributors to build safer energy delivery networks.

The valve connects directly to the detector's output terminal. When the gas concentration exceeds safe levels, the detector sends a 12V-24V impulse to the valve's latching solenoid, triggering a mechanical shutdown in under 0.3 seconds.
Yes. Our latest valves use HPb59-1 forged brass and specialized FKM seals. This combination helps prevent hydrogen embrittlement and micro-leaks, making them compatible with gas blends containing up to 25% hydrogen.
We provide comprehensive OEM customization. This includes custom body sizing (DN15, DN20, DN25), various connection types (flanged, threaded, bypass configurations), custom solenoid voltages, and custom brand labeling.
Every single valve undergoes pressure decay testing and a helium leak detection scan. We maintain full material test report (MTR) records and tracking codes for complete quality assurance.
Our safety systems integrate with several wireless configurations, including LoRaWAN, NB-IoT, standard RF (433MHz), and RS485 Modbus. This flexibility allows for easy integration into smart home systems and industrial setups.
Our solenoid valves are tested to exceed 20,000 cycles. Because they use a pulse-latching mechanism, the coil remains unpowered and cool during normal operation, preventing thermal wear and extending the valve's lifespan.
Our explosion-proof detectors (such as the GTYQ-AT0503/d and GTQ-XP4000) feature flameproof cast aluminum housings. They are designed to contain internal sparks and meet ATEX/IECEx certifications for zone 1 and zone 2 hazardous areas.
Standard OEM production runs take 25 to 35 days, depending on custom tool requirements and batch size. Thanks to our integrated factory in China, we maintain a stable material supply chain to deliver reliable lead times.
Explosion-proof detectors, multi-point control boxes, and industrial-grade wireless terminals designed for complete infrastructure protection.
